High Quality Content by WIKIPEDIA articles! In technology, soft lithography refers to a family of techniques for fabricating or replicating structures using "elastomeric stamps, molds, and conformable photomasks" (in the words of Rogers and Nuzzo, p. 50, as cited in "References"). It is called "soft" because it uses elastomeric materials, most notably PDMS. Soft lithography is generally used to construct features measured on the micrometer to nanometer scale. According to Rogers and Nuzzo (2005), development of soft lithography expanded rapidly during the period 1995 to 2005.
