Latest Patents
Montel's latest patents include a "Transit time diode with an input structure formed by a matrix of micropoints." This invention utilizes the transit time of electrical charge carriers in a semiconductor medium, featuring an input structure made up of microscopic contacts. The matrix consists of contacts that are separated by an insulating layer, with diameters ranging from 0.5 to 5 micrometers and distances between the closest contacts of 0.5 to 15 micrometers. The materials used for the contacts include metal, low resistivity alloys, or heavily doped semiconductor materials. This innovative structure enhances efficiency by reducing avalanche voltage or improving injection through the tunnel effect.
Another significant patent is the "Method of manufacturing metal-semiconductor contacts exhibiting high contact performance." This method aims to virtually eliminate contact resistances, particularly at very high frequencies, such as in source and drain contacts of field effect transistors. The process involves creating a matrix of depressions or 'dishes' that are 1 to 6 microns in diameter, separated by intervals of a few microns. The method includes opening windows in an insulating layer through etching, carving angular profiles in the bottom of the dishes via ion machining, and finally depositing a metal layer that envelops the matrix.
