Molding replica

A rich variety of materials (including precursors) have been incorporated into the template-directed synthesis.33 169 170 Curable liquid prepolymers are particularly attractive because they have been widely used in replica molding with resolutions better than a few nanometers. By judicially selecting a monomer, the volume shrinkage involved in... 

The device was fabricated using standard lithographic and replica molding methods [162].

Figure 6.65. Comparison of (a) conventional photolithography/electroplating with (b) soft lithography. Shown in (b) is replica molding which consists of the formation of a PDMS stamp, and subsequent replication of a master in a photo- or thermally curable prepoiymer.
