Latest Patents
One of his latest patents is titled "Systems and methods for two-sided etch of a semiconductor substrate." This invention involves a system and method for etching both sides of a semiconductor substrate. Reactive species are generated and directed toward the substrate for processing. A diverter is strategically positioned between the generation chamber and the substrate, allowing a portion of the reactive species to process the front of the substrate while another portion is diverted to the backside. Additionally, a flow restricter is placed between the substrate and the exhaust system to enhance the residence time of reactive species adjacent to the backside. Another significant patent is the "Downstream surface cleaning process," which provides systems and methods for selectively removing unwanted material from a semiconductor wafer's surface without damaging the underlying portions. This invention utilizes reactive species from a plasma source to effectively remove residues remaining after metal etching on a silicon wafer.
