ABSTRACT
Businessmodels for integrated circuit (IC) andmicroelectromechan-
ical systems (MEMS) manufacture can be divided into in-house and
foundry operations. Companies operating the in-house model have
both design and manufacturing capabilities and produce their own
products (e.g., Intel, Samsung, STMicroelectronics, Bosch). A foundry
offers a manufacturing service to other companies, using state-of-
the-art technology nodes in the case of IC foundries and a variety
of different technologies in the case of MEMS foundries (e.g., bulk
or surface microengineering). Foundries offering a manufacturing
service only are known as ‘pure play’. Companies without their own
manufacturing capability are known as ‘fabless’.
