    Abstract: A method for fabricating an integrated circuit includes providing a semiconductor substrate including a gate electrode structure thereon and sidewall spacers along sidewalls of the gate electrode structure to a first height along the sidewalls, forming a planarizing carbon-based polymer layer over the gate electrode structure and over the sidewall spacers, and etching a portion of the optical planarization layer to expose a top portion the gate electrode structure. Further, the method includes etching an upper portion of the sidewall spacers selective to the gate electrode structure so as to expose the sidewalls of the upper portion of the gate electrode structure and depositing a silicide-forming material over the top portion of the gate electrode structure and the sidewalls of the upper portion of the gate electrode structure. Still further, the method includes annealing the silicide-forming material.

    Abstract: When forming field-effect transistors, a common problem is the formation of a Schottky barrier at the interface between a metal thin film in the gate electrode and a semiconductor material, typically polysilicon, formed thereupon. Fully silicided gates are known in the state of the art, which may overcome this problem. However, formation of a fully silicided gate is hindered by the fact that silicidation of the source and drain regions and of the gate electrode are normally performed simultaneously. The claimed method proposes two consecutive silicidation processes which are decoupled with respect to each other. During the first silicidation process, a metal silicide is formed forming an interface with the source and drain regions and without affecting the gate electrode. During the second silicidation, a metal silicide layer having an interface with the gate electrode is formed, without affecting the transistor source and drain regions.

    Abstract: In aspects of the present invention, a method of forming a semiconductor device is disclosed, wherein amorphous regions are formed at an early stage during fabrication and the amorphous regions are conserved during subsequent processing sequences, and an intermediate semiconductor device structure with amorphous regions are provided at an early stage during fabrication. Herein a gate structure is provided over a semiconductor substrate and amorphous regions are formed adjacent the gate structure. Source/drain extension regions or source/drain regions are formed in the amorphous regions. In some illustrative embodiments, fluorine may be implanted into the amorphous regions. After the source/drain extension regions and/or the source/drain regions are formed, a rapid thermal anneal process is performed.
