Viscoelastic Stress Relaxation Mechanisms in Molded MEMS Package Structures
Polymer viscoelastic stress relaxation in molded MEMS packages causes long-term zero-point offset drift that requires cavity isolation or baked burn-in.
Sub-Micron Thermo-Mechanical Strain Mitigation in Heterogeneous Wafer Level Encapsulated Accelerometer Arrays
Sub-micron thermo-mechanical strain in encapsulated accelerometer arrays is mitigated using central anchor suspensions, DRIE isolation trenches, and balanced wafer stacks.
Mathematical Bivariate Polynomial Matrix Fitting for Thermal Drift Compensation
Bivariate polynomial matrix fitting corrects non-linear sensor thermal drift when inputs are normalized and solved via singular value decomposition.
Anodic Glass Bonding Thermal Expansion Strain Reduction Techniques
Anodic glass bonding strain is minimized by combining matched non-linear CTE glass selection, thin compliant interlayers, and controlled cool-down ramps.
