Title: Susceptor for vapor growth of semiconductor
Inventor: TANJI HIROAKI
IPC: H01L21/205
Filed: 1985-11-25
Abstract: PURPOSE:To improve the yield of products by specifying the surface roughness of crystalline aluminum nitride in the coating layer. CONSTITUTION:The surface roughness of crystalline aluminum nitride in a coating layer is brought to 350mum or less in Rmax. When the surface roughness of the AlN coating layer exceeds 350mum in Rmax, the yield of products from the same wafe remarkably lowers, and only the improvement of yield of approximately 1.1 times or 1.8 times as high as the use of a conventional SiC coated susceptor can be realized. It is thought that the microscopic temperature uniformity of the wafer deteriorates on vapor growth because the wafer and the susceptor are brought into contact only at a small number of points in the susceptor with a rough surface in which surface roughness exceeds 350mum in Rmax.
