5. What Is A Supply Chain in Semicon? • A supply chain is a network of facilities that performs the • functions of • procurement of material, • transformation of material to intermediate and finished goods, • and distribution of finished products to customers. Sub ASSY Sub F/T 60 ~ 70 days 9 - 14 days 15 - 20 days FAB I 1 - 2 days C/P F/T wafer bank die bank FAB 2 F/G Fabrication Probing Assembly Testing

6. FT Process FAB Process CP Process Supply Demand Supply Supply Supply Uncertainty Plagues the Supply Chain • The Real Challenge in A Supply Chain - Uncertainty* • Different Sources of Uncertainties Exist along A Supply Chain • Demand: forecasting mismatch, demand volume, product mix, unexpected changes • Process: yield, machine downtimes, WIP, process hold • Supply: quality, reliabilities of FAB wafer supply and back-end capacity supply ASSY Process *Tom Davis, “Effective Supply Chain Management”, Sloan Management Review, 1993.

14. Why Supply Chain Management?

15. Fact Planning Issues Faced Needs • Weak integration between planning and execution • Enterprise visibility of planning process and multi-user access enable better process and and convincing results • Lack of due date projection capability in foundry environment • Quickly generate ATP & CTP to customer • Limited visibility into capacity constraints • Concurrent planning & optimizations of all constraints. Problem windows and real-time simulation capabilities to react in a timely manner

16. Fact Current Manufacturing planning issues Needs • Islands of data, multiple excel spreadsheets consuming vast amounts of planner time • Single entry of forecasting information, company-wide visibility • Automatic tools with both planning and execution data inputs • Manual Work with limited dimensional view (e.g. Total volume by Product) • Lack of rapid re-plan capability • Reduce planning cycle time allows daily planning and rapid re-planning • Lack of what-if analysis in variety product mix situation • Provide what-if analysis capability • Lack of detailed execution schedule • With proper modeling, provides detailed execution priority/schedule

17. Future Business Process Changes • Reduce planning cycle from a weekly to daily • Integrate all fab areas as one team and quick response for capacity allocation. • Need a flexible system for start planners for dynamic capacity situations. • Solve problems from planning system instead of execution system. • Should integrate from customer to turnkey for Virtual Fab requirement.

18. Scenario: Good individual site delivery performance but BAD overall delivery performance, due to lack of integrated manufacturing targets. Issues FABs’ MPS don’t meet CP/ATS’s delivery needs Invisibility of FABs’ planning/execution changes to CP/ATS Lack of Push/Pull mechanism for Fab lots under defined target Current Status MPS just cover Fabs only, CP/ATS MPS were generated based on current WIP Replace projected out date with scheduled out date when lots were delayed Managed manually System Solution Manage overall capacity for FABs, CPs, ATS, EBO, PC & IE Generate integrated target for Fab, CP, ATS and EBO by backward planning Update lot schedule out date for back-end stages by daily Raise demand/supply changes to drive back-end re-planning Coordinate FABs/CP/ATS/EBO planning modules for Push/Pull decision Re-plan for execution violation by weekly Example: Business analysis and solution Customer order fulfillment performance
