Abstract:
1. A wafer processing chamber, comprising: an upper section secured in an immobile state, the upper section including a cavity region defined by a cavity sidewall and a cavity top surface, the cavity region being openly accessible at a bottom surface of the upper section, the upper section having a pathway for receiving a wafer into the cavity region; a lower section connected to a movement mechanism, the lower section being defined by a top surface and a sidewall, the lower section configured to be moved into the cavity region of the upper section such that the sidewall of the lower section is adjacent to the cavity sidewall; a first seal disposed between the cavity sidewall and the lower section sidewall; and a second seal disposed on the top surface of the lower section, the second seal configured to be enabled through contact with both the cavity top surface and the top surface of the lower section, the second seal being configured to enclose a periphery of a wafer processing volume when contacting both the cavity top surface and the top surface of the lower section.
