Film deposition apparatus and film deposition method
First Claim
1. A film deposition method to deposit a thin film on a substrate, the film deposition method comprising steps of:
- placing a substrate on a substrate receiving area on a turntable provided in a vacuum chamber, the substrate including a concave portion formed in a surface thereof;
rotating the substrate receiving area by rotating the turntable;
heating the substrate on the turntable up to a predetermined film deposition temperature to deposit a thin film;
depositing the thin film on the substrate by repeating a first step of forming at least one of a molecular layer and an atomic layer on the substrate by supplying a process gas from a process gas supply part to the substrate on the turntable, and a second step of modifying the at least one of the molecular layer and the atomic layer by plasma, by supplying a plasma generating gas into the vacuum chamber and by converting the plasma generating gas to plasma in a plasma treatment part; and
modifying the thin film by heating the substrate up to a temperature higher than the predetermined film deposition temperature,wherein the step of depositing the thin film is performed by supplying a second process gas reactable with the process gas to the substrate from a second process gas supply part provided away from the process gas supply part in a rotational direction of the turntable,wherein the process gas supply part is provided in a process area, and the second process gas supply part is provided in a second process area,wherein a separation area is provided between the process area and the second process area, and the step of depositing the thin film includes a step of supplying a separation gas to the separation area to separate the process area and the second process area, andwherein the step of modifying the thin film is performed by using a plurality of heat lamps provided over the separation area and arranged along the rotational direction of the turntable and by heating the substrate from a plurality of locations along the rotational direction of the turntable.

Abstract
A film deposition apparatus includes a turntable to rotate a substrate thereon, a process gas supply part to supply a process gas to form a thin film on the substrate, a heating part to heat the substrate up to a predetermined film deposition temperature to form a thin film, a plasma treatment part to treat the thin film for modification, a heat lamp provided above the turntable and configured to heat the substrate up to a temperature higher than the predetermined film deposition temperature by irradiating the substrate with light in an adsorption wavelength range of the substrate, and a control part to output a control signal so as to repeat a step of depositing the thin film and a step of modifying the thin film by the plasma, and then to stop supplying the process gas and to heat the substrate by the heat lamp.
