This paper reports the initial characterization of the sensor, including rotation and vibration tests. Initial results indicate that this piezoresistive sensor is capable of wirelessly measuring rotation speeds at /spl sim/2Hz/rpm/V with 5V input in the 100 to 6000 rpm rotation range. We believe our groundwork will allow the MEMS community to use the MUMPs foundry service to design simple and reliable high-speed rotation sensors that can be interfaced with commercial wireless chips for signal transmission.","PeriodicalId":251857,"journal":{"name":"Proceedings IEEE Thirteenth Annual International Conference on Micro Electro Mechanical Systems (Cat.

The transferred relays include a variety of electrostatic pull-down type structures, as well as see-saw type structures. The batch-transfer methodology allows integration of optimized MEMS in RF systems on substrates such as sapphire, GaAs, and even CMOS. Gold-to-gold contact series microrelays with insertion loss of <0.15 dB, and isolation better than 36 dB at frequencies from 45 MHz to 40.0 GHz are demonstrated, as well as shunt switches with >40 dB of isolation and <0.12 dB insertion loss in that frequency range. A novel device structure which combines the benefits of see-saw operation and both shunt and series switching was shown to improve isolation of a single switch by /spl sim/8 dB while maintaining low insertion loss.","PeriodicalId":251857,"journal":{"name":"Proceedings IEEE Thirteenth Annual International Conference on Micro Electro Mechanical Systems (Cat.

The newly developed structure combines two moving mirrors and a fixed V mirror to implement a 2/spl times/2 micro-optical switch with uni-directional input/output. Furthermore, the moving mirrors have been reduced in size by integrating the drive and latch functions by the use of magnetic shaft mirrors and driving coils. The micro-optical switch has been implemented as a module mounted in a ceramic package. The modular switch is 23.5/spl times/9.86/spl times/6.76 mm in size and provides a switching time of 1.3 ms for 15 V (469 mA) and an input pulse width of 1 ms. The reflectivity of the moving mirror is 98.6% (reflection loss: 0.06 dB) and the connection loss between the fixed mirror surfaces is 5.4 dB.","PeriodicalId":251857,"journal":{"name":"Proceedings IEEE Thirteenth Annual International Conference on Micro Electro Mechanical Systems (Cat.

Silicon nitride is used in numerous MEMS applications thanks to its good mechanical and electrical properties. The SiN/sub x/ micromechanical structures usually serve as supporting elements such as membranes, plates and cantilevers. A new failure mechanism is found in thin resonating SiN/sub x/ structures operating in air. The stiffness of the structure is changing due to surface oxidation. The surface oxide layer can crack and recover during operation of the device. This results in unstable resonance frequency and failure of the resonant mode MEMS device.","PeriodicalId":251857,"journal":{"name":"Proceedings IEEE Thirteenth Annual International Conference on Micro Electro Mechanical Systems (Cat.

We have systematically investigated the influence of different bonding parameters on void formation in the bond. The layer thicknesses of the tested polymer coatings are between 1 /spl mu/m and 12 /spl mu/m. The polymer material, the bonding pressure and the pre-curing time and temperature for the polymer has shown significant influence on void formation in the bond. High bonding pressure and pre-curing times/temperatures that are specific to the polymer material counteract void formation. Process parameters for achieving void-free bonds using benzocyclobutene (BCB) and photoresist coatings as adhesive materials are given. Excellent bonding results have been achieved with BCB as bonding material.","PeriodicalId":251857,"journal":{"name":"Proceedings IEEE Thirteenth Annual International Conference on Micro Electro Mechanical Systems (Cat.
