Abstract

A semiconductor device and a method of fabricating the semiconductor device are disclosed. The method includes forming a fin structure having a first fin portion and a second fin portion, forming a first dielectric layer on the substrate and on sidewalls of the first fin portion, forming a second dielectric layer on the first dielectric layer, performing an oxidation process on the second fin portion to form an oxide layer, depositing a gate dielectric layer on the oxide layer and on the second dielectric layer, depositing a gate conductive layer on the gate dielectric layer, and forming an isolation structure extending through the gate conductive layer, the gate dielectric layer, and the second dielectric layer.
