Semiconductor Manufacturing Technology by Michael Quirk and Julian Serda. an assembly technology, National Semiconductor utilizes a rigorous system to characterize and verify the suitability of the change for high-volume production. The wafer is fabricated, tested, sawed/separated, packaged, and tested again. Semiconductor device fabrication is the process used to manufacture semiconductor devices, typically the metal–oxide–semiconductor (MOS) devices used in the integrated circuit (IC) chips that are present in everyday electrical and electronic devices. Give an overview of the six major process areas and the sort/test area in the wafer fab. A semiconductor manufacturing process differs markedly from other processes. Similar to semiconductor integrated circuit manufacturing, MEMS devices are manufactured on a silicon or glass “wafer”. Search for more papers by this author. The semiconductor manufacturing process flow, when highly simplified, can be divided into two primary cycles of transistor and interconnect fabrication.
