Patent ID: 8741779

Claim:
A method of producing a semiconductor device through a plasma processing on a semiconductor substrate, the method comprising the steps of: putting a semiconductor substrate to be processed in a processing chamber in which a dielectric body is provided as to be opposed to a microwave radiating surface, radiating a microwave for exciting a plasma from the microwave radiating surface in the processing chamber, wherein a distance D between the microwave radiating surface and a surface of the dielectric body facing away from the microwave radiating surface, which is represented with a wavelength of the microwave λ, to be in a range satisfying an inequality 0.7λ× n/ 4 ≦ D≦ 1.3λ× n/ 4 ( n being a natural number) and wherein no additional microwave radiating antenna is located between the microwave radiating surface and the dielectric body.
