Devices with contact-to-gate shorting through conductive paths between fins and fabrication methods

Abstract

Semiconductor devices and methods of fabricating the semiconductor devices for forming conductive paths between fins for contact-to-gate shorting. One method includes, for instance: obtaining wafer with a substrate, at least one fin, at least one hard mask, and an oxide layer; etching the oxide layer to reveal at least one of a portion of the hard masks; forming sacrificial pillars over the substrate; forming sacrificial gates, wherein at least one sacrificial gate contacts at least one sacrificial pillar; growing an epitaxial layer between the at least one sacrificial gate and the at least one sacrificial pillar; starting a RMG process on the sacrificial gates; etching to remove the sacrificial pillars and form pillar openings; and completing the RMG process to fill the pillar openings and the gate openings with a metal.
