In Situ Fabricated Microchannels Using Porous Polymer and Xenon Difluoride Etchant
نویسندگان
چکیده
A novel microfluidic fabrication technique which allows in situ formed silicon microchannels and does not necessitate substrate bonding is presented. A gas-permeable polymer membrane acts as the top surface of the microchannel, allowing xenon difluoride (XeF2) etchant to pass unobstructed to the silicon substrate. Exposed silicon areas on the wafer are then etched isotropically.

Monolithic multiple axis accelerometer design in standard CMOS
Using a single maskless postprocessing step we have developed an accelerometer in a standard commercial CMOS process capable of a sensitive axis parallel or perpendicular to the die surface. Our postprocess is realized using xenon difluoride (XeF2) as a bulk etchant. The combination of this etchant and the standard CMOS process allows realization of cantilevers with piezoresistive sensors in al...
متن کاملInvestigation of Functional Electrospun Bionanofibers in Microfluidic Channels
In this study, we investigated the incorporation of poly(vinyl alcohol) (PVA) nanofibers within poly(methyl methacrylate) (PMMA) microchannels in order to allow for sample preparation and concentration within microfluidic detection systems. Nanofibers were electrospun onto gold microelectrodes and integrated into polymer microfluidic systems using ultraviolet (UV)-assisted thermal bonding. We d...
متن کاملIn-situ Fabrication of Dialysis Membranes in Glass Microchannels Using Laser-induced Phase-Separation Polymerization
Laser-induced phase-separation polymerization of a porous acrylate polymer is used for in-situ fabrication of dialysis membranes inside glass microchannels. A shaped 355 nm laser beam is used to define polymer membranes of 4-14 μm thickness, which bond to the glass microchannel and form a semipermeable membrane. Differential diffusion through the membrane is observed for fluorescein molecules v...

Samples of 53 materials that are used or potentially can be used or in the fabrication of microelectromechanical systems and integrated circuits were prepared: single-crystal silicon with two doping levels, polycrystalline silicon with two doping levels, polycrystalline germanium, polycrystalline SiGe, graphite, fused quartz, Pyrex 7740, nine other preparations of silicon dioxide, four preparat...
متن کاملEx Situ Integration of Multifunctional Porous Polymer Monoliths into Thermoplastic Microfluidic Chips.
A unique method for incorporating functional porous polymer monolith elements into thermoplastic microfluidic chips is described. Monolith elements are formed in a microfabricated mold, rather than within the microchannels, and chemically functionalized off chip before insertion into solvent-softened thermoplastic microchannels during chip assembly. Because monoliths may be trimmed prior to fin...
