IPC: C30B25/12
Filed: 1989-03-28
Abstract: PURPOSE:To lower the content of foreign matter in a formed film and to uniformize the film thickness by making the surface roughness of a wafer contact surface smaller than that of the other surface and covering the entire surface with vitreous carbon. CONSTITUTION:The susceptor main body 1 is machined to 2-5mu surface roughness Ra and 15-30mu Rmax. The wafer contact surface 2 of the main body 1 alone is lapped to <=1mu Ra and <=10mu Rmax. A soln. of a pitchy carbon precursor obtained by thermally decomposing an org. polymer such as PVC in an inert atmosphere is applied on the main body 1 and calcined in a vacuum, etc., to coat the surface of the main body 1 with vitreous carbon in 2-5mu film thickness. Consequently, a graphite susceptor for CVD with the roughness of the surface 2 made smaller than that of the other surface 3 is obtained. When the susceptor is used, the electrical resistivity and uniformity of the formed film are improved, and the yield of the film formation is increased.
