-based Microchip Technology was acquiring the company for over US$10 billion, pending regulatory approval. In May 2018, it was announced that Microchip had completed its acquisition of Microsemi. In August 2018, Microchip discovered that Microsemi shipped large orders to distributors on discount before the closing of the acquisition and had a culture of excessive extravagance, casting some doubt on the future prospect of the acquisition.

History

1959 to 1970: Early years

Microsemi was founded in February 1959 in

Culver City, California Culver City is a city in Los Angeles County, California, United States. As of the 2020 census, the population was 40,779. Founded in 1917 as a "whites only" sundown town, it is now an ethnically diverse city with what was called the "third-most ...

session on "Components for Miniaturized Electronic Assemblies".
According to the Missiles and Rockets magazine, in 1964 "Molecular packaging of integrated circuits has been suggested by Microsemiconductor Corp. This would involve the same process the company uses for diodes it supplies to the Improved Minuteman program." Microsemiconductor is cited in 1965 as supplier of miniature silicon diodes that are "ideal to use as beam profile detectors or to measure depth-dose distribution of small collimated beams." by University of California's Ernest O. Lawrence Radiation Laboratory. In 1966, two of the company's engineers, E.S. Resnond and M.W. Stillwell, published a Production Engineering Measures Study, on High Voltage Oscillators. As of 1969, Microsemiconductor's address was still 11250 Plaza Court, Culver City, CA 90230.
On August 13, 1969, Standard Resources Corporation, from

, a close-end management investment company, filed at the U.S. Securities and Exchange Commission a request to merge with Microsemiconductor. This request disclosed that the major shareholders of Microsemiconductor as of May 31, 1969, were Arthur Feldon (31%), Steve Manning (31%) and Thomas C. Hall (10%). At the end of the proposed merger the company would retain the name Microsemiconductor. At the time, J.M. Kaplan's JemKap Inc owned 37.7% of the outstanding common shares of Standard, which would make him the owner of 18.9% of the surviving company. Standard Resources and Microsemiconductor merged in November 1969.

1971 to 2000: The Philip Frey Jr years

According to the ''Orange County Business Journal'', "In 1971, the New York operation was spun off and Philip Frey Jr. was brought on from Teledyne Inc.'s semiconductor division in Hawthorne to head Microsemiconductor. At the time, the company had annual sales of about $500,000, almost entirely to defense industry customers. In 1972, the company moved from Culver City to

. Microsemi still was almost exclusively a defense business in 1987, but by then sales were close to $50 million. That same year, the company did a $35 million convertible bond offering, the proceeds of which were used to acquire about a dozen companies, most of them struggling "bargain" buys. When the acquisitions began straining profitability, Frey didn't waste a lot of time admitting his mistake. In 1989, Microsemi began selling them off. Sales, which hit a then-high of $104 million in 1989, fell to $83 million by 1991. But they've grown almost every year since and are expected by analysts to exceed $150 million for the fiscal year just ended. (1996)" On July 1, 1982, Jemkap Inc acquired 48.6% of Microsemiconductor Class A Stock., and Microsemisemiconductor acquired the Siemens Components Group in

. Microsemiconductor renamed itself to Microsemi, in February 1983. On March 9, 1986, Microsemi, at the time a supplier of "high-performance semiconductor diodes in a variety of military, industrial and commercial products", issued 2.5 million shares of common stock. Up until this time, Jacob M Kaplan of New York owned or controlled 38.4% of the company shares, and was 94 years-old. Microsemi raised $26 million in the stock sale. Jacob Merril Kaplan, who was a philanthropist, died in Manhattan, NY on July 20, 1987. Microsemi was originally traded Over the Counter, commonly traded as MicrSm. On March 1, 1990, Microsemi joined the

exchange. On March 1, 1987, Microsemi sold $35M in convertible debentures. Between 1986 and 1990 Microsemi acquired over 60% of the shares of 11 companies. In June 1991 Microsemi created two join-ventures in Taiwan for packaging in Taiwan its component dies made in Santa Ana, California. Microsemi established its presence in Ireland in 1992 through the acquisition of a facility in Ennis Co. Clare. The Ennis facility's key competencies are the development, manufacturing and high reliability testing of semiconductors to meet stringent aerospace, satellite, medical and security standards. In July 1992 Microsemi acquired Unitrode's semiconductor products division. In February 1993 Microsemi's stock crashed 54%, because of a cash crunch. "Microsemi has been restructuring for several years as defense budget cuts have slowed its sales. In 1989, the company said it planned to sell or close 10 subsidiaries not related to its core business of manufacturing computer chips for use in electronics equipment ranging from military weapons to heart pacemakers. The company sold four subsidiaries, shut down one, combined two and retained three. The company took $20.5 million in write-offs during the past three years in connection with the restructuring." In April 1994 Microsemi formed a joint venture in China with Shanghai Electrical Apparatus, with 60% of the joint-venture belonging to Microsemi. Linfinity, whose CEO was Jim Peterson, was the first

2000 to 2018: The James J. Peterson years

On November 30, 2000, Microsemi promoted Jim Peterson to president and CEO. Jim Peterson was previously the president of Linfinity. In 2001 Microsemi relocated its headquarters from

. Between 2006 and 2011 Microsemi acquired a mix of space/hi-reliability focused companies (MDT, TSI, Babcock, Spectrum Microwave), defense/security focused companies (Endwave, White Electronics, Arxan, Brijot, AML), and also companies focused in discrete and IC power products for commercial applications (Advanced Power Technology, PowerDsine, Nexsem), as well as communications focused companies (PowerDsine, VT Silicon, Zarlink) a programmable logic company (Actel) and an ASIC design house focused on analog mixed-signal (ASIC Advantage). In 2011 Microsemi relocated its headquarters from

to Aliso Viejo, California. In August 2012, Microsemi marked its 20 years of operations in Ireland by naming Ennis its European headquarters. It also announced the inaugural Microsemi Scholarship in engineering at the

. In addition, the company funded a high-profile science and aerospace engineering programme in St. Flannan's school in Ennis. Microsemi works closely with the Industrial Development Authority (IDA Ireland), which is responsible for attracting and developing overseas investment in Ireland. Support from IDA Ireland was a key factor in the company's decision to invest in the region. Between 2012 and 2013 Microsemi acquired Timing companies (the timing business of Maxim Integrated Products, Symmetricom) in addition to Zarlink. In November 2013, Jim Peterson promoted Paul Pickle to COO and president, retaining the CEO position, and accumulating the position of chairman of the board. In 2014 Microsemi established a design group in Cork, Ireland, through the acquisition of Mingoa, which is focused on advanced system-on-chip (SoC) software and solutions with an emphasis on ARM processor-centric designs. Between 2014 and 2015 Microsemi acquired communications and data-center focused companies (Mingoa, Centellax, Vitesse, PMC-Sierra). In March 2016 Microsemi announced the divestiture of the defense-focused business units acquired between 2009 and 2011. In April 2016 Microsemi announced the divestiture of its Broadband Wireless Division, which was previously part of PMC-Sierra for $21 million. In October 2017 Microsemi announced the acquisition of the timing business of Vectron International from Knowles for $130 million. In March 2018, Microsemi's PolarFire FPGA was named "2017 Product of the Year" by Electronic Products China and 21ic.com. In March 2018 Microchip Technology announced it would acquire Microsemi for approximately $10 billion.
