The planar process is a manufacturing process used in the semiconductor industry to build individual components of a transistor, and in turn, connect those transistors together. It is the primary process by which silicon integrated circuit chips are built, and it is the most commonly used method of producing junctions during the manufacture of ...
The planar process was invented by Jean Hoerni, with his first patent filed in May 1959, while working at Fairchild Semiconductor. [8] [9] The planar process was critical in the invention of Silicon Integrated circuit by Robert Noyce. [10]
LDMOS (laterally-diffused metal-oxide semiconductor) [1] is a planar double-diffused MOSFET (metal–oxide–semiconductor field-effect transistor) used in amplifiers, including microwave power amplifiers, RF power amplifiers and audio power amplifiers. These transistors are often fabricated on p/p + silicon epitaxial layers.
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.
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.
All model coefficients and material parameters are contained in a database library which can be modified or added to by the user. Even the equations to be solved can be specified by the end user.PROPHET was originally developed for semiconductor process simulation. Device simulation capabilities also exist now.

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]
