UI Factory Integration Scope and Drivers Factory Operations Production Equipment Factory Information & Control Systems AMHS Facilities Si Substrate Mfg Chip Mfg Wafer Mfg Product Mfg Distribution Reticle Mfg • FEOL • BEOL • Probe/Test • Singulation • Packaging • Test Increasing cost & Cycle time implications • Factory is driven by Cost, Quality, Productivity, and Speed • Reduce factory capital and operating costs per function • Faster delivery of new and volume products to the end customer • Efficient/Effective volume/mix production, high reliability, & high equipment reuse • Enable rapid process technology shrinks and wafer size changes
Key Technologies that will Impact Factory Design • 2007 and future years were targeted to meet productivity and capture technology requirements • Key process & device technology intercepts that will impact the factory design are Extreme Ultraviolet Litho (EUVL), New Device Structures, new materials, wafer size conversion & huge productivity improvements • Economic and business challenges are equal to our manufacturing and process technology challenges in scope and breadth to attain efficiency and effectiveness Planning for 300’/450mm EUVL in Production? New Device Structures? Next Wafer Size in Production?
