Abstract:
Disclosed are methods of lithography using a tip array having a plurality of pens attached to a backing layer, where the tips can comprise a metal, metalloid, and/or semi-conducting material, and the backing layer can comprise an elastomeric polymer. The tip array can be used to perform a lithography process in which the tips are coated with an ink (e.g., a patterning composition) that is deposited onto a substrate upon contact of the tip with the substrate surface. The tips can be easily leveled onto a substrate and the leveling can be monitored optically by a change in light reflection of the backing layer and/or near the vicinity of the tips upon contact of the tip to the substrate surface.

The present invention provides stretchable, and optionally printable, semiconductors and electronic circuits capable of providing good performance when stretched, compressed, flexed or otherwise deformed. Stretchable semiconductors and electronic circuits of the present invention preferred for some applications are flexible, in addition to being stretchable, and thus are capable of significant elongation, flexing, bending or other deformation along one or more axes. Further, stretchable semiconductors and electronic circuits of the present invention may be adapted to a wide range of device configurations to provide fully flexible electronic and optoelectronic devices.
