Via patterning in insulating layer by soft lithography
During a six months internship, the structuring of electrical vias by direct dewetting on gold substrates patterned with microcontact printing has been explored. A high modulus polymer has been tested to avoid roof collapse during the printing of the contact holes. The dewetting behaviour of potential candidates for the dielectric layer has been investigated. Conclusions: 1. Printing of the con...
متن کاملSoft holographic interference lithography microlens for enhanced organic light emitting diode light extraction.
Very uniform 2 μm-pitch square microlens arrays (μLAs), embossed on the blank glass side of an indium-tin-oxide (ITO)-coated 1.1 mm-thick glass, are used to enhance light extraction from organic light-emitting diodes (OLEDs) by ~100%, significantly higher than enhancements reported previously. The array design and size relative to the OLED pixel size appear to be responsible for this enhancemen...
متن کاملStamp collapse in soft lithography.
We have studied the so-called roof collapse in soft lithography. Roof collapse is due to the adhesion between the PDMS stamp and substrate, and it may affect the quality of soft lithography. Our analysis accounts for the interactions of multiple punches and the effect of elastic mismatch between the PDMS stamp and substrate. A scaling law among the stamp modulus, punch height and spacing, and w...
متن کاملSoft lithography: masters on demand.
We report an ultra-rapid prototyping technique for forming microchannel networks for lab-on-a-chip applications, called masters on-demand. Channels are produced by replica molding on masters formed by laser printing on flexible copper printed circuit board (PCB) substrates. Masters of various designs and dimensions can be individually or mass produced in less than 10 minutes. Using this techniq...
متن کاملDigital microfluidics using soft lithography.
Although microfluidic chips have demonstrated basic functionality for single applications, performing varied and complex experiments on a single device is still technically challenging. While many groups have implemented control software to drive the pumps, valves, and electrodes used to manipulate fluids in microfluidic devices, a new level of programmability is needed for end users to orchest...
