Vacuum coating machine system

  Vacuum coating machine system

Vacuum coating machine plasma beam sputtering coating machine mainly by the rf plasma source, vacuum system, the electromagnetic coil (transmitter coil and convergence coil), bias power supply, vacuum chamber (including target material and the substrate, etc.), vacuum control system, etc. Its salient features are its plasma control system, plasma control system is a key part in coating machine, including rf plasma source located at the side of the vacuum chamber, and and sputtering target materials on the plasma source outlet below configuration with an electromagnetic coil respectively. When two coil direction through current, magnetic field coil synthesis will guide electronic along the magnetic field generated in plasma source direction, so that the plasma beam bound on the magnetic field direction. With a negative bias of target at the same time, make the sputtering ion in electric field under the action of accelerating impact target surface, produce sputtering.
Vacuum coating machine control system of plasma
Vacuum coating machine this coating machine has very flexible control mode, such as sputtering rate can be changed by adjusting the bias of target and the plasma source of rf power adjusted this two ways. Plasma generator and the separation of the vacuum chamber design is the key to the wide range controllable sputtering process parameters, and the broad range of control parameters makes the particular application access to the optimization of process parameters. In addition, you can through the control system of vacuum sputtering rate adjustment.
Vacuum coating machine as shown in the curve for the target current and bias, a constant current density when the sputtering rate and the relationship between the target bias, with constant current rf power is 500 w.

Vacuum coating vendors would introduce coating control mode wavelength

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.

Optical coating equipment for film coating system

Optical coating equipment for film coating system

In the optical coating, it is often nothing more than a contact glass, optical aerospace industry for relatively scarce material through the optical film coating system to achieve the effect of a specific function which is the value of the film exists.
The film refractive index mainly to reduce or eliminate reflected light lenses, prisms and other optical surface, the optical element, in order toreduce light reflection loss element, in which a transparent dielectric film surface coating system, known as an anti-reflection or antireflection film, antireflection coating effect is closely related to the refractive index of the film thickness.
Transmittance and optical coating film refractive index-related, then the thickness of the film there is no relationship? In many complex optical systems, inhibition of the emitted light is very important, relatively speaking, the color of the emitted light more advanced optical system will be more and more, after the experiment, the film thickness to substantially affect light transmission is relatively small, if the thickness of the film something down, you will find the emitted light and reflected light a B exist nc * 2D optical path difference.
