摘要:
Disclosed is a method of making an anodized aluminum susceptor capable of withstanding an elevated temperature of 590° C., or a temperature as high as 475° C. in the presence of an NF3 plasma, without peeling or cracking, which preferably comprises selecting a high purity or low magnesium aluminum alloy, roughening the surface of the alloy, and then anodizing the surface roughened alloy in an electrolyte comprising an organic acid to form the desired anodized aluminum oxide coating thereon. Further, the invention comprises a high purity or low magnesium aluminum alloy susceptor and an organic acid anodic coating thereon highly resistant to spalling or cracking at elevated temperatures.
摘要:
A tungsten silicide film is deposited from WF.sub.6 and SiCl.sub.2 H.sub.2 onto a substrate so that the tungsten to silicon ratio is substantially uniform through the thickness of the WSi.sub.x film, and the WSi.sub.x film is substantially free of fluorine. The film can be deposited by a multi-stage process where the pressure in the chamber is varied, or by a high temperature, high pressure deposition process in a plasma cleaned deposition chamber. Preferably the SiCl.sub.2 H.sub.2 and the WF.sub.6 are mixed upstream of the deposition chamber. A seeding gas can be added to the process gases.

摘要:
A tungsten silicide film is deposited on a substrate from a premixed deposition gas mixture comprising: (i) silicon source gas, such as SiCl.sub.2 H.sub.2 and (ii) tungsten source gas, such as WF.sub.6. A seeding gas, such as silane, is used during the initial deposition stages to deposit a substantially uniform interfacial WSi.sub.x layer on the substrate, so that the tungsten to silicon ratio of the WSi.sub.x layer is substantially uniform through the thickness of the WSi.sub.x film. An apparatus for performing the process is also described.
