RECESSED TRANSISTOR TERMINAL VIA JUMPERS
Abstract:
Integrated circuit (IC) devices include transistors with gate, source and drain contact metallization, some of which are jumpered together by a metallization that is recessed below a height of other metallization that is not jumpered. The jumper metallization may provide a local interconnect between terminals of one transistor or adjacent transistors, for example between a gate of one transistor and a source/drain of another transistor. The jumper metallization may not induce the same pitch constraints faced by interconnect line metallization levels employed for more general interconnection. In some examples, a static random-access memory (SRAM) bit-cell includes a jumper metallization joining two transistors of the cell to reduce cell height for a given feature patterning capability.
