Abstract: A method of single-fin removal for quadruple density fins. A first double density pattern of first sidewall spacers is produced on a semiconductor substrate from first mandrels formed by a first mask using a minimum pitch. A second double density pattern of second sidewall spacers is produced on a layer disposed above the first double density pattern from second mandrels formed by a second mask with a the minimum pitch that is shifted relative to the first mask. A single sidewall spacer is removed from either the first or second double density pattern of first and second sidewall spacers. Sidewall image transfer processes allow the formation of quadruple density fins from which but a single fin is removed.

Abstract: In a method of forming a semiconductor structure, different sections of a dielectric layer are etched at different stages during processing to form a first gate sidewall spacer for a first FET (e.g., a NFET) and a second gate sidewall spacer for a second FET (e.g., a PFET) such that the first and second gate sidewall spacers are symmetric.

Since the gate sidewall spacers of the two FETs are symmetric, the source/drain junctions of the two FETs will also be symmetric. Additionally, due to an etch stop layer formed on the raised source/drain regions of the first FET, but not the second FET, different metal silicides on the raised source/drain regions of the different FETs.

Abstract: A method that forms a structure implants a well implant into a substrate, patterns a mask on the substrate (to have at least one opening that exposes a channel region of the substrate) and forms a conformal dielectric layer on the mask and to line the opening. The conformal dielectric layer covers the channel region of the substrate. The method also forms a conformal gate metal layer on the conformal dielectric layer, implants a compensating implant through the conformal gate metal layer and the conformal dielectric layer into the channel region of the substrate, and forms a gate conductor on the conformal gate metal layer. Additionally, the method removes the mask to leave a gate stack on the substrate, forms sidewall spacers on the gate stack, and then forms source/drain regions in the substrate partially below the sidewall spacers.
