A method of manufacturing a high performance MOS device and transistor gate stacks comprises forming a gate dielectric layer over a semiconductor substrate; forming a barrier layer over the gate dielectric layer by an ALD type process; and forming a gate electrode layer over the barrier layer. The method enables the use of hydrogen plasma, high energy hydrogen radicals and ions, other reactive radicals, reactive oxygen and oxygen containing precursors in the processing steps subsequent to the deposition of the gate dielectric layer of the device. The ALD process for forming the barrier layer is performed essentially in the absence of plasma and reactive hydrogen radials and ions. This invention makes it possible to use oxygen as a precursor in the deposition of the metal gates. The barrier film also allows the use of hydrogen plasma in the form of either direct or remote plasma in the deposition of the gate electrode. Furthermore, the barrier film prevents the electrode material from reacting with the gate dielectric material. The barrier layer is ultra thin and, at the same time, it forms a uniform cover over the entire surface of the gate dielectric.

High tensile stress in a deposited layer such as silicon nitride, may be achieved utilizing one or more techniques, employed alone or in combination. High tensile stress may be achieved by forming a silicon-containing layer on a surface by exposing the surface to a silicon-containing precursor gas in the absence of a plasma, forming silicon nitride by exposing said silicon-containing layer to a nitrogen-containing plasma, and then repeating these steps to increase a thickness of the silicon nitride created thereby. High tensile stress may also be achieved by exposing a surface to a silicon-containing precursor gas in a first nitrogen-containing plasma, treating the material with a second nitrogen-containing plasma, and then repeating these steps to increase a thickness of the silicon nitride formed thereby. In another embodiment, tensile film stress is enhanced by deposition with porogens that are liberated upon subsequent exposure to UV radiation or plasma treatment.
