ISMI test wafer operations 450mm equipment installations continues Bare wafer particle/edge inspection Wafer cleaning Film thickness measurements EFEMs / wafer sorters FOUP wash 450mm test wafer processing experiments are progressing Wafer cleaning Metrology inspections ISMI continues working with suppliers on test wafer capabilities 10
ISMI prototype wafer cleans tool SSEC Wet clean tool installation complete in SEMATECH cleanroom SC1 / SC2 cleaning capability 12mm pitch loadport Cleaning experiments underway Cleaner wafers becoming available in ISMI wafer bank Particle experiments with loadports / carriers underway 11
450mm test wafer utilities matrix Collecting early 450mm utility projections Inputs will be used for 450mm test wafer facility planning Supplier surveys Consolidate surveys Supplier estimates for 450mm equipment facility requirements are requested 12
450mm demonstration test methodology 13
450 mm demonstration test methodology (450 DTM) The 450 DTM provides an efficient equipment demonstration model for the industry Consolidated inputs from IC makers and suppliers Clear and consistent procedures; standardized methodology for common equipment requirements Equipment demonstrations will focus on process repeatability, stability, and equipment reliability As demonstrations begin, engagement and input from IC maker and equipment suppliers is key 14
450mm factory integration 15
Reduced standards development time ISMI s ITB testing helped to enable a 60-65% time reduction in FI standards development vs. 300mm 300mm transition FI standards transition Org standards published Provisional or full standards published Decision to start wafer size transition and standards development Approved FI standards published 450mm transition Ongoing prototype testing 1995 1997 1999 2001 2007 2009 2011 16
ITB lab testing focused on the latest FOUPs, MACs and load ports FOUPs Carriers 12mm Pitch Std FOUPs MAC Carrier 12mm Pitch Std MACs TDK 12 mm pitch load port under continuous cycling Completed >123 k cycles with FOUPs Gudeng 12mm Pitch Latch Key FOUP Brooks 12mm pitch load port, compatible with FOUPs and MACs cycling at supplier site Completed >34 k cycles with FOUPs Planning MAC testing in Q3-2010 Sinfonia 12mm pitch load port cycling with latest FOUPs Completed >183 k cycles with FOUPs Working with Sinfonia to test new MAC/FOUP compatible Load port Entegris 12mm Pitch Latch Key FOUP 17
AMHS testing planned for H2 2010 450mm OHT 450mm Stocker New 450mm stockers and transport systems are under advanced development at suppliers sites ISMI will assess systems in H2 10 against ISMI 450mm guidelines and interoperability with 450mm standard carriers and load ports Goal is to demonstrate AMHS will be ready for 450mm pilot lines 18
Summary 450mm factory integration >5.0M robotic moves and >648k load port cycles completed in the ITB with prototype carriers Upgrades to prototype 12mm pitch Std FOUPs, load ports and EFEMs continued to demonstrate good interoperability and reliability Sun-setting ITB after completion of MAC, MAC load port (i.e., new standard load ports), and interoperability with FOUPs and MACs testing Working with AMHS Suppliers to complete evaluations of stockers and overhead hoist transport before end of 2010 19
