Patent ID: 6837940

Claim:
A film-forming device with a substrate rotating mechanism, which comprises: a susceptor in the form of a circular disk and provided at an outer periphery thereof with a revolution input section; a base plate positioned below the susceptor and rotatably retaining the susceptor via a bearing supported between bearing grooves each provided at the susceptor and the base plate; a first rotating mechanism including at least one revolution generating section, the revolution generating section rotating the susceptor at the outer periphery of the susceptor by way of generating a rotating force at the revolution input section wherein the revolution generating section and susceptor are coplanar; a plurality of substrate tray retaining sections positioned circumferentially around a rotation axis of the susceptor; a plurality of annular substrate trays provided at an outer periphery thereof with a rotation input section and rotatably supported in the corresponding substrate tray retaining sections for supporting a plurality of substrates; a second rotating mechanism including a rotation generating section, the rotation generating section rotating the substrate trays by way of generating a rotating force at each rotation input section, a plurality of the substrates being supported in the corresponding substrate trays, the substrates being revolved by the rotation of the susceptor and rotated by the rotation of the substrate trays to apply a certain film-forming process; a reacting chamber extending across the rotation axis of the susceptor an surrounding the substrate tray retaining sections; and a temperature control mechanism positioned in the reacting chamber.
