Patent ID: 8741110

Claim:
A method of forming a film comprising the steps of: preparing a base plate having a first oxide region and a second oxide region composed of mutually different oxide materials; and selectively conducting a film deposition on the second oxide region by a bias sputtering, wherein R 1-a /R 2-a >1.2, S a <R 1-a ·G ion , and S a >R 2-a ·G ion , and wherein R 1-a is a sputtering rate of a material (a) when the material (a) is deposited with a thickness of 0.3 nm on the first oxide region, R 2-a is a sputtering rate of the material (a) when the material (a) is deposited with a thickness of 0.3 nm on the second oxide region, S a is an irradiation amount of the material (a) to be deposited on the base plate, and G ion , is an irradiation amount of ions of a gas species to the base plate, and wherein a film deposition rate of depositing a first atomic layer on the first oxide region is smaller than 0, and a film deposition rate of depositing a first atomic layer on the second oxide region is larger than 0, wherein S a −R 1-a ·G ion is the film deposition rate of depositing the first atomic layer on the first oxide region, and S a −R 2-a ·G ion is the film deposition rate of depositing the first atomic layer on the second oxide region.
