Fabrication Process and Technologies
The manufacturing process combines precision engineering with semiconducting techniques:
The manufacturing process combines precision engineering with semiconducting techniques:
- Core Technologies: Bulk micromachining is the most established technique, while surface micromachining is also used.
- Key Processes: Photolithography, wet and dry etching, oxidation, diffusion, and low-pressure chemical vapor deposition (LPCVD).
- Specific Techniques: Deep Reactive Ion Etching (DRIE) of silicon and wafer bonding are crucial for creating robust, high-sensitivity 3D structures.
- Materials: Single crystal silicon and glass are often used for stability and reliability.
- Calibration: Laser trimming is used to adjust tolerances and pre-calibrate sensors during manufacturing.
Types of MEMS Accelerometers Fabricated
- Variable Capacitance (VC): High sensitivity, lower range, ideal for vibration and structural monitoring.
- Piezoresistive (PR): Lower sensitivity, higher range, used for shock and blast applications.
- Closed-Loop: High-performance devices for tactical and inertial navigation.
