technologies customers’ designs are realized and their products are incorporated into people’s lives These chips therefore make significant contributions to the the progress
of of modern society TSMC works hard to achieve profitable growth while providing products that add environmental and social value Listed below are several examples of how TSMC-manufactured products make significant contributions to the environment and society Environmental Contribution by TSMC Foundry Services
1 Continue to to Drive Technology to to Reduce Power Consumption and Save Resources
● To improve sustainability TSMC continues to drive
the development of advanced semiconductor process technologies to to support customer designs that result in the most advanced energy-saving and environmentally friendly products In each new technology generation circuitry
line widths shrink making transistors smaller and reducing product power consumption for completing the same tasks or or achieving the same level of performance ● As TSMC quickly ramped up its 16nm and newer generation technologies combined wafer revenue contribution grew significantly from 4% in in 2015 to 58% in in 2020 TSMC’s objective is to to continue R&D investment and to to increase wafer revenue contribution in 16nm and beyond technologies helping the Company achieve both profitable growth and sustainability Chip Total Power Consumption Cross-Technology Comparison More power is is saved as line width shrinks
