Analysis of failure sources in surface-micromachined MEMS
نویسندگان
چکیده
The effect of vertical stiction, foreign particles, and etch variation on the resonant frequency of a surfacemicromachined resonator and accelerometer are presented. For each device, it is shown that misbehaviors resulting from different failure sources can overlap, exhibit dominance and combine to create behavior masking and construction. Such an analysis is essential for developing test and diagnosis methodologies for surface-micromachined MEMS.

Failure modes for stiction in surface-micromachined MEMS
Wafer-level testing of surface-micromachined sensors provides ncw challenges to the test community. Currently, there is no method available for performing direct measurements to assess faulty micromechanical structures. Most commercial methods use electrical measurements to deduce the physical source of failures in the micromechanical structure. As a result, the process of identifyang various f...
متن کاملFailure Modes in Surface Micromachined MicroElectroMechanical Actuators
In order for the rapidly emerging field of MicroElectroMechanical Systems (MEMS) to meet its extraordinary expectations regarding commercial impact, issues pertaining to how they fail must be understood. We identify failure modes common to a broad range of MEMS actuators, including adhesion (stiction) and friction-induced failures caused by improper operational methods, mechanical instabilities...
متن کاملUncertainty in Manufacture and Assembly of Multiple-Joint Solder Self-Assembled Microelectromechanical Systems (MEMS)
Surface-micromachined microelectromechanical systems (MEMS) are two dimensional in their “as fabricated” form. Surface-micromachined MEMS can be assembled after fabrication to realize systems with a more three-dimensional form and function. One reliable method of assembly, suited to commercial mass production, is to use the surface tension of microsized droplets of molten solder to assemble the...

This paper describes the design and design issues associated with silicon surface micromachined device design. Some of the tools described are adaptations of macro analysis tools. Design issues in the microdomain differ greatly from design issues encountered in the macrodomain. Microdomain forces caused by electrostatic attraction, surface tension, Van der Walls forces, and others can be more s...
متن کاملOnset voltage modeling of micromachined colloid thrusters
The onset voltage of a colloid thruster is an important parameter in the design of micromachined thrusters. Because dimensions in MEMS thrusters are in the range of several tens of micrometers and because extractor electrodes can be only 5 μm from the capillary emitters, the aspect ratios for MEMS thrusters are much lower than the one of individual stainless steel or silica glass needles. There...
