Abstract:
1. An apparatus for manufacturing a semiconductor, comprising: a chamber configured to load a wafer into the chamber; a gas supply mechanism configured to supply process gas into the chamber; a gas discharge mechanism configured to discharge gas from the chamber; a supporting member configured to support the wafer; a rotating member configured to support an outer portion of the supporting member and to rotate the wafer supported by the supporting member; a heater provided in an inner space of the rotating member and spaced from the supporting member, the heater having a slit and the heater configured to control a temperature of the heater to heat the wafer to a predetermined temperature; a push-up base configured to mount the wafer in a lifted state and the push-up base configured to be housed in the slit in a lower state; a vertical rotation drive control mechanism configured to move the push up base in a vertical direction between the lifted state and the lower state, and to rotate the wafer by rotating horizontally the push-up base in the lifted state when the wafer mounted on the push-up base is preheated by the heater; and a rotation drive control mechanism connected to the rotating member and configured to control a rotating speed of the rotating member so as to be separated from a rotating control of the push-up base.
