Abstract:
1. A manufacturing apparatus for a semiconductor device, performing film formation for a wafer, comprising: a reaction chamber to load a wafer; a gas supply unit for supplying first process gas including source gas from an upper portion of the reaction chamber; a rectifying plate for supplying the first process gas onto the wafer in a rectifying state; a first gas exhaust unit for exhausting gas from a lower portion of the reaction chamber; a second gas exhaust unit for exhausting gas from an upper portion of the reaction chamber; a heater unit including a heater for heating the wafer and a susceptor for retaining the wafer; a rotation drive unit for rotating the wafer, the rotation drive unit connected to the heater unit; and a fin for generating a gas flow from a rotating shaft to an outer periphery, the fin disposed between the heater unit and the bottom face of the reaction chamber.
