The steps involving testing and packaging of dies, followed by final testing of finished, packaged chips, are called the back end, [193] post-fab, [194] ATMP (Assembly, Test, Marking, and Packaging) [195] or ATP (Assembly, Test and Packaging) of semiconductor manufacturing, and may be carried out by OSAT (OutSourced Assembly and Test) companies ...
In the microelectronics industry, a semiconductor fabrication plant, also called a fab or a foundry, is a factory where integrated circuits (ICs) are manufactured. [1]The cleanroom is where all fabrication takes place and contains the machinery for integrated circuit production such as steppers and/or scanners for photolithography, etching, cleaning, and doping.
Front-End Engineering focuses on technical requirements and identifying main costs for a proposed project. [2] It is used to establish a price for the execution phase of the project and evaluate potential risks. It is typically followed by Detailed Design (or Detailed Engineering). The amount of time invested in Front-End Engineering is higher ...
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] FEOL generally covers everything up to (but not including) the deposition of metal interconnect layers.
In a radio receiver circuit, the RF front end, short for radio frequency front end, is a generic term for all the circuitry between a receiver's antenna input up to and including the mixer stage. [1] It consists of all the components in the receiver that process the signal at the original incoming radio frequency (RF), before it is converted to ...
front end of line (FEoL) – initial wafer processing steps up to (but not including) metal interconnect (see also back end of line, far back end of line, post-fab) heterogeneous integration – combining different types of integrated circuitry into a single device; differences may be in fabrication process, technology node, substrate, or function

Its combination of low raw material cost, relatively simple processing, and a useful temperature range makes it currently the best compromise among the various competing materials. Silicon used in semiconductor device manufacturing is currently fabricated into boules that are large enough in diameter to allow the production of 300 mm (12 in ...
