How Many Kilowatt-Hours Does It Take To Make a Single Chip?

It’s summer, and it’s that time of year when electricity is tight.

As the foundation of modern science and technology, the chip manufacturing industry also has big power consumption, especially after the introduction of the 7-nanometer chip manufacturing process into the EUV lithography machine.

Few people know how much power it takes to make a single chip, but here’s a look at the public data from the leading chipmaker, TSMC:

  • (1) general power consumption of chip manufacturing can be assessed by kWh/unit wafer area (cm^2), according to TSMC data, the average power consumption per wafer is now about 1 kWh/cm^2 (chip area), of course, different manufacturing processes will vary, generally speaking, a chip consumes one degree of electricity is very normal;
  • (2) another way to assess power consumption per wafer (equivalent to an 8-inch wafer) is a photomask power consumption, the average data is about 10 degrees/wafer (per photomask), for complete manufacturing of wafers, less than 20-30, more than 70-80 photomask, a wafer needs to consume an average of 600 degrees of electricity is also very normal;
  • (3) TSMC now produces more than 30 million 8-inch (equivalent) wafers a year, so it is normal to consume more than 20 billion kilowatts of electricity per year.

The problem is that currently, Taiwan Province is now short of electricity and water, so the future is only the motherland is a good place for chip manufacturing ……
