Patent ID: 8753448

Claim:
An apparatus for manufacturing a compound semiconductor by use of metal organic chemical vapor deposition comprising: a reaction container; a holder on which a formed body is to be placed so that a formed surface of the formed body on which layers of a compound semiconductor are to be formed faces upward, the holder being arranged in the reaction container; and a material supply port supplying a material gas of the compound semiconductor into the reaction container from outside, wherein the holder includes a support member supporting the formed body so that an undersurface of the formed body and a top surface of the holder on which the formed body is to be placed keep a predetermined distance, wherein the support member is a separately formed member of the holder inserted into at least three locations of a circumferential edge of the holder on which the formed body is to be placed, wherein the support member of the holder includes: a support surface for supporting an outer circumferential edge of the undersurface of the formed body; and an inclined surface configured to form a predetermined angle with respect to the support surface, and wherein the height of the inclined surface relative to a groove formed in the top surface of the holder gradually increases from the support surface in the direction of an outer circumferential edge of the holder.
