Integrated device manufacturer
An integrated device manufacturer is a semiconductor company which designs, manufactures, and sells integrated circuit products.
IDM is often used to refer to a company which handles semiconductor manufacturing in-house, compared to a fabless [semiconductor company], which outsources production to a third-party semiconductor [fabrication plant].
Examples of IDMs are Intel, Samsung, Texas Instruments, Infineon and STMicroelectronics. Fabless companies include AMD, Nvidia, Qualcomm, and Zhaoxin, and examples of pure play foundries are GlobalFoundries, TSMC, and United [Microelectronics Corporation|UMC].
Due to the dynamic nature of the semiconductor industry, the term IDM has become less accurate than when it was coined.
OSATs
The term OSATs means "outsourced semiconductor assembly and test providers". OSATs have dominated IC packaging and testing.Fabless operations
The terms fabless, 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 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
