Patent ID: 8607733

Claim:
An atomic layer deposition apparatus for forming a film on a substrate by producing plasma using a reactive gas, the atomic layer deposition apparatus comprising: a first chamber which is surrounded by walls, on which a first supply hole for the reactive gas is formed; a second chamber which is surrounded by walls, on which a second supply hole for a source gas is formed; an antenna array which is provided in the first chamber, the antenna array including a plurality of rod-shaped antenna elements provided in parallel respectively to produce the plasma using the reactive gas; a substrate stage which is provided in the second chamber, the substrate being placed on the substrate stage; a connecting member which connects the first chamber and the second chamber to supply, from the first chamber to the second chamber, gas containing reactive gas radical produced by the plasma; a first gas supply unit connecting through a first pipe to the first chamber and being configured to supply the reactive gas to the first chamber; and a second gas supply unit connecting through a second pipe to the second chamber and being configured to supply the source gas to the second chamber, the gas containing the reactive gas radical produced by the plasma using the reactive gas, and the source gas being alternately supplied to the second chamber.
