  • Publication number: 20210217878
    Abstract: A diffused field-effect transistor (FET) is disclosed. The diffused FET is dually optimized in voltage resistance by incorporating both a trench isolation structure and a thick second oxide layer and thus has a more significantly improved breakdown voltage. With the thick second oxide layer ensuring suitable voltage resistance of the transistor device, its on-resistance can be reduced either by reducing the size of the trench isolation structure or increasing an ion dopant concentration of a drift region. As such, a good tradeoff between voltage resistance and on-resistance is achievable.
