Title: The Innovative Contributions of Gregoire Grandremy

Introduction

Gregoire Grandremy is a notable inventor based in Dresden, Germany. He has made significant contributions to the field of semiconductor technology, particularly in the area of etching processes. With a total of 2 patents to his name, Grandremy continues to push the boundaries of innovation in his field.

Latest Patents

One of his latest patents is an etching process for a two-layer metallization. This novel etching process, also known as dual damascene patterning, is both simple and cost-effective. It reliably prevents the formation of fences during the etching process in the region of the polymer intermediate layer. The etching of the oxide layer and the polymer intermediate layer is achieved through a CFARC open process, which offers high selectivity with respect to the photoresist and allows for a lengthened etching time.

Another significant patent is a method for patterning an organic antireflection layer. In this process, an antireflection coating (ARC) polymer layer is patterned using DUV (deep ultraviolet) lithography, followed by an ARC open etching step and subsequent etching of the metal layer. This method results in low resist consumption and steeper resist sidewalls, thanks to the ARC polymer intermediate layer being etched with a CF ARC open process that maintains high selectivity with respect to the photoresist. The gas flows for this process are carefully set within specific ranges to optimize performance.
