TSMC misses sustainability goals as it ramps up chip output

Adoption of more advanced tools drives up water and energy use

TAIPEI -- Taiwan Semiconductor Manufacturing Co. failed to hit its sustainability targets for water usage and waste generation last year as the world's biggest semiconductor company ramped up output of the industry's most advanced chips.

According to TSMC's latest corporate sustainability report, the company's use of water, electricity and raw materials increased for the third straight year in 2020, due mainly to the building of new factories but also to the introduction of more advanced chip manufacturing technologies -- namely the so-called 5-nanometer chip production technology used in making iPhone and Mac processors.
