Abstract:
A method is presented for tuning work functions of transistors. The method includes forming a work function stack over a semiconductor substrate, depositing a germanium oxide layer and a barrier layer over the work function stack, and annealing the germanium oxide layer to desorb oxygen therefrom to trigger oxidation of at least one conducting layer of the work function stack. The work function stack includes three layers, that is, a first layer being a TiN layer, a second layer being a titanium aluminum carbon (TiAlC) layer, and a third layer being a second TiN layer.

Claim (Index 7):
The method of  claim 1 , wherein the first region includes high n-type threshold voltage (nVt) devices and low p-type threshold voltage (pVt) devices.
