Abstract:
Disclosed is an integrated circuit (IC) structure that incorporates a string of vertical devices. Embodiments of the IC structure include a string of two or more vertical diodes. Other embodiments include a vertical diode/silicon-controlled rectifier (SCR) string and, more particularly, a diode-triggered silicon-controlled rectifier (VDTSCR). In any case, each embodiment of the IC structure includes an N-well in a substrate and, within that N-well, a P-doped region and an N-doped region that abuts the P-doped region. The P-doped region can be anode of a vertical diode and can be electrically connected to the N-doped region (e.g., by a local interconnect or by contacts and metal wiring) such that the vertical diode is electrically connected to another vertical device (e.g., another vertical diode or a SCR with vertically-oriented features). Also disclosed is a manufacturing method that can be integrated with methods of manufacturing vertical field effect transistors (VFETs).

Claim (Index 5):
The integrated circuit structure of  claim 1 ,\n wherein the integrated circuit structure further comprises an N-well in the semiconductor substrate, wherein the P-doped region comprises a P-type epitaxial semiconductor material in a first recess in the N-well, and wherein the N-doped region comprises an N-type epitaxial semiconductor material in a second recess in the N-well and positioned laterally immediately adjacent to the P-type epitaxial semiconductor material, the N-type epitaxial semiconductor material having a higher N-type conductivity level than the N-well.
