Currently, almost all the top-end smartphones are packed with chips based on a 7nm process node. But we know TSMC’s 5nm chips will come in late 2019 or early 2020. This simply means, in a couple of years, the mobile industry will enter a new era, where everything will be done faster and more productive. But this is not the limit. In August, we learned the Taiwanese semiconductor company invested $19 billion to build a 3nm wafer fab. Today, according to the Taiwanese ‘Economic Daily’ report, TSMC’s 3-nanometer factory passed the environmental assessment. According to the original scheduling, the world’s first 3-nanometer plant is expected to start construction in 2020 and complete equipment installation in 2021. Moreover, it’s expected to be put into operation as early as the end of 2022 and early 2023.
