Abstract:
One embodiment provides a method of integrating a planar field-effect transistor (FET) with a vertical FET. The method comprises masking and etching a semiconductor of the vertical FET to form a fin, and providing additional masking, additional etching, doping and depositions to isolate a bottom source/drain (S/D) region. A dielectric is formed on the bottom S/D region to form a spacer. The method further comprises depositing gate metals, etching a vertical gate for the vertical FET and a planar gate for the planar FET using a shared gate mask, depositing dielectric, etching the dielectric to expose one or more portions of the fin, growing epitaxy on a top S/D region, masking and etching S/D contact openings for the bottom S/D region, forming silicide regions in S/D regions, depositing contact metal in the silicide regions to form contacts, and planarizing the contacts.

Claim (Index 1):
A method comprising:\n determining a process flow for integrating a long gate length device into a short gate length device; modifying the process flow to include one or more modifications; and manufacturing a semiconductor structure comprising the long gate length device and the short gate length device by integrating the long gate length device into the short gate length device based on the modified process flow; wherein the one or more modifications comprise masking a spacer in a planar region and re-using the spacer as a gate dielectric for the planar region.
