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

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

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

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.

Vacuum Coaters wet coating technology and coating technology
Membrane extensive selection of vacuum coating technology, you can control the thickness of the film and coating system functionality and performance of different films, can make a lot of new material with chemical and physical properties.
Wet coating technology is way past a coating that plating or electroplating, chemical reduction of the principles applied in the material deposited, this method will produce waste polluting the environment, in the past a lot of plating plant because of pollution problems have changed the coating process .
Vacuum coating system film coating technology, the film less susceptible to contamination, in a vacuum environment can be improved purity and compactness, no waste without pollution. Vacuum coating itself is contaminated, but the actual vacuum system will be used in organic coatings, it will also cause pollution, but compared to the wet plating technique, a lot less pollution, high efficiency vacuum coating technology has strong vitality, but it does not mean that vacuum coating technology can completely replace the traditional wet coating technology, and in the thickness of the film, the anti-aging still take advantage of the wet coating method, vacuum coating thin film coating system.
In addition, a solid layer is affected by the process and adhesion, either wet or vacuum coating technology coating technology, if the material surface is not clean and will affect the binding layer material.
With the development of science and technology, vacuum coating technology industries has become a means of improving product quality, low cost vacuum coating significant economic benefits so that more and more companies eager, China's production of vacuum coating machine has reached a considerable level, the system can be plated vacuum coating materials are also more and more, but the foreign equipment and contrast a little gap also exists for the development of vacuum technology to be improved.
