FILM DEPOSITION APPARATUS
First Claim
1. A film deposition apparatus for depositing a film on a substrate by carrying out a cycle of alternately supplying at least two kinds of reaction gases that react with each other to the substrate to produce a layer of a reaction product in a chamber, the film deposition apparatus comprising:
- a rotational member that is rotatable around a vertical axis inside the chamber;
a rotation mechanism configured to rotate the rotational member;
a pedestal provided in the chamber, the pedestal including a plurality of substrate receiving areas formed along a circle having the vertical axis as a center;
a first reaction gas supplying part provided in the rotational member and configured to supply a first reaction gas to the pedestal;
a second reaction gas supplying part provided in the rotational member and configured to supply a second reaction gas to the pedestal, the second reaction gas supplying part being separated from the first reaction gas supplying part along a circumferential direction of the circle;
a separating area provided in the rotational member along the circumferential direction of the circle, the separating area being arranged between a first process area to which the first reaction gas is supplied and a second process area to which the second reaction gas is supplied for separating an atmosphere of the first process area and an atmosphere of the second process area;
an evacuation port configured to evacuate an atmosphere inside the chamber;
a separation gas supplying part provided in the separating area and configured to supply a separation gas; and
an opposing surface part provided in the separating area on both sides of the separation gas supplying part in the circumferential direction of the circle and arranged at a position forming a thin space between the opposing surface part and the pedestal for allowing the separation gas to flow from the separating area to the first and second process areas.

Abstract
A film deposition apparatus including a rotational member is rotated by a rotation mechanism around a vertical axis inside a chamber, a pedestal in the chamber and including substrate receiving areas formed along a circle having the vertical axis as a center, and first and second reaction gas supplying parts provided separately along a circumferential direction of the circle and supplying first and second reaction gases to the pedestal, a separating area in the rotational member and between first and second process areas to which first and second reaction gases are supplied, an evacuation port to evacuate an atmosphere inside the chamber, a separation gas supplying part in the separating area for supplying a separation gas, and an opposing surface part in the separating area on both sides of the separation gas supplying part and at a position forming a thin space between the opposing surface part and the pedestal.
