Title: Dry etching processing method for small metal gate on thin gate dielectric body and product manufactured thereby
Inventor: KRAFT ROBERT
IPC: H01L21/3213
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To enable a gate electrode stack to be formed on an ultra-thin gate oxide without causing it to be damaged. SOLUTION: A dielectric structure of metal-conductive diffusion barrier-gate is manufactured through a step 110, in which a barrier material and an inner metal are etched through plasma-assisted anisotropic etching, and the remainder of the barrier layer is etched 110 through a dry chemical downstream etching process, while the barrier layer is not exposed to the ions impact. When tungsten is etched on a titanium nitride, an etching process of high selectivity and satisfactory characteristic is realized by the use of the combination of a low temperature, comparatively low bias and addition of nitrogen, and when a titanium nitride is etched, it is preferable that a chemical downstream etching method be used in place of a usual wet etching (in boiling H2 SO4 ) (with this method, an undercut is well controlled, and a wet strip process can be eliminated).

Filed: 1985-04-26
Abstract: PURPOSE:To obtain the titled separator capable of separating oil of a vane compressor under operating conditions of wide range by providing plural fins for striking a refrigerating gas contg. oil against a partition plate. CONSTITUTION:A refrigerant spouted from the discharge port 25 of a rear plate 9 of a vane compressor passes through a hole 26 and flows into the first space 47 formed by a partition plate 30 and a plate 27. The flow velocity is remarkably decreased at that time, the refrigerant strikes against a zigzag- arranged fin 31 of the partition plate 30 and oil is separated at this time. The separated oil is held in a pocket formed by the fin 31. The gas is likewise struck against fins 34 and 37 of partition plates 33 and 36 and separated. The gas leaving the fin 37 passes through a hole 40 and flows out into a refrigerating cycle. The oil held in the pocket flows into a chamber and is used for lubrication. Accordingly, a compact separator can be formed and high oil separation efficiency can be obtained.
