Title: Vincent Arnal: Innovator in Semiconductor Technology
Introduction
Vincent Arnal is a prominent inventor based in Grenoble, France. He has made significant contributions to the field of semiconductor technology, holding a total of 10 patents. His work focuses on improving the efficiency and performance of integrated-circuit devices.
Latest Patents
One of Vincent Arnal's latest patents is related to the fabrication of a diffusion barrier cap on copper-containing conductive elements. This method involves providing a substrate with a Cu-containing conductive element embedded in a dielectric layer. The process includes depositing a metal layer on the exposed surface of the conductive element, inducing diffusion of metal into the top section, and allowing the diffused metal to react with particles of a second constituent to form a compound that acts as a diffusion barrier against copper diffusion. This innovation helps reduce the dielectric constant of the dielectric material in an interconnect stack of an integrated-circuit device.
Another notable patent involves a method for forming metal interconnects in a dielectric material. In this process, a trench is formed in the dielectric layer, and the exposed portions of the dielectric layer that form the side walls of the trench are removed. A dielectric liner made of a second dielectric material is then deposited on the side walls of the trench, enhancing the performance of the semiconductor device.
