Latest Patents

Inukai's latest patents include a method of removing resist and a method of fabricating a semiconductor device. The method of removing resist addresses the challenge of preventing an increase in the dielectric constant of low permittivity insulating films. It involves using a resist mask, a protection insulating film, a MSQ film, and a silicon oxide film, which are dry etched sequentially to form a via on the substrate surface. The subsequent process includes removing a modified layer formed during prior etching using plasma gas and completely removing the resist mask through the irradiation of hydrogen active species.

The method of fabricating a semiconductor device involves forming a metal wire on a substrate and creating an interlayer insulating film on top of it. A resist pattern is then formed on the interlayer insulating film, followed by selective etching to create a trench or via-hole that reaches the metal wire. The process concludes with ashing using a reducing gas to eliminate the resist pattern.
