摘要： The present invention provides structures and methods for providing facets with different crystallographic orientations than what a semiconductor substrate normally provides. By masking a portion of a semiconductor surface and exposing the rest to an anisotripic etch process that preferentially etches a set of crystallographic planes faster than others, new facets with different surface orientations than the substrate orientation are formed on the semiconductor substrate. Alternatively, selective epitaxy may be utilized to generate new facets. The facets thus formed are joined to form a lambda shaped profile in a cross-section. The electrical properties of the new facets, specifically, the enhanced carrier mobility, are utilized to enhance the performance of transistors. In a transistor with a channel on the facets that are joined to form a lambda shaped profile, the current flows in the direction of the ridge joining the facets avoiding any inflection in the direction of the current.

摘要： A reliable and mechanical strong interconnect structure is provided that does not include gouging features in the bottom of the an opening, particularly at a via bottom. Instead, the interconnect structures of the present invention utilize a Co-containing buffer layer that is selectively deposited on exposed surfaces of the conductive features that are located in a lower interconnect level. The selective deposition is performed through at least one opening that is present in a dielectric material of an upper interconnect level. The selective deposition is performed by electroplating or electroless plating. The Co-containing buffer layer comprises Co and at least one of P and B. W may optionally be also present in the Co-containing buffer layer.

摘要： Semiconductor wiring structures including a dielectric layer having a metal wiring line therein, a via extending downwardly from the metal wiring line, a metal cap layer over the metal wiring line, and a local dielectric cap positioned within a portion of the metal cap layer and in contact with the metal wiring line and a related method are disclosed. The local dielectric cap represents an intentionally created weak point in the metal wiring line of a dual-damascene interconnect, which induces electromigration (EM) voiding in the line, rather than at the bottom of a via extending downwardly from the metal wiring line. Since the critical void size in line fails, especially with metal cap layer (liner) redundancy, is much larger than that in via fails, the EM lifetime can be significantly increased.
