Title: Manufacturing for epitaxial wafer
Inventor: SUEYOSHI HACHINOSHIN
IPC: H01L21/205
Filed: 1995-04-04
Abstract: PURPOSE: To prevent a polysilicon from attaching to a chamfered face or an edge face on the rear side around a wafer, along with good yield, by controlling epitaxial growing speed at a given level. CONSTITUTION: A chlorosilane-based gas like SiCl4 , SiHCl3 OR SiH2 Cl is used as a growth gas. The growth speed can be adjusted by increasing or decreasing the amount of growth-gas supply. Even with an epitaxial layer 3 with a thickness of 100μm or above, the amount of attached polysilicon to a chamfered face 1a or an edge face 1b of a rear face of the wafer is reduced abruptly in the vicinity of 1.2μm/sec of the epitaxial growth speed so that a yield in good products can be increased. With the thickness below 5μm of polysilicon layer at the chamfered face 1a and the edge part 1b, flaking between the epitaxial layer 3 and the polysilicon layer caused by thermal strain at lowering temperatures is prevented even when there is a difference in specific heat among the epitaxial layer 3, the polysilicon layer grown there, and the scepter 2.  As a result, a yield in manufacturing can be improved.
