Integrated device manufacturer

The term OSATs means "outsourced semiconductor assembly and test providers". OSATs have dominated IC packaging and testing. ==Fabless operations==

The terms fabless (fabrication-less), foundry, and IDM are now used to describe the role a company has in a business relationship. For example, Freescale owns and operates fabrication facilities (fab) where it manufactures many chip product lines, as a traditional IDM would. Yet it is known to contract with merchant foundries for other products, as would fabless companies. ==Manufacturers==

Many electronic manufacturing companies engage in business that would qualify them as an IDM: • Analog Devices (and previously Maxim Integrated Products) • ams AG • Changxin Memory Technologies • CR Microelectronics • Fujitsu • Good-Ark Electronics • Hitachi • IBM (was integrated, up to 2015, then fabless) • Infineon (and previously Cypress Semiconductor) • Intersil (now subsidiary of Renesas) • Intel • LSI Corporation (acquired, not part of fabless Broadcom) • Matsushita • MACOM • Microchip Technology • Micron Technology (and previously IM Flash Technologies) • Mitsubishi • National Semiconductor (became part of Texas Instruments) • Nexperia • NXP (formerly Philips + Freescale Semiconductors) • OMMIC (Acquired by MACOM) • ON Semiconductor • • Qorvo • Renesas (formerly NEC semiconductor) • Samsung • Shanghai Belling • SK Hynix • STMicroelectronics • Sony • Texas Instruments • Tsinghua Unigroup • Toshiba • Yangtze Memory Technologies == Reading ==
