Title: Innovations of John E Campbell
Introduction
John E Campbell is a notable inventor based in Plano, TX (US). He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approaches to integrated circuit design.
Latest Patents
One of his latest patents is titled "Shallow trench isolation planarization using self aligned isotropic etch." This method involves forming planar isolation structures for integrated circuits by creating an etch barrier over the isolation fill material. An etch back is performed to remove material above unetched portions of the substrate, allowing the exposed fill material to be etched and planarized to form a planar isolation structure. Another significant patent is "Method for trench isolation of semiconductor devices." This method describes a process for removing excess oxide from active areas after shallow trench isolation, without the need for chemical-mechanical polishing. A nitride mask is utilized to protect active areas during the etch of isolation trenches, and the trenches are filled with oxide using high-density plasma deposition, which simultaneously etches to provide a sloping contour around the isolation trenches.
