Abstract
In one embodiment, a Schottky diode structure comprises a Schottky barrier layer in contact with a semiconductor material through a Schottky contact opening. A conductive ring is formed adjacent the Schottky contact opening and is separated from the semiconductor material by a thin insulating layer. Another insulating layer is formed overlying the structure, and a contact opening is formed therein. The contact opening is wider than the Schottky contact opening and exposes portions of the conductive ring. A Schottky barrier metal is formed in contact with the semiconductor material through the Schottky contact opening, and is formed in further+contact with the conductive ring.
