Want to learn more about the major semiconductor equipment categories? The Semiconductor Equipment Market Briefs discuss the four major equipment categories which include, Wafer Processing Equipment, Other Front End Equipment, Test Equipment, and Assembly and Packaging Equipment. The briefs include category descriptions, technology trends, and historical market data from 1991 to last year.
|SEMI Equipment Brief: Wafer Fab Brief (PDF)|
Semiconductor fabrication consists of a series of processes in which a device structure is manufactured by applying a series of layers onto a substrate, most commonly on silicon. This involves the deposition and removal of various thin film layers. The areas of the thin film that are to be deposited or removed are controlled through photolithography. Each deposition and removal process is generally followed by cleaning as well as inspection steps.
|SEMI Equipment Brief: Test Equipment (PDF)|
There are various types of electrical and reliability tests conducted at different stages of assembly and for different purposes once the wafer fabrication process is finished. Tests include die sort test on wafers, electrical and environmental testing, and burn-in on packaged devices.
|SEMI Equipment Brief: Assembly and Packaging (PDF)|
There are two main purposes for assembling the bare semiconductor device into a package. First, the package provides mechanical and environmental protection to the bare die. Second, the package provides an electrical connection between the die and the printed circuit board (PCB). Nowadays, there are a tremendous number of package types, form factors, and process techniques used in assembly and packaging.

Other Front-End equipment is a “catch-all” phrase for equipment that is used in frontend manufacturing but not in wafer processing. It includes: Wafer Manufacturing equipment, Photomask/Reticle equipment and Fabrication Facility equipment.
