    摘要: FinFETS and methods for making FinFETs with a recessed stress liner. A method includes providing an SOI substrate with fins, forming a gate over the fins, forming an off-set spacer on the gate, epitaxially growing a film to merge the fins, depositing a dummy spacer around the gate, and recessing the merged epi film. Silicide is then formed on the recessed merged epi film followed by deposition of a stress liner film over the FinFET. By using a recessed merged epi process, a MOSFET with a vertical silicide (i.e. perpendicular to the substrate) can be formed. The perpendicular silicide improves spreading resistance.

    摘要: A low resistance contact is formed to a metal gate or a transistor including a High-κ gate dielectric in a high integration density integrated circuit by applying a liner over a gate stack, applying a fill material between the gate stacks, planarizing the fill material to support high-resolution lithography, etching the fill material and the liner selectively to each other to form vias and filling the vias with a metal, metal alloy or conductive metal compound such as titanium nitride.

    摘要: A semiconductor device which includes fins of a semiconductor material formed on a semiconductor substrate and then a gate electrode formed over and in contact with the fins. An insulator layer is deposited over the gate electrode and the fins. A trench opening is then etched in the insulator layer. The trench opening exposes the fins and extends between the fins. The fins are then silicided through the trench opening. Then, the trench opening is filled with a metal in contact with the silicided fins to form a local interconnect connecting the fins.

    摘要: A finFET device is provided. The finFET device includes a BOX layer, fin structures located over the BOX layer, a gate stack located over the fin structures, gate spacers located on vertical sidewalls of the gate stack, an epi layer covering the fin structures, source and drain regions located in the semiconductor layers of the fin structures, and silicide regions abutting the source and drain regions. The fin structures each comprise a semiconductor layer and extend in a first direction, and the gate stack extends in a second direction that is perpendicular. The gate stack comprises a high-K dielectric layer and a metal gate, and the epi layer merges the fin structures together. The silicide regions each include a vertical portion located on the vertical sidewall of the source or drain region.
