Fabless manufacturing is the design and sale of hardware devices and semiconductor chips while outsourcing the fabrication (or "fab") of the devices to a specialized manufacturer called a semiconductor foundry. Foundries are typically, but not exclusively, located in mainland China and Taiwan[1][2][3][4] because of the generally low cost of labor. Thus, fabless companies can benefit from lower capital costs while concentrating their research and development resources on the end market.

The credit for pioneering the fabless concept is given to Bernie Vonderschmitt of Xilinx and Gordon A. Campbell of Chips and Technologies. The first fabless semiconductor company, the Western Design Center, was founded in 1978. Xilinx, founded in 1984, was the first to "truly" separate the design of chips from their manufacture.[5]


Prior to the 1980s, the semiconductor industry was vertically integrated. Semiconductor companies owned and operated their own silicon-wafer fabrication facilities and developed their own process technology for manufacturing their chips. These companies also carried out the assembly and testing of their chips, the fabrication.

Meanwhile, with the help of private-equity funding, smaller companies began to form, with experienced engineers exercising their entrepreneurial prowess by establishing their own integrated circuits (IC) design companies focused on innovative chip solutions.[citation needed]

As with most technology-intensive industries, the silicon manufacturing process presents high barriers to entry into the market, especially for small start-up companies. At the same time, Integrated Device Manufacturers (IDMs) had excess production capacity. The smaller companies began relying on IDMs to manufacture the chips they were designing.

These conditions underlay the birth of the fabless business model. Companies were manufacturing ICs without owning a fabrication plant. Simultaneously, the foundry industry was established by Dr. Morris Chang with the founding of Taiwan Semiconductor Manufacturing Corporation (TSMC). Foundries became the cornerstone of the fabless model, providing a non-competitive manufacturing partner for fabless companies.

In 1994, Jodi Shelton, along with a half a dozen CEOs of fabless companies, established the Fabless Semiconductor Association (FSA) to promote the fabless business-model globally.

In December 2007, the FSA transitioned to the GSA, the Global Semiconductor Alliance.[6] The organizational transition reflected the role FSA had played as a global organization that collaborated with other organizations to co-host international events.

Industry growth and success[edit]

The fabless manufacturing model has been further validated by the conversion of major IDMs to a completely fabless model, including (for example) Conexant Systems, Semtech, and most recently, LSI Logic. Today most major IDMs including Apple Inc., Freescale, Infineon and Cypress Semiconductor have adopted the practice of outsourcing chip manufacturing as a significant manufacturing strategy. As of 2007, the fabless model is the preferred business model for the semiconductor industry[citation needed].
