Our results show that the work function of the laminated metal gate electrodes is significantly different from their bulk electrodes counterpart. Through lamination, a TiTaN/sub x/ alloy gate is formed which exhibits NMOS compatible work function (4.35 eV) with good thermal stability up to 900/spl deg/C. Laminated metal gates consisting of 3 components exhibit pMOS compatible work function (5,0/spl sim/5.2 eV) after 1000/spl deg/C annealing and this value remains unchanged after subsequent thermal processing.
