Latest Patents

One of his latest patents is for a Drain Extended Transistor. This invention describes examples that include integrated circuits, drain extended transistors, and fabrication methods. In this patent, an oxide structure is formed over a drift region of a semiconductor substrate. A shallow implantation process is performed using a first mask that exposes the oxide structure and a first portion of the semiconductor substrate to form a first drift region portion for connection to a body implant region. A second drift region portion is implanted in the semiconductor substrate under the oxide structure by a second implantation process using the first mask at a higher implant energy.

Another notable patent is related to Hydrogen Ventilation of CMOS Wafers. This integrated circuit includes a semiconductor substrate with a device die that contains transistors configured to execute an electrical function. A first interconnect layer of the device die is designed to route electrical signals or power to the terminals of the transistors. An interlevel dielectric (ILD) layer is located over the interconnect layer, with a metal electrode situated above the ILD layer. A dielectric barrier layer is positioned between the ILD layer and the metal electrode, while a scribe seal surrounds the device die. The patent also details a first opening within the dielectric barrier layer that surrounds the metal electrode, along with second and third openings located between the first opening and the scribe seal.
