Module 1.1

Role of Wafer Probe in Sensor Manufacturing

Before dicing and expensive packaging, wafer probing identifies defective die to ensure only known-good dies (KGD) proceed to final assembly.

ATE testers supply power, calibrate on-chip voltage regulators, verify digital I2C/SPI interfaces, and test analog front-end amplifiers.

  • Role of Wafer Probe in Sensor Manufacturing: Fundamental process parameter dictating sensor sensitivity, signal-to-noise ratio, and mechanical stability.
  • Process Window Optimization: Maximizing lithography, plasma etch, sacrificial release, and bonding margins across 200mm/300mm MEMS fabs.
  • Stress & Defect Mitigation: Eliminating film stress gradients to prevent out-of-plane mechanical beam warping and comb finger shorting.
  • Transducer Efficiency: Optimizing capacitive sense area, piezoresistive gauge factors, or photon absorption depth.

Module 1.2

Testing the CMOS Readout Circuitry (FEOL/BEOL)

ATE testers supply power, calibrate on-chip voltage regulators, verify digital I2C/SPI interfaces, and test analog front-end amplifiers.

Because wafers are flat on a chuck, mechanical stimulation is difficult; applying on-chip electrostatic voltages pulls the proof mass to verify electromechanical response.

  • Testing the CMOS Readout Circuitry (FEOL/BEOL): Real-time optical emission spectroscopy, laser interferometer endpoint tracking, and high-vacuum robotic handling.
  • Thermal Budget & Interface Integrity: Protecting underlying CMOS electronics during MEMS structural anneals and wafer bonding cycles.
  • Micro-Cavity Vacuum Preservation: Activating non-evaporable getters to maintain sub-mbar cavity pressures for high-Q gyroscopes.
  • Yield Impact: Direct correlation between unit-step CD uniformity, stiction-free drying, and functional sensor die per wafer (DPW).

Electrostatic Built-In Self-Test (BIST)

Because wafers are flat on a chuck, mechanical stimulation is difficult; applying on-chip electrostatic voltages pulls the proof mass to verify electromechanical response.

Before dicing and expensive packaging, wafer probing identifies defective die to ensure only known-good dies (KGD) proceed to final assembly.
