Disc support structure
摘要:
A support structure composed of Si or SiC for supporting semiconductor crystal discs during annealing or doping thereof. A somewhat tube-shaped member having at least one flat side is formed by thermal deposition of a gaseous silicon compound onto a similarly shaped carrier member and the tube-shaped member is then cut and mechanically processed in directions parallel and perpendicular to the axes of the tube to form a support structure having a flat base and upwardly extending curved side walls.
