Mr. Amron Gary, Everyone in the optical coating industry is working with these materials (and many other). They can be deposited by Resistive sources (sort...
Gary: Deposition methods vary based on substrate and required film performance/properties... Evaporation of SiO2 through basket style filaments using...
Hi Gary, Besides sputtering and evaporation, SiOx can also be deposited by PECVD. SiOx films by PECVD can be clear and can be deposited at high rates. We can ...
Hello, I´m sending you this e-mail regarding one question submitted two months ago about tribology of CNx (see original question below). Hi, Regarding this...

Hello: The Cr Targets in ARC PVD system are starting to get cracks in the wear grove and the other one started having big pits on it. Any comments on...
Dear Gary, Probably the target material is not homogenous in the bulk or the target is sintered from Cr powder. Similar pits are evident in AlTi alloyed...

Can I remove an antireflex coating, of a glass surface, by a chemical processes(for example with an acid)? Which other methods are avaliable for research and...
Hi, I've tried Ni-Ag evaporation using e-beam system equipped with diffusion pump on silicon wafers but adhesion is not very good. I assume cryo pump should...
Hello everyone, I will be sputtering several metal films that will vary in thickness, from 600Å to 5000Å. These films will to too reflective for ellipsometry...
Hi, We're currently redesigning one of our sputtering chambers and have encountered a doubt of which I would appreciate if someone from this forum might...
Dear All, We are looking for a manufacturer of vacuum valves. But these valves must be identically in construction to those of the company Leybold concerning...
Dear all, I am looking for End Hall ion source power supply - not a brand new one, used, "second hand", non-expencive, but in a good working conditions....
Evaporated nickle is very tensile stressed and does not adhere to most anything. Try 100-400A of Cr or Ti before the Ni. Use 150-250C heat. I have done this...
Dear collegues, I write to you, expecting for your help. I´m working with YSZ films (8YSZ), but I need to find the thermal conductivity of the films grown...
