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]

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.
A process design kit (PDK) is a set of files used within the semiconductor industry to model a fabrication process for the design tools used to design an integrated circuit. The PDK is created by the foundry defining a certain technology variation for their processes. It is then passed to their customers to use in the design process.
Device technology: integrated circuit fabrication process, oxidation, diffusion, ion implantation, photolithography, n-tub, p-tub and twin-tub CMOS process. [12] [13] Analog circuits: Equivalent circuits (large and small-signal) of diodes, BJT, JFETs, and MOSFETs. Simple diode circuits, clipping, clamping, rectifier.
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.
Key to the advance was the discovery that heavily doped poly-silicon was conductive enough to replace aluminum. This meant the gate layer could be created at any stage in the multi-step fabrication process. [1]: p.1 (see Fig. 1.1) In the self-aligned process, the key gate-insulating layer is formed near the beginning of the process.
Among the many solutions proposed for the computer simulation, one of the most promising methods is an Initial Transient Analysis (ITA) proposed by Rodriguez-Villegas, [18] where the FGs are set to zero volts or a previously known voltage based on the measurement of the charge trapped in the FG after the fabrication process. A transient ...
