Spaceflight and military applications traditionally used hermetically packaged microcircuits (HPMs). CML Microcircuits (UK) Ltd is a British-based manufacturer of semiconductors. These cortical microcircuits are grouped into cortical columns and minicolumns. However, most modern integrated circuits are only available as plastic encapsulated microcircuits (PEMs). CML Microcircuits is believed to be the oldest fabless semiconductor company in the UK. Finally, the individual microcircuits are separated by wafer dicing and packaged as an integrated circuit. In 1963, Stewart-Warner established an integrated circuit fabrication facility, Stewart-Warner Microcircuits, in Sunnyvale, California. NEAR is the first APL spacecraft to use significant numbers of plastic encapsulated microcircuits (PEMs). His book with Kevin Morgan, "Microcircuits of Capital" (1988), was a result. Even more complex networks, macrocircuits, consist of multiple embedded microcircuits. In 1991, Gazelle Microcircuits, Gigabit Logic, and TriQuint all merged under the TriQuint name.
