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 9):
The integrated circuit structure of  claim 6 , further comprising:\n an additional N-well in the semiconductor substrate; an isolation region in the semiconductor substrate and positioned laterally between the N-well and the additional N-well; and an additional pair of devices comprising:\n an additional first device comprising:\n an additional first anode in the additional N-well; \n an additional first semiconductor fin having a lower end immediately adjacent to the additional first anode and an upper end opposite the lower end; and \n an additional first cathode immediately adjacent to the upper end of the additional first semiconductor fin; and \n \n an additional second device comprising:\n an additional second cathode in the additional N-well and positioned laterally immediately adjacent to the additional first anode; \n an additional second semiconductor fin having a lower end immediately adjacent to the additional second cathode and an upper end opposite the lower end; and \n an additional second anode immediately adjacent to the upper end of the additional second semiconductor fin, \n \n wherein the additional first anode and the additional second cathode are electrically connected.
