Patent ID: 7241691

Claim:
A method for forming a metal electrode comprising: providing a high k dielectric stack with an exposed surface; contacting the exposed surface of the high k dielectric stack with a vapor of a metal oxide wherein the metal oxide comprises a material selected from the group consisting of RuO x , IrO y , ReO z , MoO a , WO b , VO x , and PdO c ; where each of x, y, z, a, b, and c are real numbers; and contacting the exposed surface of the dielectric stack with a vapor of an additive selected from the group consisting of SiO 2 , Al 2 O 3 , HfO 2 , ZrO 2 , MgO, SrO, BaO, Y 2 O 3 , La 2 O 3 , and TiO 2 , whereby contacting the exposed surface of the dielectric stack with the vapor of the metal oxide and the vapor of the additive forms an electrode and wherein the additive is present at an amount between about 1% to about 50% by atomic percent in the electrode.
