Abstract:
Semiconductor devices and methods for forming the devices with fin contacts. One method includes, for instance: obtaining a wafer with at least one isolation region; forming at least one fin on the wafer; forming at least one sacrificial contact; forming at least one sacrificial gate; etching to recess the at least one fin; growing an epitaxial material over the at least one fin; performing replacement metal gate to the at least one sacrificial gate; depositing an interlayer dielectric layer; and forming at least one fin contact. An intermediate semiconductor device is also disclosed.
