Job description

  • Your mission will be to define and coordinate the development and integration of multi die stacking approaches (2D, 2.5D, 3D). You will explore different die-to-die (D2D), die-to-wafer (D2W) and collective die-to-wafer (C2W) thermocompression bonding (TCB) schemes. You will review the  impact of these schemes on the overall needs of the 3D program.
  • You plan development activities for the process module assigned to you. You will follow-up on the processing (at both wafer and die level) of test material, collect and analyze performance data. You report results both internally as well as to customers. You will be supported in your task by a Process Assistant, but will be expected to take a significant hands on role within the clean room.
