HYBRID DIFFUSION STANDARD LIBRARY CELLS, AND RELATED SYSTEMS AND METHODS

摘要

Hybrid diffusion standard library cells, and related systems and methods are disclosed. The hybrid diffusion standard library cells may be fabricated with reduced costs because masks corresponding to fixed base layers remain constant across integrated circuit (IC) devices. In one aspect, a hybrid diffusion standard library cell is provided. The hybrid diffusion standard library cell employs multiple diffusion regions, wherein a break region separates at least two of the multiple diffusion regions. The hybrid diffusion standard library cell includes one or more MEOL interconnects at fixed locations that are configured to connect transistors to a first metal layer. The hybrid diffusion standard library cell includes at least one transistor. Including the break region between multiple diffusion regions helps to limit the locations of the fixed MEOL interconnects, which limits possible locations for base level transistors and fixes the base layer design.

1. A standard library cell, comprising:
at least one transistor; a plurality of diffusion regions, wherein at least one diffusion region of the plurality of diffusion regions corresponds to the at least one transistor; one or more break regions separating at least two diffusion regions of the plurality of diffusion regions; and one or more fixed middle-end-of-line (MEOL) interconnects configured to connect the at least one transistor to a first metal layer.
