Today, there are a few IDMs, such as Intel, who build almost all of their own chips in their own fabs; there are foundries, such as TSMC and GlobalFoundries, who build none of their own chips, they just build wafers for other companies; and then there are fabless semiconductor companies, such as Xilinx and Qualcomm along with their fab-lite cousins, like Texas Instruments, who do their own design, sell their own products, but use foundries for all or part of their manufacturing.
