Latest Patents

Yvonne H. Keller holds a patent for a method of fabricating an ultra-thin active region. This method is designed to retard the diffusion of a dopant from a center active region into adjacent regions. The center active region is epitaxially formed by selectively increasing and decreasing the introduction of diffusion-suppressing material, preferably germanium, into a semiconductor material, preferably silicon. This technique minimizes outdiffusion of a dopant, which is crucial for achieving a thinner and more highly doped active region.
