Week Course Content
Week 1 Study the mechanical structure of existing ST MEMS accelerometers (e.g., LSM303AGR, mass-spring system).
Week 2 Design a cantilever structure adhering to1P6M design rules (e.g., minimum line width, interlayer dielectric materials) using finite element analyses.
Week 3 Simulate mechanical sensitivity (e.g., displacement vs. acceleration) and resonant frequency.
Week 4 3D model of the MEMS structure and simulation report (including stress analysis).
Week 5 Design a capacitive sensing circuit (e.g., differential capacitance-to-voltage converter), considering UMC 1P6M analog circuit constraints (e.g., parasitic capacitance).
Week 6 Use spice for circuit design and perform co-simulation with the MEMS structure using matlab.
Week 7 Optimize noise performance and signal chain (e.g., chopper stabilization).
Week 8 Circuit schematic and post-layout simulation results.
Week 9 Integrate MEMS and circuit layouts (GDSII file) and verify DRC/LVS using PDK.
Week 10 Propose a mock-up test plan (e.g., via TSRI’s MPW service).
Week 11 validate performance using Finite Element Analysis (FEA).
Week 12 validate performance using Finite Element Analysis (FEA).
Week 13 validate performance using Finite Element Analysis (FEA).
