David A. Bloss is vice president in the Technology and Manufacturing Group and the director of fab equipment supply chain at Intel Corporation. He oversees Intel’s worldwide capital equipment business for wafer manufacturing facilities, which includes responsibility for fabrication, lithography and metrology equipment, equipment spares and service, and factory automation in support of technology development and high-volume manufacturing. Dave began his Intel career in 1994 as a factory automation software engineer developing and implementing automated material-handling systems for Intel’s 200mm wafer fabrication facilities. He subsequently held various development, support and leadership positions within Intel’s factory automation organizations throughout the company’s transition to 300mm wafer manufacturing, including director of technology manufacturing engineering automation with responsibility for the factory automation supply chain. He has also held a variety of leadership positions in global supply management, including director of Intel Resale Corporation, where he was responsible for the sale of excess product inventory, factory equipment and other assets. Intel recognized Bloss with an Intel Achievement Award in 2000 for his contribution to Intel’s transition to 300mm wafer manufacturing through standardized equipment and automated material-handling systems. This work also led Bloss to write extensively on topics related to 300mm automated manufacturing and control in semiconductor factories, including approximately 20 technical papers, presentations and specifications for various industry associations such as Semiconductor Equipment and Materials International (SEMI) and the semiconductor industry’s I300I consortium. Dave received his bachelor’s degree in computer and electrical engineering from Purdue University.
