Abstract:
A method includes forming a gate stack on a middle portion of s semiconductor fin, and forming a first gate spacer on a sidewall of the gate stack. After the first gate spacer is formed, a template dielectric region is formed to cover the semiconductor fin. The method further includes recessing the template dielectric region. After the recessing, a second gate spacer is formed on the sidewall of the gate stack. The end portion of the semiconductor fin is etched to form a recess in the template dielectric region. A source/drain region is epitaxially grown in the recess.

Claim (Index 17):
A device of integrated circuits, the device comprising:\n an isolation region; a Fin Field-Effect Transistor (FinFET) comprising:\n a semiconductor fin higher than a top surface of the isolation region; \n a gate dielectric on a sidewall and a top surface of the semiconductor fin; \n a first gate spacer comprising a horizontal leg and a vertical leg connecting to an end of the horizontal leg, wherein a first sidewall of the first gate spacer contacts the gate dielectric; \n a template dielectric region over and contacting a top surface of the horizontal leg; and \n a second gate spacer over and contacting the template dielectric region; and \n a contact etch stop layer over and contacting the template dielectric region, wherein the contact etch stop layer and the second gate spacer form interfaces with the template dielectric region, and the interfaces are lower than a top surface of the template dielectric region.
