Abstract:
A vertical SRAM cell includes a first (1 st ) inverter having a 1 st  common gate structure operatively connecting channels of a 1 st  pull-up (PU) and a 1 st  pull-down (PD) transistor. A 1 st  metal contact electrically connects bottom source/drain (S/D) regions of the 1 st  PU and 1 st  PD transistors. A second (2 nd ) inverter has a 2 nd  common gate structure operatively connecting channels of a 2 nd  PU and a 2 nd  PD transistor. A 2 nd  metal contact electrically connects bottom S/D regions of the 2 nd  PU and 2 nd  PD transistors. A 1 st  cross-coupled contact electrically connects the 2 nd  common gate structure to the 1 st  metal contact. The 2 nd  common gate structure entirely surrounds a perimeter of the 1 st  cross-coupled contact. A 2 nd  cross-coupled contact electrically connects the 1 st  common gate structure to the 2 nd  metal contact. The 1 st  common gate structure entirely surrounds a perimeter of the 2 nd  cross-coupled contact.

Claim (Index 14):
The method of  claim 12 , comprising:\n forming upper S/D regions on an upper end of each channel; disposing a dielectric layer over the SRAM cell structure; etching upper S/D trenches into the dielectric layer to expose a portion of the upper S/D regions; forming CA contacts into the upper S/D trenches, the CA contacts each having a lower surface disposed at a lower surface height above the substrate; and recessing an upper surface of the cross-coupled contacts to a recessed height above the substrate, the recessed height of the cross-coupled contacts being below the lower surface height of the CA contacts.
