  • Integrated devices with optical and electrical isolation and method for making
    Patent number: 7285433
    Abstract: The invention is directed to a method for optical and electrical isolation between adjacent integrated devices. The method comprises the steps of forming at least one trench through an exposed surface of a semiconductor wafer by removing a portion of the semiconductor wafer material, forming an electrically insulating layer on the sidewalls and the bottom of the at least one trench, filling the at least one trench by conformally depositing an optically isolating material, and planarizing the semiconductor wafer surface by removing the portion of the optically isolating material above the exposed surface of the semiconductor wafer.
