    摘要: A method of protecting a sensitive layer from harsh chemistries. The method includes forming a first sensitive layer, forming a second layer upon the first layer, then forming a third layer over the second layer. The third layer is utilized as a mask during patterning of the second layer. During patterning, however, the second layer is only partially etched, thus leaving a buffer layer overlying the first layer. The third layer is completely removed while the buffer layer protects the first layer from the harsh chemicals that are utilized to remove the third layer. Then, the buffer layer is carefully removed down to the surface of the first layer.

    摘要: A high-K thin film patterning solution is disclosed to address structural and process limitations of conventional patterning techniques. Subsequent to formation of gate structures adjacent a high-K dielectric layer, a portion of the high-K dielectric layer material is reduced, preferably via exposure to hydrogen gas, to form a reduced portion of the high-K dielectric layer. The reduced portion may be selectively removed utilizing wet etch chemistries to leave behind a trench of desirable geometric properties.
