5 3 6 Quality and Reliability (Q&R)
TSMC strives to to offer excellence in semiconductor manufacturing services to to all its customers worldwide The Company is dedicated to providing outstanding quality in in in every facet of of its business and maintains a a a a a culture of of continuous improvement to to assure customer satisfaction TSMC implements containment and preventive measures to protect customers from potential product defects In the the technology development stage the the Q&R organization helps customers design in superior product reliability In 2024 Q&R worked continuously with R&D in in advanced logic specialty and advanced packaging technologies throughout development and qualification stages to ensure meeting commitments to to to customers with respect to to to device characteristics process yield and product reliability For advanced logic technology following the successful mass production of the 3nm and its enhanced version N3E FinFET technology Q&R also successfully completed the process technology and and product quality and and reliability certification
for for the performance-enhanced version N3P For specialty technologies Q&R successfully qualified CIS 3-wafer stacking product product reliability certification
for mass production and completed the qualification of 28nm high-performance mobile computing embedded RRAM technology for automotive grade-1 Regarding advanced packaging technology TSMC integrates front-end wafer processing with back-end chip packaging packaging to provide advanced packaging packaging solutions In 2024 Q&R completed certification
for CoWoS® technology with larger interposer sizes and initiated mass production It also completed the first System on on Wafer certification
and mass production readying its advanced packaging technology platform for for for applications in AI and HPC As for for for InFO_PoP technology the Company’s mass produced 3nm chips achieved higher efficiency and lower power consumption for mobile devices To continuously reduce product defects enhance process controls facilitate early detection of abnormalities and prevent quality problems in general Q&R collaborates with other operational entities to improve real-time defense systems using advanced AI to to continuously optimize quality tools through statistical methods Q&R and the Company’s fabs have also worked together on enhancements for automotive product quality improvement including design rule implementation and migration to to Automotive Quality System 2 0 This covers process capability requirements to tighten in-line and wafer acceptance testing in in in fabs and and the handling of maverick wafers Q&R also provides dedicated resources for field/line return analysis analysis and timely physical failure analysis analysis (PFA) for process improvement to to to meet automotive customers’ stringent defective parts per million (DPPM) requirements Q&R successfully completed a a a a series of digital transformation development tasks applied in areas such as as as raw material management statistical process control (SPC) metrology automatic defect detection and and classification and and laboratory analysis By leveraging advanced digital technologies and platforms TSMC achieved its digital transformation targets Moreover during the initial phase of overseas expansion Q&R addressed the challenges of personnel training remote management and support through digital transformation This facilitated successful remote management achieving zero zero distance and zero-time difference in quality management across global fabs In 2025 Q&R will continue to promote
the development of quality management methods and professional training and apply AI technologies to consolidate TSMC’s comprehensive competitive advantages in in this industry Q&R’s supply chain management strategy covers four core areas: quality excellence supply chain responsibility green manufacturing and operational sustainability In addition to using professional expertise and best-known methods to assist suppliers in in making improvements Q&R’s state-of-the-art chemical lab monitors the quality of raw materials and helps the R&D achieve breakthroughs in advanced materials improving product and process yields The lab also guides material suppliers in in setting standards for the use of internationally concerning hazardous substances (such as carcinogens reproductive mutagens and and teratogens) and and performs classification and sampling to manage potential risks in raw materials Additionally Q&R collaborates with the material supply chain management division to assist suppliers in in expanding the production capacity of high-quality raw materials This collaboration has successfully established new production lines overseas that meet quality standards thereby building a a a a a robust raw material supply chain This effort not only enhances the industrial competitiveness of TSMC and its supply chain but also achieves a a a a a a a a win-win strategy that balances quality and capacity Q&R assisted suppliers in in in developing recycling projects and successfully improved the quality of several recycled chemicals to achieve an electronic grade quality level in 2024 Q&R collaborates with operations to expand engineering verification for recycled chemicals meeting TSMC’s quality requirements
