Abstract: Approaches for forming a FinFET device using double patterning memorization techniques are provided. Specifically, a device will initially be formed by defining a set of fins, depositing a poly-silicon layer, and depositing a hardmask. Thereafter, a front end of the line (FEOL) lithography-etch, lithography-etch (LELE) process will be performed to form a set of trenches in the device. The set of trenches will be filled with an oxide layer that is subsequently polished. Thereafter, the device is selectively etched to yield a (e.g., poly-silicon) gate pattern.
