    摘要: Barrier layers for conductive features and methods of formation thereof are disclosed. A first barrier material is deposited on top surfaces of an insulating material, and a second barrier material is deposited on sidewalls of the insulating material, wherein the second barrier material is different than the first barrier material. The first barrier material induces grain growth of a subsequently deposited conductive material at a first rate, and the second barrier material induces grain growth of the conductive material at a second rate, wherein the second rate is slower than the first rate.

    摘要: A method for fabricating a field-effect transistor with local source/drain insulation. The method includes forming and patterning a gate stack with a gate layer and a gate dielectric on a semiconductor substrate; forming source and drain depressions at the gate stack in the semiconductor substrate; forming a depression insulation layer at least in a bottom region of the source and drain depressions; and filling the at least partially insulated source and drain depressions with a filling layer for realizing source and drain regions. Further, the step of forming source and drain depressions at the gate stack in the semiconductor substrate includes that first depressions are formed for realizing channel connection regions in the semiconductor substrate, spacers are formed at the gate stack, and second depressions are formed using the spacers as a mask in the first depressions and in the semiconductor substrate.
