Patent ID: 7045376

Claim:
A method of passivating a semiconductor device, said method comprising: placing a semiconductor device in a chamber, the semiconductor device having a first type of transistors and a second type of transistors; introducing a first passivating gas and a second passivating gas into the chamber; and heating the semiconductor device to a temperature for a period sufficient to passivate the semiconductor device; wherein the first passivating gas is introduced into the chamber and the semiconductor device is heated to a temperature for a period sufficient to passivate the first type of transistors, and then the second passivating gas is introduced into the chamber and the semiconductor device is heated to a temperature for a period sufficient to passivate the second type of transistors; and the first passivating gas is drained out of the chamber by introducing the second passivating gas into the chamber and the pressure of the chamber is greater than 1 atmosphere.
