Abstract

A semiconductor wafer processing apparatus comprises a reaction furnace capable of heating inside thereof, a wafer mount for mounting a semiconductor wafer thereon and a transfer device. The wafermount includes an opening which is greater than the semiconductor wafer and which has a circle shape or a shape substantially similar to an outer periphery of the semiconductor wafer, and includes a wafer supporting portion projecting inwardly of the opening for supporting the semiconductor wafer. The transfer device is capable of holding the wafer mount outside the semiconductor wafer as viewed from a vertical direction, and transferring the wafer mount carrying the semiconductor wafer thereon substantially horizontally into and/or out from the reaction furnace.
