HYBRID DIFFUSION STANDARD LIBRARY CELLS, AND RELATED SYSTEMS AND METHODS

摘要

Hybrid diffusion standard library cells for engineering change orders (ECO), 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. The hybrid diffusion standard library cell includes at least one transistor and multiple diffusion regions (102(1-4)), wherein a break region (104) separates at least two of the multiple diffusion regions. The hybrid diffusion standard library cell includes one or more MEOL interconnects (106(1-19)) at fixed locations that are configured to connect transistors to a first metal layer. One of the interconnects (106(17)) may be disposed in the break region. 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.
