Latest Patents

Among his latest patents, one notable invention is the "Metal silicide channel stoppers for integrated circuits." This patent discloses the use of metal silicide contacts, such as Pt-Si, in boron lightly doped P.sup.- type silicon. This innovative approach replaces the traditional P.sup.+ implanted or diffused channel stoppers, particularly benefiting polyimide filled deep trench isolated integrated circuits. The trench sidewalls are coated with an insulating material, which is removed from the trench bottom during the contact etch step. The Pt-Si is formed at the bottom of the trenches simultaneously with the device contacts.

Another significant patent is the "Method for making metal contact studs between first level metal and." This method outlines the steps to create metal device contact studs between regions of a semiconductor device, such as an NPN vertical bipolar transistor, and the first level metal. The studs overlap both a contact region and an adjacent polyimide-filled trench, enhancing the efficiency of semiconductor device manufacturing.
