Title: Rakesh Kumar: Innovator in Semiconductor Technology
Introduction
Rakesh Kumar is a notable inventor based in Escondido, California. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approaches to integrated circuit fabrication.
Latest Patents
One of Rakesh Kumar's latest patents is a method for mass producing miniature field effect transistors. This method involves implanting dopant atoms of a first conductivity type into a semiconductor substrate to create a channel region with a high dopant density at a specific depth. This technique effectively eliminates reachthrough in the channel while maintaining the threshold voltage. Additionally, dopant atoms of a second conductivity type are implanted to form source and drain regions, minimizing the radius of curvature and depletion width at the junctions. The process also includes forming a patterned insulating layer at low temperatures to prevent the diffusion of implanted dopant atoms.
Another significant patent by Kumar relates to the fabrication of integrated circuits using only ion implantation. This method allows for the formation of a buried collector in a bipolar integrated circuit with a high density of dopant species. The process is streamlined by activating certain implanted species during a single high-temperature annealing step. A pre-aligned mask is utilized to create self-aligned base contacts, collector contacts, and emitters, reducing the number of masking steps required.
