Referred to respectively as the wafer fab equipment [2] or wafer front end [3] (equipment) market, both using the acronym WFE, the market is that of the manufacturers of the machines which in turn manufacture semiconductors.
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.
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 ...
multi-chip module (MCM) – an electronic assembly integrating multiple ICs, dies, chiplets, etc. onto a unifying substrate so that they can be treated as one IC; nanofabrication – design and manufacture of devices with dimensions measured in nanometers; node – see technology node; optical mask – see photomask
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 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 ...
Data about the cost of production, including machine time, labor time and materials used, as well as final production numbers, is provided from the MRPII system to accounting and finance. [ 5 ] For the companies that want to integrate their other departments with their manufacturing management, ERP software are necessary.
