Hunting For Macro Defects


Detecting macro-defects early in the wafer processing flow is vital for yield and process improvement, and it is driving innovations in both inspection techniques and wafer test map analysis. At the wafer level, a macro-defect can affect more than one die, and in some cases large regions of a wafer. Finding macro defects can indicate a significant issue with a process module, a particular fi... » read more

Accelerating Digital Transformation With Tight Integration Of Manufacturing Data


Many semiconductor companies are involved in digital transformation of their overall processes and operations. Manufacturing is one of the most critical and value generating processes in a semiconductor company. Being able to tightly integrate manufacturing with the rest of the enterprise is a critical element of a successful digital transformation program. Recognizing the value of real-time... » read more

Cutting IC Manufacturing Costs By Combining Data


Experts at the Table: Semiconductor Engineering sat down to discuss the benefits of incorporating financial data into fab floor decision-making, including what kind of cost data is most useful, with Dieter Rathei, CEO of DR Yield; Jon Holt, senior director of product management at PDF Solutions, Alex Burlak, vice president of advanced analytics and test at proteanTecs; and Dirk de Vries, techni... » read more

Full-Chip Voltage Contrast Inference Using Deep Learning; You Only Look Once: Voltage Contrast (YOLO-VC)


Abstract: The electron beam inspection methodology for voltage contrast (VC) defects has been widely adopted in the early stages of sub-10nm logic and memory technology development, as well as in new product introductions. However, due to throughput limitations, full-chip inspection at the 300mm wafer scale remains impractical for yield ramp and production applications. To address this challeng... » read more

Chip Industry Week In Review


Worldwide silicon wafer shipments declined nearly 2.7% to 12,266 million square inches in 2024, with wafer revenue contracting 6.5% to $11.5 billion, according to the SEMI Silicon Manufacturers Group. CSIS released a new report, “Critical Minerals and the Future of the U.S. Economy,” with detailed analysis and policy recommendations for building a secure mineral supply chain for semicond... » read more

Transformational Opportunities Coming To Semiconductor Manufacturing


During the GSA US Executive Forum in September 2024, a panel discussion brought together Marco Chisari, EVP from Samsung Semiconductor, Jeff Howell, Global VP for High Tech at SAP, and John Kibarian, CEO of PDF Solutions. The purpose of the discussion was to compare and contrast the perspectives from one of the largest global semiconductor companies with that of the most widely used enterpri... » read more

Silent Data Errors Still Slipping Through The Cracks


Silent data corruption errors in large server farms have become a major concern of cloud users, hyperscalers, processor manufacturers and the test community. Silent data errors (also called silent data corruption errors) are hardware errors that occur when an incorrect computational result from a processor core goes undetected by the system. The data is silently corrupted because neither sof... » read more

IC Equipment Communication Standards Struggle As Data Volumes Grow


The tsunami of data produced during wafer fabrication cannot be effectively leveraged without standards. They determine how data is accessed from equipment, which users need data access and when, and how fast it can be delivered. On top of that, best practices in data governance and data quality are needed to effectively interpret collected data and transfer results. When fab automation and ... » read more
