Abstract:
Exemplary embodiments for an exemplary dual transmission gate and various exemplary integrated circuit layouts for the exemplary dual transmission gate are disclosed. These exemplary integrated circuit layouts represent double-height, also referred to as double rule, integrated circuit layouts. These double rule integrated circuit layouts include a first group of rows from among multiple rows of an electronic device design real estate and a second group of rows from among the multiple rows of the electronic device design real estate to accommodate a first metal layer of a semiconductor stack. The first group of rows can include a first pair of complementary metal-oxide-semiconductor field-effect (CMOS) transistors, such as a first p-type metal-oxide-semiconductor field-effect (PMOS) transistor and a first n-type metal-oxide-semiconductor field-effect (NMOS) transistor, and the second group of rows can include a second pair of CMOS transistors, such as a second PMOS transistor and a second NMOS transistor. These exemplary integrated circuit layouts disclose various configurations and arrangements of various geometric shapes that are situated within an oxide diffusion (OD) layer, a polysilicon layer, a metal diffusion (MD) layer, the first metal layer, and/or a second metal layer of a semiconductor stack. In the exemplary embodiments to follow, the various geometric shapes within the first metal layer are situated within the multiple rows of the electronic device design real estate and the various geometric shapes within the OD layer, the polysilicon layer, the MD layer, and/or the second metal layer are situated within multiple columns of the electronic device design real estate.
