Abstract:
Vertical gate all around (VGAA) devices and methods of manufacture thereof are described. A method for manufacturing a VGAA device includes: exposing a top surface and sidewalls of a first portion of a protrusion extending from a doped region, wherein a second portion of the protrusion is surrounded by a gate stack; and enlarging the first portion of the protrusion using an epitaxial growth process.

Claim (Index 8):
A device comprising:\n a first doped region over a semiconductor substrate, the first doped region having a first conductivity; a first protrusion extending from the first doped region; a second doped region laterally adjacent the first doped region, the second doped region having a second conductivity different from the first conductivity; a second protrusion extending from the second doped region; an isolation feature disposed between the first doped region and the second doped region, the isolation feature comprising an insulating material; a first gate stack surrounding a first portion of the first protrusion, wherein a second portion of the first protrusion is free from the first gate stack; a second gate stack surrounding a first portion of the second protrusion, wherein a second portion of the second protrusion is free from the second gate stack; a spacer having a first sidewall and a second sidewall, the first sidewall contacting a sidewall of the first gate stack, and the second sidewall contacting a sidewall of the second gate stack; a first epitaxial semiconductor material surrounding the second portion of the first protrusion, the first epitaxial semiconductor material having a hexagonal shape in top-down view; and a second epitaxial semiconductor material surrounding the second portion of the second protrusion, the second epitaxial semiconductor material having a hexagonal shape in top-down view.
