Abstract:
1. A semiconductor substrate jig used for arranging a film on one surface of a semiconductor substrate, wherein said semiconductor substrate jig comprises: a cylindrically shaped outer frame; and an expandable member arranged within said cylindrically shaped outer frame, and a floor extending across said cylindrically shaped outer frame, the expandable member having a bottom part attached in an air tight manner to said floor, and a fluid joint provided in the center of said floor and said bottom part of said expandable member, and increasing or decreasing volume while deforming a shape of said expandable member by being supplied with fluid therein through said fluid joint; wherein said shape is deformed so that said film arranged between said semiconductor substrate and said expandable member is pressed against said semiconductor substrate as a contacting portion of the expandable member to the film is enlarged outwardly from the center of said film as said volume increases.
