Title: Emmanuel Guidotti: Innovator in Surface Morphology and Chemical Vapor Deposition

Introduction

Emmanuel Guidotti is a notable inventor based in Barberaz, France. He has made significant contributions to the field of material science, particularly in the area of surface morphology and chemical vapor deposition. With a total of two patents to his name, Guidotti's work has implications for various industries, including semiconductor manufacturing.

Latest Patents

Guidotti's latest patents include a method of improving surface morphology and reducing resistivity. This innovative method involves producing a thick metal film on a substrate surface that exhibits a substantially smooth surface morphology and low resistivity. The process begins with exposing a substrate to plasma, followed by the deposition of a first thin metal film via chemical vapor deposition. The substrate, now with the deposited film, is again exposed to plasma, allowing for the deposition of a second thin metal film on top of the first. This cycle can be repeated until the desired film thickness is achieved, resulting in a film characterized by a smooth surface and low resistivity.

Another significant patent by Guidotti is a method of eliminating edge effects in chemical vapor deposition of metals, such as copper, on semiconductor substrate surfaces. In this method, a susceptor within a reaction chamber is exposed to plasma, ensuring that the substrate processed by chemical vapor deposition has a uniform metal layer across both edge and non-edge surfaces. This technique allows for the processing of multiple substrates before the susceptor needs to be re-exposed to plasma.
