The original title: The Second Quarter Global Wafer share: TSMC accounted for more than half, SMIC fifth this year, Wafer, lithography and other advanced semiconductor topics from time to time heated debate. The latest statistics from the Japanese media show that in the second quarter of this year, the number of global wafer fabs was 51.5% , with TSMC holding the No. 1 contract factory. Samsung was second with 18.8% . 3 ~ 5 are grid core, UMC and SMIC respectively. We can see that the gap between SMIC and TSMC is still relatively obvious, for the nominal process level of the gap, at the moment, but also frankly accept. TSMC and Samsung are the only two companies to have mass produced 7nm and are producing 5nm, with apple's A14 bionic processor being built at TSMC's Tainan Plant, which opened in 2018, it is expected to be the world's first mass produced 5nm mobile phone processor, with up to 15bn transistors integrated inside, 76% more than A13's 8.5 bn. If nothing else, TSMC's 3nm launch in 2022 could be the FINFET's curtain call. It is reported that 7nm per square millimeter can hold 96.5 million transistors, 5nm expansion to 170 million, 300 million 3nm will reach the scale. Oh, Shit
