Soft Lithography

Angewandte Chemie International Edition, 1998
Abstract  Soft lithography represents a non-photolithographic strategy based on self-assembly and replica molding for carrying out micro- and nanofabrication. It provides a convenient, effective, and low-cost method for the formation and manufacturing of micro- and nanostructures.

Negative Printing by Soft Lithography

ACS Applied Materials & Interfaces, 2014
In inkless microcontact printing (IμCP) by soft lithography, the poly(dimethylsiloxane) (PDMS) stamp transfers uncured polymer to a substrate corresponding to its pattern. The spontaneous diffusion of PDMS oligomers to the surface of the stamp that gives rise to this deleterious side effect has been leveraged to fabricate a variety of devices, such as ...

Soft lithography: masters on demand

Lab on a Chip, 2008
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.

Soft Lithography of Ceramic Patterns

Advanced Functional Materials, 2007
AbstractPolymer‐based precursor solutions are patterned using a soft‐lithographic patterning technique to yield sub‐micrometer‐sized ceramic patterns. By using a polymer–metal‐nitrate solution as a lithographic resist, we demonstrate a micromolding procedure using a simple rubber stamp that yields a patterned precursor layer.

Polycarbonate Heat Molding for Soft Lithography

Small, 2020
AbstractSoft lithography enables rapid microfabrication of many types of microsystems by replica molding elastomers into master molds. However, master molds can be very costly, hard to fabricate, vulnerable to damage, and have limited casting life. Here, an approach for the multiplication of master molds into monolithic thermoplastic sheets for further

Stamp Collapse in Soft Lithography

Langmuir, 2005
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.
