About the role

Foundry Interface Engineer to collaborate with Foundry partners, internal teams, and OSAT to optimize ASIC design, wafer test data analysis, and process fine-tuning to meet technology entitlement and product goals.

Responsibilities

  • Review and assess Foundry silicon data against SPICE/design goals and compile SPICE to Silicon gap analysis.
  • Drive foundry partners on CIP s to improve foundry process to meet technology entitlement and product goals.
  • Work with foundry to identify potential device parameter changes to enable efficient low-voltage operation
  • Work closely with circuit designers to determine what device improvements could improve circuit performance and energy efficiency
  • Engage with Foundry partners/third-party vendors to manage foundry PDK/DK and design library collaterals
  • Guide internal IP/design teams on appropriate usage of technology attributes/offerings in accordance with product requirements (e.g., performance, power, area, and cost).
  • Collaborate with internal third-party infrastructure, customization, test-chip, methodology, and packaging and product test engineering teams for seamless execution of product bring-up and productization.
  • Work with test engineers to analyze and validate production wafer data
  • Contribute to binning strategy to maximize parametric yield

Qualifications

  • 10 + years of post-education experience in FAB/Fabless environments, technology definition and bring-up, device/process architecture, and NPI
  • Experience with foundry design kit, SPICE, DR/DRC evaluation, SPICE to Si assessment
  • Experience with advanced node device physics (e.g. FinFET/GAA), backside power, product design phases
  • Experience with product KPIs, DTCO, and parametric, DLY/PLY analysis/gap closure
  • Understanding of low power design techniques (e.g., Vmin reduction, power gating, multi-voltage design, chip power, clock network and optimization)
  • Understanding of layout effects and impact to circuit design
