Etching is a critically important process module in fabrication, and every wafer undergoes many etching steps before it is complete. For many etch steps, part of the wafer is protected from the etchant by a "masking" material which resists etching. In some cases, the masking material is a photoresist which has been patterned using photolithography.
The dry etch is then performed so that structured etching is achieved. After the process, the remaining photoresist has to be removed. This is also done in a special plasma etcher, called an asher. [14] Dry etching allows a reproducible, uniform etching of all materials used in silicon and III-V semiconductor technology. By using inductively ...
Early semiconductor processes had arbitrary names for generations (viz., HMOS I/II/III/IV and CHMOS III/III-E/IV/V). Later each new generation process became known as a technology node [17] or process node, [18] [19] designated by the process' minimum feature size in nanometers (or historically micrometers) of the process's transistor gate ...
Indium and gallium are group III elements of the periodic table while arsenic is a group V element. Alloys made of these chemical groups are referred to as "III-V" compounds. InGaAs has properties intermediate between those of GaAs and InAs. InGaAs is a room-temperature semiconductor with applications in electronics and photonics.
etching (etch, etch processing) – chemically removing layers from the surface of a wafer during semiconductor device fabrication fab – a semiconductor fabrication plant fan-out wafer-level packaging – an extension of wafer-level packaging in which the wafer is diced, dies are positioned on a carrier wafer and molded, and then a ...

Deep reactive-ion etching (DRIE) is a special subclass of reactive-ion etching (RIE). It enables highly anisotropic etch process used to create deep penetration, steep-sided holes and trenches in wafers /substrates, typically with high aspect ratios .
A III-V compound semiconductor is an alloy that contains elements from group III and group V of the periodic table. [1 Pages in category "III-V semiconductors" ...
