Abstract
Abstract A method for forming a deposited film comprises forming in a vacuum chamber housing a substrate therein a deposited film containing silicon on the substrate by subjecting a gas represented by the general formula: ##STR1## wherein R 1 , R 2 , R 3 and R 4 , can be the same or different and are each independently hydrogen or a hydrocarbon group, to polymerization.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
83 words
A method for forming a deposited film, comprising subjecting a gas represented by the formula: ##STR4## wherein R 1 , R 2 , R 3 and R 4 are the same or different and are each independently hydrogen or a hydrocarbon group, in a vacuum chamber housing a substrate therein, to at least one energy selected from the group consisting of plasma energy, light energy and heat energy to hereby polymerize said gas and form a deposited film containing silicon on the substrate.
Claim 2
Independent Claim
83 words
A method for forming a deposited film, comprising subjecting a gas represented by the formula: ##STR4## wherein R 1 , R 2 , R 3 and R 4 are the same or different and are each independently hydrogen or a hydrocarbon group, in a vacuum chamber housing a substrate therein, to at least one energy selected from the group consisting of plasma energy, light energy and heat energy to hereby polymerize said gas and form a deposited film containing silicon on the substrate.
