Illustration of FEOL (device generation in the silicon, bottom) and BEOL (depositing metalization layers, middle part) to connect the devices. CMOS fabrication process. The front end of line (FEOL) is the first portion of IC fabrication where the individual components (transistors, capacitors, resistors, etc.) are patterned in a semiconductor substrate. [1]
Simplified illustration of the process of fabrication of a CMOS inverter on p-type substrate in semiconductor microfabrication. Each etch step is detailed in the following image. The diagrams are not to scale, as in real devices, the gate, source, and drain contacts are not normally located in the same plane. Detail of an etch step.
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.

The shallow trench isolation fabrication process of modern integrated circuits in cross-sections. Shallow trench isolation (STI), also known as box isolation technique, is an integrated circuit feature which prevents electric current leakage between adjacent semiconductor device components.
The BEOL process deposits metalization layers on the silicion to interconnect the individual devices generated during FEOL (bottom). CMOS fabrication process. Back end of the line or back end of line (BEOL) is a process in semiconductor device fabrication that consists of depositing metal interconnect layers onto a wafer already patterned with devices.
Simplified process of fabrication of a CMOS inverter: Image title: Simplified process of fabrication of a CMOS inverter on p-type substrate in semiconductor microfabrication, drawn by CMG Lee. Note: Gate, source and drain contacts are not normally in the same plane in real devices, and the diagram is not to scale.
TSMC began risk production of 256 Mbit SRAM memory chips using a 7 nm process in April 2017. [125] Samsung and TSMC began mass production of 7 nm devices in 2018. [126] Apple A12 and Huawei Kirin 980 mobile processors, both released in 2018, use 7 nm chips manufactured by TSMC. [127]
Wafer fabrication is a procedure composed of many repeated sequential processes to produce complete electrical or photonic circuits on semiconductor wafers in a semiconductor device fabrication process. Examples include production of radio frequency amplifiers, LEDs, optical computer components, and microprocessors for computers. Wafer ...
