A fixture for supporting a semiconductor wafer during rapid thermal processing, comprising a two-piece assembly of parts, one of which is a silicon carbide wafer support section having a wafer contact face shaped by direct contact with a mold, during its formation by chemical vapor deposition. The other piece is a holding section shaped to keep the wafer support section in place within the reactor. The two-piece assembly improves thermal performance, compared with a one-piece fixture, because the rate of heat conduction across the gap between parts is always less than the rate of heat conduction through a one-piece fixture having the same dimensions.
