In logic IC, Intel has been the leader since the invention of the 4-bit 4004 microprocessor as the central processing unit (CPU) in 1971 [ 38 ] and dominated the IDM. In the past two decades, the fabless (e.g., Qualcomm, Broadcom, Advanced Micro Device (AMD), NVIDIA, and MediaTek) and foundry (e.g., TSMC, GlobalFoundries (GF), United Microelectronic Corp (UMC), Semiconductor Manufacturing International Corp (SMIC), and Powerchip Semiconductor Manufacturing Corp (PSMC)) together are gaining market share [ 6, 39 ]. The market share of the top 10 foundries [ 40 ] is listed in Table. TSMC has the largest share (58.5%) of the foundry market. Altogether, Taiwan has 66.9% of the global foundry business. The top 10 customers of TSMC, as listed in Table, are dominated by US companies, including the device maker (Apple), fabless design companies, and even IDM (Intel).
