Abstract:
The present invention provides improved and compositions methods for replicating substrate patterns including patterns containing irregular features. The methods of the invention involve depositing block copolymer materials on a patterned substrate and ordering components in the material to replicate the pattern. In some embodiments, ordering is facilitated through the use of blends of the copolymer material and/or configuring substrate patterns so that regions of the substrate pattern interact in a highly preferential manner with at least one of the components in the copolymer material. The invention also provides compositions containing a substrate pattern with irregular features replicated in a block copolymer material.
Abstract:
Disclosed herein are stretchable, foldable and optionally printable, processes for making devices and devices such as semiconductors, electronic circuits and components thereof that are capable of providing good performance when stretched, compressed, flexed or otherwise deformed. Strain isolation layers provide good strain isolation to functional device layers. Multilayer devices are constructed to position a neutral mechanical surface coincident or proximate to a functional layer having a material that is susceptible to strain-induced failure. Neutral mechanical surfaces are positioned by one or more layers having a property that is spatially inhomogeneous, such as by patterning any of the layers of the multilayer device.
Abstract:
In an aspect, the present invention provides stretchable, and optionally printable, components such as semiconductors and electronic circuits capable of providing good performance when stretched, compressed, flexed or otherwise deformed, and related methods of making or tuning such stretchable components. Stretchable semiconductors and electronic circuits 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 are adapted to a wide range of device configurations to provide fully flexible electronic and optoelectronic devices.
Abstract:
Replicating substrate patterns containing irregular features by method (800) comprising: providing a patterned substrate with irregular feature(s) (801); depositing block copolymer materials on the patterned substrate (802); and ordering the block copolymer material in accordance with the underlying pattern (803). In some embodiments, ordering is facilitated through use of blends of the copolymer material and/or configuring substrate patterns so that regions of the substrate pattern interact in a highly preferential manner with at least one of the components in the copolymer material. Method (800) yields a substrate pattern with irregular features replicated in a block copolymer material.
