Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An electrical device comprising:
a first vertical field effect transistor (VFET) including a first source/drain region present on a supporting substrate, a first channel region in direct contact with the first source/drain region and a common source/drain region;
a second vertical field effect transistor including the common source/drain region, a second channel region present on the common/source drain region, and a second source/drain region present on the second channel region, wherein the first and second vertical field effect transistors (VFETs) are vertically stacked upon one another the first channel region, the common source/drain region, the second channel region and the second source/drain region present within a fin structure, the first and second vertical field effect transistors being connected by the common source/drain region; and
a gate contact is in direct contact with each of a first gate structure to the first channel region of the first vertical field effect transistor and a second gate structure to the second channel region of the second vertical field effect transistor.
