Title: Wafer support
Inventor: SHIMADA MASAYUKI
IPC: H01L21/68
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To provide a wafer support which is superior in thermal fatigue resistance because thermal stress generated in it due to thermal cycling is small. SOLUTION: A wafer support is a ring-shaped flat plate, provided with an opening 11 where a wafer is housed and which is located at its center, and a step 12 protruding in an inner radial direction is formed symmetrical about a thicknesswise center line at the center of an inner circumferential cross section (center axis-containing cross section). Similarly, a step 13 protruding in the outer radial direction is formed symmetrical about a thicknesswise center line at the center of an outer circumferential cross section (center axis-containing cross section). Since the wafer support is symmetrical in sectional shape about its thicknesswise center line, the temperature distribution of the wafer support generated by a change in thickness is improved in symmetry with respect to the center line.  Therefore, thermal stresses generated in the wafer support is small, and the wafer support is enhanced in thermal fatigue resistance.

Title: Plasma treatment method and device thereof
Inventor: SINIAGUINE OLEG
IPC: H01L21/677
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To uniformly perform plasma treatment on the surface of an article such as semiconductor wafer and to enable increase in the productivity of a plasma treatment system. SOLUTION: Articles are rotated by a first driving device 140, in such a manner that the articles are put in and out from plasma during a plasma treatment period. The first driving device is made to rotate by a second driving device 150. Consequently, the angle at which the articles enter the plasma varies with the position of a first axis. The cross-section of plasma on the level where the plasma and the article cross each other is symmetrical, so that the higher the linear speed of points on the article (due to the long distance from the first axis), the longer the passage distance in the plasma becomes. Accordingly, plasma treatment time becomes more uniform for points on the surface of the article.
