1 Collaborative Alliance for Semiconductor Test (CAST) Special Interest Group CAST Overview 2017

2 CAST Charter A SEMI Special Interest Group that develops, coordinates, and directs all SEMI services for the semiconductor test community. Charter includes: Foster pre-competitive collaboration Research, develop and promote standards that enable industry productivity improvements Perform pre-competitive benchmarks Act as a representative and an advocate for the members 2

3 CAST Strategic Direction Inspired by the ITRS Roadmap Focused on areas identified as challenges and for which no known solution is existing or for which solutions are desirable. CAST role is to Put the relevant actors/technical leaders together Formulate options Define guidelines leading to standards Undertake/Sponsor pre-competitive initiatives Working groups have been set up on Test Cell Communications and Test Data Standards. 3

4 CAST Membership Benefits Influence technology direction Networking in a non-competitive environment Professional development Industry recognition (company & individual) Leverage industry-wide resources Membership: SEMI members No fees Submit CAST membership application Designate representatives to serve in the steering committee and in the working group(s) Voting CAST Customer Advisory Panel (CAP) members Open to chipmakers No fees Non-voting
