Abstract
A substrate-processing method includes a) forming a flowable oligomer on a substrate, the flowable oligomer containing carbon; and b) exposing the substrate to a plasma of a modification gas containing carbon and hydrogen, thereby modifying the flowable oligomer and forming a carbon-containing film.
Claims14
A substrate-processing method, comprising:
- a) forming a flowable oligomer on a substrate, the flowable oligomer containing carbon;
- and
- b) after completion of the formation of the flowable oligomer, performing a plasma modification process using a modification gas containing carbon and hydrogen, thereby modifying the flowable oligomer and forming a carbon-containing film.
