摘要:
Additive repair of advanced photomasks with low temperature or optical curing via direct write lithographic printing with sharp tips and cantilevers. The optical properties of the materials formed from the ink can be tuned (e.g., n and k values). Sol gel inks, including silsesquioxane inks, can be used to form MoSi compositions. The repaired photomasks are resistant to washing under normal photomask washing conditions. AFM instrumentation can be used to perform the additive repair to provide the high resolution and registration.

Inkwells adapted for use in direct-write nanolithography and other applications including use of wells, channels, and posts. The wells can possess a geometry which matches the geometry of tips which are dipped into the inkwells. The channels can be open or closed. Hydrophilicity and hydrophobicity can be used to control ink flow. SEM can be used to characterize the inkwells. Ink flow can be monitored with video. Hydrophobic material layers can be used to prevent cross contamination. Microsyringes can be used to fill reservoirs. Satellite reservoirs can be used to prevent bubble formation.
摘要:
Massive parallel printing of structures and nanostructures at high speed with high resolution and high quality using two dimensional arrays comprising cantilevers and tip-based transfer of material to a surface. The array is designed so only tips touch the surface. This can be accomplished by long tips and bent cantilevers and alignment. An article comprising: a two-dimensional array of a plurality of cantilevers, wherein the array comprises a plurality of base rows, each base row comprising a plurality of cantilevers, wherein each of the cantilevers comprise tips at the cantilever end away from the base, wherein the number of cantilevers is greater than 250, and wherein the tips have an apex height relative to the cantilever of at least four microns, and a support for the array. Combinatorial arrays and bioarrays can be prepared. The arrays can be manufactured by micromachining methods.

摘要:
Cantilever design for patterning from a cantilever tip can be improved with, for example, a recessed area surrounding the cantilever tip. A device for printing nanoscopic and microscopic patterns includes at least one cantilever having a front surface, a first side edge, a second side edge, and a first end which is a free end and a second end which is a non-free end. The front surface includes at least one first sidewall disposed at the first cantilever side edge and at least one second sidewall disposed at the second cantilever side edge opposing the first cantilever side edge, at least one channel, adapted to hold a fluid, disposed between the first and second sidewalls, wherein the channel, the first sidewall, and the second sidewall extend toward the cantilever free end but do not reach the free end, and a base region having a boundary defined by the first edge, the second edge, and the cantilever free end and also the first sidewall, second sidewall, and the channel, wherein the base region comprises a tip extending away from the cantilever front surface. Improved deposition can result. Fluidic inks comprising biomolecules can be patterned successfully.
