Abstract:
An apparatus for processing a semiconductor substrate, comprising:a reaction chamber; a susceptor within the chamber for supporting a substrate thereon when processed, said susceptor having at least three vertical through-holes at designated positions; substrate-supporting members slidably fitted in the respective through-holes, each substrate-supporting member being hollow and having an upper closed end and a lower open end, each substrate-supporting member being reciprocally slidable along the through-hole between an upper position where the upper end protrudes from the susceptor and a lower position where the upper end does not protrude from the susceptor, wherein when the substrate-supporting members are at the upper position, the substrate is supported apart from the susceptor by the upper ends of the substrate-supporting members; and pins corresponding to the respective substrate-supporting members, each pin having an upper end, each pin being slidably fitted in the hollow of the substrate-supporting member, said upper end being inserted in the hollow of the substrate-supporting member and pushing upward the substrate-supporting member to move the substrate-supporting member to the upper position by movement of the susceptor relative to the pins, the upper end of each pin being detached from the closed end of the substrate-supporting member positioned at the lower position by movement of the susceptor relative to the pins.
