IBM Driven Intel Driven Consortia Driven (I300I/J300/etc) Consortia Driven (??I450I/J450??) Alan Allan IRC Slide FI TWG Wafer Generation Timing Proposal: Make 450mm Wafer Intercept at 2013 • Background • Wafer size changes are driven by productivity curve to continue Moore’s law. Need to move to 450mm may be accelerate or slow based on economic needs. • Historically, wafer size changes are done every 9 years • Logic for 2013 • 1999 roadmap placed 450mm change at 2014. Data to predict the intercept is no better now so use the same approximate timing -> use 2013 node since 2014 node does not exist.

Ref.+ 6 yrs F’cast (ex. 2001 through 2007), annually - Long-Term Years : Following 9 years (ex.: 2010, 2013, and 2016), every 3 years • Technology Node : - General indices of technology development. - Approximately 70% of the preceding node, 50% of 2 preceding nodes. - Each step represents the creation of significant technology progress - Example: DRAM half pitches: 130, 90, 65, 45, 32, 22, 16 nm -Smallest 1/2 pitch among DRAM, ASIC, MPU, etc • Year of Production: - The volume = 10K units (devices)/month. ASICs manufactured by same process technology are granted as same devices - Beginning of manufacturing by a company and another company starts production within 3 months • Technology Requirements Color: - : Manufacturable Solutions are NOT known - : Manufacturable Solutions are known - : Manufacturable Solutions exist, and they are being optimized - Red cannot exist in the next three years (2002, 2003, 2004) ** - Yellow cannot exist the next year (2002) ** White Red Yellow ** Exception [By Review/Approval of IRC]: Solution NOT known, but does not prevent Production manufacturing
