چکیده

Dry film photoresist is used for creating microfluidic structures by sandwiching the patterned resist in between of two substrates. The technique is applied for creating hybrid biochips for dielectrophoretic cell manipulation. Multiple level lithography is demonstrated and biocompatibility of the resist is proven. Due to simple fabrication procedures the resist can be processed in a low-tech environment.

Opportunities for SUEX dry laminate resist in microfluidic MEMS applications

Microfluidics applications can benefit from a dry film approach in multiple ways – particularly in the preparation of multi-layer, multi-level fluidic channels and structures on patternable substrates and covers [1,2,3,4]. Of special benefit is the extreme simplicity in the use of the dry film sheets. A standard lamination approach allows one to apply the resist sheets as well as image them wit...

Laminated Dry Film Resist for Microengineering Applications

An innovative technology with a dry film resist (Riston) for use in microsystem engineering applications is presented. In view of the simplicity of forming a controllable resist thickness ( 20 100 ~n/level ), inherent planarization for multilevel processes in 3D microsystems and high, stable over-wafer thickness uniformity, we have investigated the use of dry film resists to realise high aspect...

Softbake of Photoresist Films

After coating, the resist film contains a remaining solvent concentration depending on the resist, the solvent, the resist film thickness and the resist coating technique. The softbake reduces the remaining solvent content in order to: avoid mask contamination and/or sticking to the mask, prevent popping or foaming of the resist by N2 created during exposure, improve resist adhesion to the subs...

Rounding of Negative Dry Film Resist by Diffusive Backside Exposure Creating Rounded Channels for Pneumatic Membrane Valves

Processing of dry film resist is an easy, low-cost, and fast way to fabricate microfluidic structures. Currently, common processes are limited to creating solely rectangular channels. However, it has shown that rounded channels are necessary to ensure proper closing of pneumatic membrane valves for microfluidic devices. Here, we introduce a modification to the standard lithography process, in o...

Laser Ablation Based Fast Prototyping of Fluidic Diode and Finger-driven Microdevice for Precise Metering and Delivery of Multi-source Liquid Reagents

In this work, we report a novel method of fabricating Glass-PDMS-glass fluidic diode using CO2 laser ablation that avoids conventional laborious procedures such as spin coating and molding of PDMS. By using this type of fluidic diode we constructed a finger-driven microdevice that can meter and deliver (MAD) multiple solutions in parallel, and the efficiency and accuracy of the MAD function was...
