Enhancing Schottky breakdown voltage (BV) without affecting an integrated MOSFET-Schottky device layout |
摘要 |
This invention discloses a semiconductor power device that includes an active cell area having a plurality of power transistor cells and a junction barrier Schottky (JBS) area. The semiconductor power device includes the JBS area that further includes a plurality of Schottky diodes each having a PN junction disposed on an epitaxial layer near a top surface of a semiconductor substrate wherein the PN junction further includes a counter dopant region disposed in the epitaxial layer for reducing a sudden reversal of dopant profile near the PN junction for preventing an early breakdown in the PN junction. |
