    摘要: A semiconductor manufacturing apparatus which can process the surface of a wafer uniformly and requires a small installation floor area and has an excellent maintainability. The apparatus comprises a vacuum enclosure including at least one wafer mounting stage on its bottom plate, and a cylinder surrounding the wafer mounting stage, and at least one cylinder lifting mechanism disposed for each cylinder for moving the cylinder vertically to vary the clearance between the cylinder and the top plate or bottom plate of the vacuum enclosure and for separating the space outside the cylinder constituting a transfer chamber for transferring the wafer from the space inside the cylinder constituting a process chamber for processing the surface of the wafer, wherein the transfer chamber includes a wafer transfer mechanism for transferring the wafer between the process chamber and the transfer chamber through the clearance, the process chamber has a process chamber gas feed port and a process chamber gas exhaust port, and said transfer chamber has a transfer chamber gas feed port and a transfer chamber gas exhaust port.

    摘要: In a microwave plasma-processing device, a shower plate or plasma penetration window opposed to a board to be processed is recessed on the side opposed to the board to be processed, whereby a decrease in plasma density in the peripheral region of the board to be processed is compensated. As a result, even when plasma processing at low pressure, such as etching, is effected, stabilized uniform plasma is maintained in the vicinity of the surface of the board to be processed. Further, such arrangement enhances ignition of plasma.

    摘要: This instrument can measure parameters of a plasma accurately and easily even though the plasma is excited by a high-frequency. The instrument for measuring parameters of a plasma generated in a vacuum chamber by high-frequency discharge at a given frequency comprises a wire (106) for electrically connecting a first electrode (101) arranged in a space where a plasma is produced and a terminal (110) arranged outside the vacuum chamber for taking out signals, and a first insulator (105) so arranged as to cover at least a part of the surface of the wire therewith. The absolute value of the impedance at the given frequency between the first electrode and the ground when looking into the terminal side from the first electrode is five times or more the absolute value of the impedance at the given frequency between the first electrode and the plasma in a state where no direct current flows through the first electrode.
