description PROBLEM TO BE SOLVED: To provide a support member capable of inhibiting warpage of a substrate during heat treatment, in particular, deposition, and to provide a semiconductor manufacturing apparatus having the support member.SOLUTION: A support member 50 includes: a flat plate 51 on which a wafer W is placed; and a wall 52 which is provided at a part of an outer periphery of the flat plate 51 so as to be arranged along an outer peripheral edge of the flat plate 51 and is formed higher than one main surface of the flat plate 51. An inner peripheral surface 52a of the wall 52, which is positioned at the one main surface side, is formed into a taper shape that may hold the wafer W. The wall 52 is formed so as to be higher than the wafer W placed on the other main surface of the flat plate 51. An inner peripheral surface 52a of the wall 52, which is positioned at the other surface side, is formed into a taper shape that may hold the wafer W.
