  • Method of passivating a semiconductor substrate
    Patent number: 5908316
    Abstract: A method of passivating a semiconductor substrate includes singulating (13) a semiconductor substrate (23) from a semiconductor wafer, coupling (14) a heatsink (21) to the semiconductor substrate (23), etching (15) the semiconductor substrate (23) in a chamber of an etch tool, and passivating (17) the semiconductor substrate (23) with an oxide layer (31). The semiconductor substrate (23) is kept in the chamber of the etch tool from the etching (15) step through the passivating (17) step. The etching (15) of the semiconductor substrate (23) does not substantially etch the heatsink (21), and the passivating (17) of the semiconductor substrate (23) does not substantially passivate the heatsink (21).
