Introduction
Microelectro-mechanical systems are being utilized for a variety of applications such as microfluidic pumps, micromirror display devices, and acceleration and pressure sensors. The MEMS units extend the fabrication techniques utilized in the IC industry to produce mechanical components such as connecting beams, diaphragms, and gears. Precise measurement of these components is crucial in being able to satisfy the increasing demand for high-quality, low-cost MEMS units.
Metrology
Roughness Measurement
Measuring the roughness within MEMS units enables control of surface interactions, irrespective of whether they are solid to liquid interactions or solid to solid interactions. Solid to liquid interactions are encountered in microfluid pumps whereas solid to solid interactions are common in microgear systems.
Monitoring Step Height
Step height measurement of MEMS units is crucial for monitoring the performance of the device. Step height, in addition to providing lateral dimension information, also provides good mass approximation that impacts the oscillating frequency of the components present in the device.
