Most of the leading fabless semiconductor companies such as AMD, Apple, ARM, Broadcom, Marvell, MediaTek, and Nvidia, are customers of TSMC, as are emerging companies such as Allwinner Technology, HiSilicon, Spectra7, and Spreadtrum.[15] Leading programmable logic device companies Xilinx and previously Altera also make or made use of TSMC's foundry services.[16] Some integrated device manufacturers that have their own fabrication facilities, such as Intel, NXP, STMicroelectronics and Texas Instruments, outsource some of their production to TSMC.[17][18] At least one semiconductor company, LSI, re-sells TSMC wafers through its ASIC design services and design IP portfolio.[dubious – discuss]
