  • Patent number: 10146900
    Abstract: 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.

  • Patent number: 9859891
    Abstract: A MOS device may include a first logic component with a first input located on a second track and a first output located on the third track. The MOS device may include a second logic component with a second input located on the fourth track and a second output located on a fifth track. For example, the MOS device includes a first interconnect on a Mx layer that is coupled to the first input on the second track. In another example, the MOS device includes a second interconnect on the Mx layer that is coupled to the first output on the third track. The MOS device includes a third interconnect on a My layer that is coupled to the second input on the fourth track. Still further, the MOS device includes a fourth interconnect on the My layer that is coupled to the second output on the fifth track.

  • Patent number: 9490245
    Abstract: A MOS device for reducing an antenna effect is provided. The MOS device includes a diode including a first nMOS transistor having a first nMOS transistor source, a first nMOS transistor drain, a first nMOS transistor gate, and an nMOS transistor body. The nMOS transistor body is coupled to a first voltage source and is an anode of the diode. The first nMOS transistor source, the first nMOS transistor drain, and the first nMOS transistor gate are coupled together and are a cathode of the diode. The MOS device further includes an interconnect extending between a driver output and a load input. The interconnect is coupled to the cathode of the diode. The interconnect may extend on one metal layer only between the driver output and the load input.
