The shortage of automotive chip supply that began at the end of last year has spread to the entire semiconductor industry, highlighting the importance of China's Taiwan region in foundry. Analysts believe that TSMC’s influence can no longer be compared with market share, and its advanced process technology is almost beyond the reach of manufacturers at this stage.

According to data from TrendForce, a market research agency, the revenue of wafer foundries in Taiwan will account for more than 60% of total global revenue in 2020, of which TSMC will account for 54%.

Juheng.com reported that Shanghai Gavekal Dragonomics (Gavekal Dragonomics) technology industry analyst Wang Dan said that although TSMC only focuses on foundry, it has become the first choice of many advanced semiconductor manufacturers.

Wang Dan pointed out that TSMC’s market accounted for 50%, but this does not fully reflect the company’s importance in the semiconductor industry, because TSMC currently has almost no rivals in advanced manufacturing processes.

Sources previously said that TSMC plans to invest more than $15 billion in 2021 to advance the company's 3nm process technology. TSMC Chairman Liu Deyin also revealed that not only did the development of the new process go smoothly, it was even faster than expected, and its 3nm process could be commercially available in 2022.

It is reported that compared with the 5nm process, the 3nm process can increase the transistor density by 70%, or increase the performance by 15%, and reduce the power consumption by 30%.
