TSMC Optimizes Tank Truck Filling Process, Reducing Driver Duty Time by 50% and Improving Transportation Safety
To fulfill the promise laid out in the "White Paper on Supplier Transportation Management", TSMC has proactively established a supplier transportation safety culture and continues to promote a friendly workplace. Through its “On-site Contractor Personnel Support Program” the Company has optimized both the wafer transportation process and the tank truck filling process, which not only shortens driver work time by 50%, but also reduces the risks caused by fatigued driving. As of December 2021, more than 60,000 people have benefited from this program, ensuring driver health as well as public transportation safety.
Contractors are important partners in achieving quality excellence at TSMC. Through continuous improvement of our quality control system and a safe contractor working environment, we create a win-win partnerships and ensure a safe and undisrupted supply of raw materials.
Intelligent Filling Process to Enhance Tank Truck Transportation Efficiency and Driver Safety
The chemicals required by TSMC to manufacture wafers are transported by tank trucks to various fabs each day. As the truck filling process includes several procedures, TSMC’s Quality and Reliability Organization and its Material Supply Chain Management Division have collaborated to conduct field inspections and interviews on daily operation since 2018 in an attempt to optimize drivers’ work conditions and procedures. Based on the results, TSMC implemented five major improvements in transportation efficiency, successfully shortening the filling process time by 50% and alleviating long waiting times for drivers. These improvements have been implemented in all 12-inch fabs in Taiwan and will be the standard for new fabs.
TSMC’s Five Major Improvements on Tank Truck Transportation Efficiency

Adhering to the concept of a mutually beneficial partnership with contractors, TSMC will continue to improve the availability of equipment in its fabs. The operation will be monitored by a dedicated team that will prevent filling operation delays due to equipment abnormalities, providing contractors with a better work environment.
