Semiconductor processor with wafer face protection |
摘要 |
A semiconductor processing station which utilizes a processing head and processing base which are complementary to enclose a processing chamber. The processing head shown has a rotor with two portions both of which rotate. The rotor has axial movable portions which include a piece holder. The piece holder supports a wafer or other semiconductor piece being processed. The piece holder can be axially extended and retracted relative to a thin membrane which acts as a cover to prevent chemicals from reaching the back side of the wafer during processing.
