Signetics

Signetics was an American semiconductor manufacturer established in Silicon Valley in 1961 by engineers who had previously worked at Fairchild Semiconductor. The founders believed that integrated circuits, rather than discrete transistors, would become the foundation of electronic equipment. They created the company specifically to design and manufacture integrated circuits, at a time when Fairchild was still cautious about pursuing ICs aggressively. The name Signetics was derived from the idea of signal-network electronics. The company initially pursued custom integrated circuits for individual customers and developed early diode-transistor logic products. Its first standard DTL circuits were announced in 1962. Signetics also introduced customization schemes that allowed customers to specify metallization or submit designs based on approved discrete components. The business model required substantial engineering and customer support, but early sales were insufficient to sustain the company. After its initial financing was nearly exhausted, Corning Glass Works invested $1.7 million in 1962 and acquired a controlling interest. The new capital supported manufacturing expansion and a more substantial marketing effort. A major turning point came in 1963, when the United States Department of Defense began encouraging the adoption of microelectronics because integrated circuits were smaller, more reliable, and less power-hungry than many discrete-component alternatives. Military contractors consequently increased their interest in custom ICs, an area in which Signetics was one of the few established suppliers. Sales expanded sharply in late 1963 and 1964, and Signetics became profitable. It enlarged its engineering organization and opened a major fabrication facility in Sunnyvale, at the time one of the largest IC manufacturing sites in Silicon Valley. Later production expanded to facilities in Utah, New Mexico, and other locations. Signetics briefly held an important position in the emerging IC market, but it faced aggressive competition from Fairchild. Fairchild reproduced or closely competed with Signetics circuits while using greater financial resources, manufacturing scale, and marketing strength to reduce prices. Signetics lost market share and returned to financial difficulty. Corning responded by removing much of the original management group and taking more direct control. Although Signetics recovered and continued to produce important devices, it did not regain its early market leadership. The company remained technologically influential. Around 1971 it introduced the 555 timer, marketed as the IC Time Machine. The inexpensive device became one of the most widely used analog ICs, supporting timing, oscillation, pulse-generation, and control applications. Signetics also developed or manufactured notable phase-locked-loop components, microprocessors, character generators, operational amplifiers, operational transconductance amplifiers, and field-programmable logic devices. Its application notes helped engineers and students understand practical IC design and contributed to the adoption of its products as de facto industry standards. Signetics became a public company in 1973, raising approximately $20.6 million through the sale of common shares. In 1975 it began second-source production for two Intel 3000-series bit-slice microprocessors and was acquired by Philips the same year. Philips continued using the Signetics name for a period, but the original American corporation was ultimately absorbed into Philips Semiconductors, which later became part of NXP Semiconductors. Signetics manufacturing in the United States reached its approximate peak around 1980. The Provo, Utah facility closed in 1992, with production redistributed to other sites. A separate South Korean assembly and test operation that had originated under Signetics was spun off by Philips in 1995 and continued independently under the Signetics name. Since…

Signetics was announced on October 16, 1961, at a facility on West Maude Avenue in Sunnyvale, California. Its founders came from Fairchild Semiconductor and departed because they believed integrated circuits represented the future of electronics, whereas Fairchild was then concentrating more heavily on discrete components. Signetics was organized to make ICs commercially and initially linked engineering closely with marketing rather than maintaining a separate research laboratory. Its name referred to signal-network electronics. The company announced early standard DTL circuits in 1962 and also offered customized IC approaches in which customers could define interconnection layers or provide approved full-custom designs. This approach was technically ambitious but commercially difficult. Signetics soon required additional capital, and Corning Glass Works invested $1.7 million in November 1962 for a 51 percent interest. Funding supported sales, marketing, and manufacturing growth. Government and military demand helped transform the company. During 1963 the U.S. Department of Defense encouraged microelectronics because ICs offered advantages in size, reliability, and power consumption. Military contractors explored custom circuits, giving Signetics a market opportunity. Sales accelerated in late 1963 and through 1964, profitability returned, and the company expanded its engineering staff and fabrication capacity. A large Sunnyvale fab made Signetics a major Silicon Valley IC manufacturer. Additional operations were later established in Orem and Provo, Utah, Albuquerque, New Mexico, and overseas. Signetics' early lead was challenged by Fairchild, which entered the IC market with substantial financial and manufacturing advantages and competed aggressively on price. Signetics lost market share and suffered renewed losses. Corning concluded that management performance was inadequate, removed much of the original leadership, and assumed tighter control. Signetics subsequently stabilized but remained more of an important innovator than the industry's market leader. Its product work covered both analog and digital electronics. The 555 timer, introduced around 1971, became the company's signature device and one of the most enduring IC designs in electronics. Other notable products included the NE565 phase-locked-loop device, the NE566 voltage-controlled oscillator, the 2650 eight-bit microprocessor, the 8X300 bipolar processor, the 2513 character generator, the 82S100 field-programmable logic array, and the NE5532 and NE5517 analog devices. Signetics application notes were widely used as practical educational material. Signetics sold shares to the public in 1973, raising about $20.6 million. It began second-source production for two Intel 3000-series bit-slice processors in 1975 and was acquired by Philips that year. The original company was eventually absorbed into Philips Semiconductors and later NXP. Signetics' U.S. manufacturing activity reached its approximate peak around 1980; its Provo operation closed in 1992. Philips spun off the Korean assembly and test business in 1995. That independent company continued using the Signetics name, but it is distinct from the historical American corporation described in the Signetics article.
