SEMICONDUCTOR DEVICE FORMED HAVING A METAL LAYER FOR CONDUCTING THE DEVICE CURRENT AND FOR HIGH CONTRAST MARKING AND METHOD THEREOF

摘要

A power semiconductor device including a semiconductor die having electrically active first and second surfaces. A mark is located on the second surface configured to facilitate identification of the device and a metal layer is formed over the second surface of the semiconductor die and over the mark. The metal layer is configured to conduct a current of the device and to allow the mark to be visible for identification purposes.
