Title: Youichi Sasaki: Innovating the Future of Semiconductor Technology

Introduction

Youichi Sasaki is a prominent inventor based in Kanagawa, Japan, known for his significant contributions to semiconductor technology. With a total of three patents to his name, Sasaki has left a notable mark in the field through innovative materials and methods that enhance performance and reliability in electronic devices.

Latest Patents

Among his most recent patents is the development of a carbon-containing silicon oxide film that exhibits high ashing tolerance and adhesion. This semiconductor device features an interlayer insulating film that is strategically formed on a semiconductor substrate, with an opening that reaches a lower layer metal wiring conductor. The film is characterized by a metal plug filled with a copper-containing metal via a barrier metal. A key aspect of this invention is the presence of Si─CH2 bonds within the carbon-containing silicon oxide (SiOCH) film, which plays a crucial role in its functionality. The proportion of Si─CH2 bonds to Si─CH3 bonds, as measured by the peak height ratio in the FTIR spectrum, falls within a range of 0.03 to 0.05, which enhances the film’s overall properties.

Another notable patent by Sasaki includes a similar insulating film that serves as an interlayer insulating film for semiconductor devices with a low dielectric constant. This innovative insulating film also comprises a carbon-containing silicon oxide (SiOCH) film, reinforcing its high ashing tolerance and improved adhesion to SiO2 films compared to conventional SiOCH films that contain only CH3 groups.
