Title: Pierre Tchoulfian: Innovator in Semiconductor Technology
Introduction
Pierre Tchoulfian is a notable inventor based in Grenoble, France. He has made significant contributions to the field of semiconductor technology, holding a total of 6 patents. His work focuses on innovative methods and devices that enhance the performance and efficiency of optoelectronic components.
Latest Patents
One of Tchoulfian's latest patents is a method of forming a dielectric collar for semiconductor wires. This method involves providing a layers stack and a semiconductor wires (SW) layer on top of the stack. It includes forming a base layer at the lower part of the SW and a capping layer at the upper part of the SW. The base layer is parallel to the basal plane and consists of a dielectric material surrounding the lower part of the SW. The capping layer follows the contour of the SW and also includes a dielectric material surrounding the upper part of the SW. The base and capping layers have specific thicknesses, and the method employs anisotropic etching to remove dielectric material at the top part of the SW while retaining it in the lower part.
Another significant patent involves an optoelectronic device with light-emitting diodes that incorporate a doped region based on aluminium and gallium nitride. This device features a substrate and wire-shaped light-emitting diodes that are elongated along a longitudinal axis. Each diode has a doped first region that includes a central first segment based on gallium nitride and an external second segment based on aluminium and gallium nitride. This innovative design enhances the functionality and efficiency of the light-emitting diodes.
