CMOS inverter (a NOT logic gate). Complementary metal–oxide–semiconductor (CMOS, pronounced "sea-moss ", / s iː m ɑː s /, /-ɒ s /) is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions.

Layout view of a simple CMOS operational amplifier. In integrated circuit design, integrated circuit (IC) layout, also known IC mask layout or mask design, is the representation of an integrated circuit in terms of planar geometric shapes which correspond to the patterns of metal, oxide, or semiconductor layers that make up the components of the integrated circuit.
The technology used a 32 nm SOI process, two CPU cores per module, and up to four modules, ranging from a quad-core design costing approximately US$130 to a $280 eight-core design. Ambarella Inc. announced the availability of the A7L system-on-a-chip circuit for digital still cameras, providing 1080p60 high-definition video capabilities in ...
In December 2021, Vertical-Transport FET (VTFET) CMOS logic transistor design with a vertical nanosheet was demonstrated at sub-45 nm gate pitch. [49] In May 2022, imec presented a process technology roadmap which extends the current biannual cadence of node introduction and square-root-of-two node naming rule to 2036. The roadmap ends with ...
A Process design kit (PDK) may be provided by the foundry and it may include the standard cell library as well as the specifications of the cells, and tools to verify the fabless company's design against the design rules specified by the foundry as well as simulate it using the foundry's cells. PDKs may be provided under non-disclosure agreements.
Scaling of isolation with transistor size. Isolation pitch is the sum of the transistor width and the trench isolation distance. As the isolation pitch shrinks, the narrow channel width effect becomes more apparent. The shallow trench isolation fabrication process of modern integrated circuits in cross-sections.
Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining millions or billions of MOS transistors onto a single chip. VLSI began in the 1970s when MOS integrated circuit (metal oxide semiconductor) chips were developed and then widely adopted, enabling complex semiconductor and telecommunications technologies.
English: The physical layout of a CMOS NAND circuit. The larger regions of N-type diffusion and P-type diffusion are part of the transistors. The two smaller regions on the left are taps to prevent latchup.
