Abstract:
A semiconductor wafer processing apparatus, comprising:a reaction furnace for heating a semiconductor wafer; a wafer mount for mounting the semiconductor wafer thereon, said wafer mount including an opening having a diameter which is greater than a diameter of the semiconductor wafer and which has a circular shape or a shape substantially similar to an outer periphery of the semiconductor wafer, and including a wafer supporting portion projecting inwardly of said opening for supporting the semiconductor wafer; and a transfer device for transferring said wafer mount carrying the semiconductor wafer thereon substantially horizontally out from said reaction furnace, said transfer device holding said wafer mount outside the semiconductor wafer when said transfer device transfers said wafer mount, as viewed from a vertical direction, at the opposite sides with respect to each of two tangent lines at the outer periphery of the semiconductor wafer mounted on said wafer mount, said two tangent lines being in parallel to a transferring direction for transferring said wafer mount out from said reaction furnace by said transfer device.
