    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 method is provided for fabricating a finFET device. Fin structures are formed over a BOX layer. The fin structures include a semiconductor layer and extend in a first direction. A gate stack is formed on the BOX layer over the fin structures and extending in a second direction. The gate stack includes a high-K dielectric layer and a metal gate. Gate spacers are formed on sidewalls of the gate stack, and an epi layer is deposited to merge the fin structures. Ions are implanted to form source and drain regions, and dummy spacers are formed on sidewalls of the gate spacers. The dummy spacers are used as a mask to recess or completely remove an exposed portion of the epi layer. Silicidation forms silicide regions that abut the source and drain regions and each include a vertical portion located on the vertical sidewall of the source or drain region.

    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.
