The 15th place in the US stock trading volume on Thursday, the wafer foundry taiwan semiconductor, rose by 5.34%, with a turnover of 2.778 billion US dollars. According to reports, taiwan semiconductor's 2nm process technology has started the risk trial production in July, earlier than expected. There had been reports in early July that taiwan semiconductor's 2nm process technology would start risk trial production in mid-July, one quarter earlier than the market's general expectation. In the latest report, some media have disclosed that the risk trial production of taiwan semiconductor's process technology began in July, which is basically consistent with previous reports. Analysts believe that taiwan semiconductor is accelerating to ensure stable yield before mass production. Media reports also point out that in December of last year, taiwan semiconductor had already shown the test results of their 2nm process technology prototype to some major customers including apple and nvidia. As a major customer of taiwan semiconductor for many years, apple is expected to be the main customer after the mass production of advanced process technology, as it has been with 7nm, 5nm, and 3nm process technology, and is expected to be the same with the 2nm process technology. Several media outlets have mentioned that apple has already reserved all initial production capacity of taiwan semiconductor's 2nm process technology.
