Title:
成膜方法
Document Type and Number:
Japanese Patent JP6951584
Kind Code:
B2
Abstract:
A method of forming a film of this invention includes: rotating, inside a vacuum chamber, a to-be-processed substrate with a center of the to-be-processed substrate, while revolving the to-be-processed substrate on the same plane about a revolution shaft; and feeding a film-forming material from a film-forming source to form a predetermined thin film on a surface of the to-be-processed substrate. Provided that a goal film thickness of the thin film to be formed be defined as T, and that a film thickness of the thin film to be formed on the to-be-processed substrate in one revolution period be defined as D, the method further includes a setting process for setting a ratio α of rotation angular velocity Ωrot to a revolution angular velocity Ωrev of the to-be-processed substrate to a value satisfying the following formula (1)α≥6/log10(T/D)  (1)
