Title: Innovations by Guillaume Chabanne

Introduction

Guillaume Chabanne is a notable inventor based in Le Touvet, France. He has made significant contributions to the field of semiconductor technology, holding a total of five patents. His work focuses on advanced methods for fabricating semiconductor materials, which are crucial for various electronic applications.

Latest Patents

One of his latest patents is a method for fabricating a strained semiconductor-on-insulator substrate. This innovative method involves bonding a donor substrate to a receiving substrate with a dielectric layer at the interface. The donor substrate consists of a monocrystalline carrier substrate, an intermediate etch-stop layer, and a monocrystalline semiconductor layer. The process includes transferring the monocrystalline semiconductor layer from the donor substrate to the receiving substrate. Trench isolations are then formed to cut a portion from a layer stack that includes the transferred monocrystalline semiconductor layer, the dielectric layer, and the strained semiconductor material layer. This cutting operation results in the relaxation of strain in the strained semiconductor material and applies strain to the transferred monocrystalline semiconductor layer. Prior to the cutting operation, a portion of the carrier substrate is selectively etched with respect to the intermediate layer, and the intermediate layer is selectively etched with respect to the monocrystalline semiconductor layer.
