摘要： A method for forming silicide contacts in integrated circuits (ICs) is described. A spacer pull-back etch is performed during the salicidation process to reduce the stress between the spacer and source/drain silicide contact at the spacer undercut. This prevents the propagation of surface defects into the substrate, thereby minimizing the occurrence of silicide pipe defects. The spacer pull-back etch can be performed after a first annealing step to form the silicide contacts.

摘要： A composite etch stop layer which comprises primary and secondary stop layers is used to form contacts in a dielectric layer to contact regions in a substrate. The secondary etch stop layer includes a high-k dielectric material to achieve high etch selectivity with the dielectric layer during contact formation. The secondary stop layer is removed to expose the contact regions. Removal of the secondary stop layer is achieved with high selectivity to the materials therebelow.

摘要： A transistor having an epitaxial channel and a method for fabricating a semiconductor device having an epitaxial channel, the method including forming a hardmask on a substrate and forming an opening in the hardmask. The opening is geometrically characterized by a long dimension and a short dimension, and the opening is arranged in a predetermined manner relative to the channel region of a transistor. An epitaxial material is formed in the opening that induces strain in substrate regions proximate to the epitaxial material. The epitaxial material is confined to the opening, such that an epitaxial channel is formed. A transistor is fabricated in proximity to the epitaxial channel, such that the strain induced in the substrate provides enhanced transistor performance. By confining the epitaxial material to a predefined channel in the substrate, plastic strain relaxation of the epitaxial material is minimized and a maximum amount of strain is induced in the substrate.
