Surface roughening process
A process of forming a rough interface in a semiconductor substrate. The process includes the steps of depositing a material on a surface of the substrate, forming a zone of irregularities in the material, and forming a rough interface in the semiconductor substrate by a thermal oxidation of the mat...

Summary: | A process of forming a rough interface in a semiconductor substrate. The process includes the steps of depositing a material on a surface of the substrate, forming a zone of irregularities in the material, and forming a rough interface in the semiconductor substrate by a thermal oxidation of the material and a part of the substrate. Additionally, the surface of the oxidized material may be prepared and the surface may be assembled with a second substrate. |
