Foreword
The reason to have this post
Investors who want to seriously study TSMC must want to know how many wafer fabrication foundry (aka fabs) and assembly and testing house TSMC currently and in the future have? The information of this article is that I have spent some time until today, based on TSMC’s annual report, company website, and news reports in both Chinese and English media.

My main sources of information are:
- TSMC web site.
- TSMC financial report.
- Public information published by TSMC.
- Information published by media around the world.

TSMC discussion in my books
I have discussed the company Nvidia (ticker:NVDA) in two recent books; including:
In my book “The Rules of Super Growth Stocks Investing“:
- Sections 2-4, the entire section is dedicated to introducing the company TSMC
- Section 3-3, analyze the business development of technology companies to grasp the pulse of key industries
In my book “The Rules of 10 Baggers“:
- Section 3-2, the entire section is dedicated to introducing TSMC and the global semiconductor supply chain.
Capacity expansion
In 2022, TSMC announced in a public technical conference:
- The rate of factories construction has increased from 2 per year in 2017 to 2019 to 6 per year in 2020 to 2022.
- Focus on the production capacity of 7, 5 and 3 nanometers in advanced processes, and increase at a compound growth rate of 70% from 2018 to 2022. The 5nm capacity will be four times what it was two years ago.
- Expand the special process production capacity, and the 12-inch special process production capacity will increase by 14% from 2021 to 2022.
