Why double door coater coating when two gate voltage difference is very big

Should be a magnetron sputtering, but don't know whether I reaction sputtering, if is reactive sputtering, low voltage film slow is normal. Have not seen a similar coating machine, don't know whether two cavity is same? If not, there may be a flat place, but the speed is fast enough, show that the pressure is no problem. In addition, the stand or fall of magnet tests only target on the surface of the magnetic field strength is good, the higher the magnetic field intensity, the lower the voltage. Power supply is intermediate frequency or dc or rf, twin target, if not need to pay attention to whether the power cord connect anti? Made no mention of target's own reason, may be in the air oxidation, surface to sputter, with fine gauze after polishing time target practice.
In addition, the target water not too cold. When exposed to atmosphere are easy to be surrounded by water. Swap of vacuum coating machine equipment suggested that the two target location, so you can find out the cause of the target and magnet or coating chamber.

Vacuum coating machine equipment troubleshooting

Processing of fault point to find the vacuum coating machine fault point can be processed according to local conditions, simple solution is to change, small to aprons, bolt; Big to valve, vacuum pump, can change as long as there is at hand. For part should be according to the requirements for welding, after welding has yet to confirm whether meet the requirement. Maintenance should pay attention to the link when maintenance should be paid attention to several links. Namely, disassembly, cleaning, testing and assembly.
Vacuum equipment, big or small belong to precision machinery equipment, it is very important. Remove the should follow the principle of light to take light put, can't foolhardy, must not use a hammer to knock. When cleaning parts to clean thoroughly, in order to identify problems and find out hidden trouble. Vacuum pump products and general machinery products have bigger difference, general machinery products more collapse chamfer, and the edges and corners of vacuum pump and clear, very easy to hurt the hand should be more careful, be sure to keep in mind. Don't pour the edges.
Inspection is a delicate work, every detail is not to fall off, any tiny place is likely to be the problem, so can't exist fluky psychology. Whether use gasoline or other solvents to clean vacuum pump parts, be sure to wait for gasoline or solvent volatilization completely to assembly. If the vacuum pump oil and other oil mixed solvent or water damage the performance, affect the performance of the vacuum pump. Aprons wipe up, be careful to check the presence of defects and cracks, the size is correct, wrong size will affect the sealing. Wherever the heating position of aprons, every time remove the cleaning must change, each interface such as oil pump, pump parts when assembly also need to take put down light; Screw the strength should be both, should from diagonal is tight. Dynamic seal multi-purpose shaft seal, shaft seal on carefully, check the shaft seal itself with and without defects, the sealing face whether level off, the shaft seal spring elasticity, thin in the inside of the shaft seal can be coated with a layer of vacuum grease on the shaft seal when the strength should be both, the shaft seal skeleton don't partial pressure, the partial will spill, leak, shaft seal spring don't squeeze, not the shaft seal spring shaft seal failure.
Pay attention to the shaft seal and shaft concentricity, some pumps are used for wheel connection, coaxality of wheel is very strict, assembly from all around the shaft to quantity, guarantee the parallel line. Roots pump is the key to adjust the gear two 8 type gear not touching. The walls of diffusion pump and spray tower had better use dry habotai after clean. Due to the domestic production of diffusion pump mainly depends on the length of the electric stove wire to control the temperature of the oil pump, diffusion pump oil injection is to consider the actual situation of local power grid deliberate to increase or decrease. Amount of different diameter size oil pump also has difference, low voltage power grid oil can reduce 2 mm, as long as it is clean steel rod or wire can be used to measure. Due to the difference on the manufacture and use, diffusion pump oil quantity are for reference only. Maintenance in haste, without even knowing the fault for granted to begin dismantling, had not added new disease, in addition to complicate the simple question.

What is the working principle of various coating way?

What is the working principle of various coating way? In accordance with the coating for vacuum coating machine mainly can be divided into: evaporative deposition, ion plating and magnetron sputtering coating, so how do they work?
The formation of sputtering deposition technology is the use of vacuum glow discharge, accelerate the positive ions make its bombardment of sputtering target material surface phenomenon, make out the surface of the target material particle deposition to form a thin film to the substrate.
Working principle of evaporative coating is put membrane material in vacuum coating indoor, after evaporation source heating evaporation, when the evaporation molecular mean free path is greater than the linear dimensions of the vacuum coating chamber, the steam of atoms and molecules escape from the surface of the evaporation source, little impact of other molecules or atoms and the obstacles, can directly reach the plating surface of the substrate, due to the low substrate temperature, then condensation and film.
Tial principle is the use of vacuum arc discharge counts in the evaporation source technology, is the source of ignition under vacuum evaporation (cathode), and self sustaining formed between anode arc discharge, which emitted from the cathode arc light point cathode material of ions.
Vacuum coating machine company, points out that because of the current local concentration, lead to the joule heat to the cathode material partly ionization, such as explosive to bias in the work under the action of combined with the reaction gas, which is deposited on the workpiece surface is formed by plating layer.

Vacuum coating machine coating principle is what?

Vacuum coating machine coating principle is what? Vacuum coating machine is the product into during equipment widely used, with the rapid development of electronic industry, vacuum coating machine, coating quality gradually improve, so that we use in our everyday life come into contact with the plating products more and more.
In a sense, vacuum coating was also determined by the vacuum coating oil, in the vacuum coating, coating oil mentioned strong adhesive coating and the role of the metal film, it is in pieces at the bottom of the coating, plating and surface coating in the plating.

How to buy vacuum coating machine, it is necessary to pay attention to

With the vigorous development of the vacuum coating industry, also more and more high to the requirement of vacuum coating machine, because the customer's products are constantly upgrading, all kinds of new product material appeared constantly, all kinds of coating requirements more and more complex, we now buy vacuum coating machine pay attention to the following three points:

First of all, the processing power of the vacuum coating machine shell Seemingly cases do not have what difficulty, every vacuum equipment factory can work, but a lot of knowledge, a device of light is not enough to have good vacuum system, vacuum chamber if processing is bad (such as welding), that this equipment to buy back to the customer will have a headache, processing of bad equipment often appear a few small leakage, pressure is not stable, and even some puzzling problems (such as stainless steel plating on titanium as long as more than 3 minutes in furnace into purple, no more than is normal, this is we meet client instance). So here we sincerely recommend our customers to buy the vacuum coating equipment as far as possible choose processing strength of the manufacturer (have) of machining center and other processing equipment.
Second vacuum system configuration as the saying goes, a penny a points goods, price and quality is actually a proportional to the relationship, even if is the same function of the equipment, different configuration, the price must be different, configured vacuum coating machine, long service life and easy to operate smoothly, but the low configuration equipment, problems, foibles, seriously affect the production schedule.
The last is not package process, don't buy equipment.
This is one of the most important among three o 'clock, because the core of the realization process is evaporating source (target) or electron gun, etc.), ready to evaporation source to develop the stability of the coating process, don't understand the process of manufacturer also do bad to evaporation source, good evaporation source is through continuously to improve to make all kinds of coating research, craft do bad evaporation source also do bad, so come to the conclusion that do bad evaporation source manufacturer all need not consider. Generally buy vacuum coating machine, therefore, must choose a proofing coating machine manufacturers, to take samples to plating, plating out samples can reach their testing requirements, in combination with the appeal two decision to buy or not. Equipment manufacturers must do a good job in the factory before the church your own equipment operators after the coating process and equipment factory warranty free coating process consultation and guidance.

The development of the vacuum magnetron sputtering deposition

The development of the vacuum magnetron sputtering deposition
So-called sputtering can be in the charge particles (usually with positive ions of inert gas) to bombard solid surface (hereinafter referred to as the "target"), so as to cause the target material on the surface of the atoms or molecules to escape from it a phenomenon. This phenomenon is glover (Grove) in experimental study in 1842, the cathode corrosion problems, cathode materials have been migrated to the vacuum tube wall. Vacuum coating machine to use this method of sputter deposition film on the substrate was introduced in 1877. Using this approach, however, exist in the early stages of the deposition film sputtering rate is low, film speed is slow, and must be set on high pressure and the device into the inert gas and so on a series of problems. As a result, the slow development of nearly eliminated. Only in the strong chemical activity of precious metals, little metal, get a small amount of medium and compound material application. Until the 1970 s, with the advent of magnetron sputtering in a timely manner, making sputtering deposition has been rapid development, started to go the way of revival.
This is because the magnetron sputtering method by orthogonal electromagnetic field on electronic constraints, increased the probability of electrons collide with gas molecules, such not only reduced on the cathode voltage, and improve the positive ions on target cathode sputtering rate, reduce the probability of the electron bombardment substrate, thus reducing its temperature, namely with the "high speed, low temperature" two big characteristics. In the 80 s, although he appeared just ten years, it will stand out from the lab, truly entered the field of industrial production. And, with the further development of the science and technology, in recent years in the field of sputtering coating introduced ion beam enhanced sputtering, ion source using broad beam intensity flow combined with magnetic field modulation, and combined with the conventional diode sputtering formed a new sputtering mode. And, again will be introduced to the intermediate frequency ac power magnetron sputtering target source. This is called the twin sputtering targets intermediate frequency ac magnetron sputtering technology, not only eliminates the anode effect "disappear". And also solve the problem of cathode "poisoning", which greatly improved the stability of the magnetron sputtering. For large-scale industrialized production of the preparation of compound film provides a solid foundation. Revival and development of coating has rapidly in recent years as people quite a new preparation technology of thin film and active in the field of vacuum coating technology.

Vacuum pump in the vacuum coating equipment

Vacuum pump in the vacuum coating equipment, equipment operation will generate heat, if increase the hot conditions, such as the temperature increases, so the load of equipment will also increase, under this situation, how to maintain?
First: to prevent the vacuum pump or avoid vacuum pump is placed in the sun! As far as possible let the vacuum pump in a cool place, vacuum pump should pay attention to in the outdoor place cannot let vacuum pump exposure in the sun. Itself high vacuum pump temperature during work time, if it is difficult to heat, temperature vacuum pump increases, once reach zero boundary temperature of the vacuum pump, mechanical failure will occur!
The second: the vacuum pump in ventilated place or interior is equipped with cooling device can also be! Willing to also is same, just to let the vacuum pump cooling performance is better, the lower the temperature in the vacuum pump work as much as possible.
Third: material timely replacement. One of the most important is: oil and oil mist separator (exhaust filter)! These two kinds of material must be timely replacement. Exhaust filters if scrap or other quality problems when replacing the first time! Oil a color change color, sediment increase, began to appear the phenomenon such as emulsifying can't just stay in the refueling and maintenance, all want to replace the vacuum pump oil.
Fourth: before the hot weather of vacuum pump for a thorough cleaning and maintenance.

What to buy vacuum coating machine equipment should pay attention to?

Large investment funds items, we will be very careful when buying, it would be ready before the purchase of the required detailed understanding of the work done, a vacuum coating machines are not cheap, with the fast development of vacuum coating industry, for the film to be coated product requirements are also gradually increase, for the use of materials is also gradually expand the scope, and that the vacuum coating machine to keep the product in terms of rhythm with a certain challenge. Now we have to introduce a few precautions to purchase vacuum coating machine.

First, the configuration of the vacuum system: quality and price will always be proportional, regardless of what kind of technology the purchase of machinery and equipment, evaporation or, ions or, magnetron sputtering, or, the same function of the machine, with different configuration, the price is definitely a difference. In general, the use of materials on behalf configured well, the natural life will be longer, the efficiency will be higher, film better.

Second, the vacuum coating machine housing: If the surface, basically difficult to see is good or bad, not only from the surface gives the visual effect to distinguish the case basically every vacuum equipment manufacturers can be processed out. For the case should focus on sealing, welding is very important, if you buy back the equipment found to have leakage problems that customers will be very headache, even indirectly, some inexplicable problems, causes leak occur often because processing not good. Therefore, customers choose to buy vacuum coating machine / coating equipment when we must focus on processing power.

Third, the core technology: the different processes used in the core is not the same, unified call evaporation source, but it is a target head or electronic guns. If you do not have good evaporation source, basically not try to complete the stable quality of the coating. Good evaporation source is needed after years of constantly improve and perfect coating of data and then come out, do not understand the process of evaporation source manufacturers difficult to do. If what manufacturers say that their equipment does not include the process, some do not buy it.

Fourth, field trips, samples proofing: Before you buy or coating equipment vacuum coating machine, take samples to coating, check the film coating system is not able to reach their own requirements, its technical service and after-sales service is not perfect, combined with the above mentioned consulting Consulting more points, the last shop around

Vacuum coating vendors would introduce coating control mode wavelength

Vacuum coating machine, vacuum coating vendors would introduce our materials for its membrane layer of materials, figure 1. The experimental results obtained for SiN film plating. Curve 1 is the reflection spectrum of epitaxial wafer before coating, curve 2 and 3, respectively corresponding to the film thickness of 95 nm and 135 nm, film thickness with elliptic partial instrument to measure. From the curve 1, film e - lh peak at 840 nm, e - hh peak at 848 nm, the location of the pattern wavelength at 832 nm. In type Chang Tong modulator, mode wavelength position should be in e ￣ hh peak of long wavelength direction; And often shut device, pattern wavelength location should be near the e - hh peak, and the top must be decreased membrane plating, otherwise the device will work in the saturated zone, reduce the modulation features of the device. Because the pattern wavelength position is not appropriate, to adopt the method of plating SiNO minus the membrane to move mode wavelength.
Vacuum coating machine, vacuum coating vendors would introduce 2 film thickness of 95 nm by curve of reflection spectrum, the wavelength shifted, but as a result of surface reflectivity, ASFP cavity resonance absorption and exciton absorption compared to compare weak, so can not see clearly on the curve mode wavelength position. Measured with elliptic partial instrument, the film refractive index of 1.8 or so, move about 10 nm wavelength by a theoretical calculation of the mode, at about 842 nm. After coating, e - hh peak of significantly lower reflectivity, although the model at this time Wavelength in e - hh peak position, but because the pattern wavelength from closer to make e - hh exciton peak near the reflectivity of reduce a lot.
Vacuum coating machine, vacuum coating vendors would introduce three film thickness of 135 nm by curve reflection spectrum shows that compared with the mode wavelength before coating, coating mode wavelength decreases after, from the original 832 nm to 832 nm. Film refractive index is 1.8, from the above theoretical analysis shows that when the refractive index of 1.8, film thickness increased to 135 nm, the model about 10 nm wavelength will drop, curve 3 belongs to this kind of situation.
