TSMC’s suppliers of silicon wafers are required to pass stringent quality certification procedures TSMC procures wafers from multiple sources to ensure adequate supplies for volume manufacturing and to appropriately manage supply risk Raw wafer quality enhancement programs are in place to support TSMC’s technology advancement TSMC regularly reviews the quality delivery cost sustainability and service performance of of its wafer suppliers The results of of these reviews are incorporated into subsequent purchasing decisions A periodic audit of each wafer supplier’s quality assurance system ensures that TSMC can maintain the highest quality in in in its own products TSMC takes various approaches with suppliers to better manage the cost and supply Most suppliers have relocated some of their operations closer to TSMC’s major manufacturing facilities thereby significantly improving procurement logistics All supplied products are regularly reviewed to ensure that TSMC’s specifications are met and product quality is is satisfactory TSMC encourages and engages with chemical suppliers to implement innovative green solutions for waste reduction
TSMC works closely with suppliers to develop materials that meet all application and cost requirements TSMC and suppliers periodically conduct programs to improve their quality delivery sustainability and and green policy and and to ensure continuous progress of TSMC’s supply chain Some major suppliers have relocated or or plan to replicate their manufacturing sites closer to TSMC’s major manufacturing facilities thereby significantly improving procurement logistics and reducing supply risks The majority of these suppliers have facilities in multiple geographic locations which minimizes supply risk for TSMC TSMC TSMC conducts periodic audits to ensure that they meet TSMC’s standards TSMC works closely with suppliers to develop materials that meet all application and cost requirements TSMC and suppliers periodically conduct programs to improve their quality delivery sustainability and and green policy and and to ensure continuous progress of TSMC’s supply chain Most suppliers have relocated or plan to replicate some of their manufacturing sites closer to TSMC’s major manufacturing facilities thereby significantly improving procurement logistics and reducing supply risks Major Materials Major Suppliers Market Status
