Responsibilities
Collaborate with key partners and define the integrated manufacturing flow (from wafer sort through assembly, final test, system-level test) to achieve coverage, DPPM, and cost-of-test targets
Partner with Silicon Design/DFT on testability features (e.g., scan, boundary scan/JTAG, MBIST/LBIST, fuse/trim) to accelerate yield ramp and diagnostics
Coordinate ATE platform selection, test program strategy, characterization/correlation, guard-banding, PAT/outlier screening, and test-time optimization
Define and implement advanced assembly processes with OSAT partners, including wafer bump technologies and substrate manufacturing
Drive assembly process qualifications, excursions management, and continuous improvement to improve yield, reliability, and cycle time
Collaborate with substrate suppliers to enhance material quality and robustness; co-develop improvements
Establish yield roadmaps across assembly, substrate, and test based upon architecture decisions
Work with product engineering to identify gaps/issues and drive debug/resolution
Establish technical governance with assembly and substrate partners: audits, technical reviews, QBRs, SLAs, and KPIs
Drive OSAT improvement plans and ensure alignment with Ampere’s roadmap, standards, and schedules
Align with Silicon Engineering, Product/Test, Quality, NPI/Operations, Supply Chain, and FA labs on requirements, risks, and execution plans
Provide clear, data-driven updates, trade-off analyses, and risk mitigation plans to executive leadership
Define dashboards and operating mechanisms for yield, quality, cost-of-test, and cycle time
Benchmark industry practices and integrate relevant advancements in assembly, substrates, test, and analytics
