A Substrate-independent Wafer Transfer Technique for Surface-micromachined Devices
نویسندگان
چکیده
We report on a new wafer transfer technique that can remove and transfer surface-micromachined layers to application-specific substrates. This process, however, is not limited to only MEMS devices and can be applicable to other semiconductor devices. Successful transfer of a 1 cm x 1 cm MEMS chip with electrostatically actuated curled cantilever switches to a transparent quartz substrate has been demonstrated. Pull-in voltage for transferred devices is 31 V compared with 23 V for devices on standard silicon substrates.

Two-stage polymer embossing of co-planar microfluidic features for microfluidic devices
A two-stage embossing technique for fabricating microchannels for microfluidic devices is presented. A micromachined aluminum mold is used o emboss a polyetherimide (PEI) substrate with a relatively high glass transition temperature (T ). The embossed PEI is then used as a mold for g mbossing an amorphous polyethylene terephthalate (APET) substrate with a lower Tg. The resulting APET substrate ...

متن کاملEfficient tools for the design and simulation of microelectromechanical and microfluidic systems
In air-packaged surface micromachined devices and microfluidic devices the surface to volume ratio is such that drag forces play a very important role in device behavior and performance. Especially for surface micromachined devices, the amount of drag is greatly influenced by the presence of the nearby substrate. In this thesis a precorrected FFT accelerated boundary element method specialized ...
