Conforming template for patterning liquids disposed on substrates
View Patent ↗The present invention includes a template for patterning liquids disposed on a substrate. The template includes a body having opposed first and second surfaces with one surface having at least one recess and the other surface having a patterning region. In one embodiment, the template may be mounted to a fluid chamber having an inlet and a throughway. The template may be connected to the throughway and the inlet is connected to a fluid source.
1. A system comprising:
a substrate having a plurality of droplets positioned thereon;
a mold assembly, spaced-apart from the substrate, for imprinting a pattern in a deformable material, the mold assembly having first and second surfaces, with the first surface including at least one recessed region and the second surface defining a patterning region configured to provide the pattern in the deformable material;
a mold deformation enabling apparatus coupled to the mold assembly to facilitate deformation of the mold assembly to conform to a layer formed from the plurality of droplets, wherein the mold deformation enabling apparatus includes a chamber having an inlet and a throughway, with the mold assembly being connected to the throughway; and,
a source of fluid in fluid communication with chamber through the inlet, varying pressure at the recessed region.
2. The system as recited in claim 1 , wherein the chamber includes a plurality of walls, with the plurality of walls being more rigid than the mold assembly.
3. The system as recited in claim 1 , wherein the patterning region has a profile selected from a set of profiles including smooth, planar, and patterned.
4. The system as recited in claim 1 , wherein the patterning region covers an area of the second surface that has a polygonal shape.
5. The system as recited in claim 1 , further including a plurality of the patterning regions arranged in a two-dimensional array.
6. The system as recited in claim 1 , wherein the pattern includes a plurality of protrusions and recessions having submicron dimensions.
7. A system comprising:
a mold assembly for imprinting a pattern in a deformable material, the mold assembly having first and second surfaces, with the first surface including at least one recessed region and the second surface defining a patterning region configured to provide the pattern in the deformable material;
a mold deformation enabling apparatus coupled to the mold assembly to facilitate deformation of the mold assembly to conform to a profile of a surface adjacent to the mold assembly, wherein the mold deformation enabling apparatus includes a chamber having an inlet and a throughway, with the mold assembly being connected to the throughway; and,
a source of fluid in fluid communication with chamber through the inlet, varying pressure at the recessed region.
8. The system as recited in claim 7 , wherein the surface further includes a plurality of spaced-apart droplets positioned thereon.
9. The system as recited in claim 7 , wherein the chamber includes a plurality of walls.
10. The system as recited in claim 9 , wherein the plurality of walls is more rigid than the mold assembly.
11. The system as recited in claim 7 , wherein the patterning region is patterned.
12. The system as recited in claim 7 , wherein the patterning region is planar.
13. The system as recited in claim 7 , wherein a portion of the patterning region is patterned and a portion of the patterning region is planar.
14. The system as recited in claim 7 , wherein the patterning region covers an area of the second surface that has a polygonal shape.
15. The system as recited in claim 7 , further including a plurality of the patterning regions arranged in a two-dimensional array.
16. The system as recited in claim 7 , wherein the pattern includes a plurality of protrusions and recessions.
17. The system as recited in claim 16 , wherein the plurality of protrusions and recessions have submicron dimensions.
18. A system comprising:
a substrate having a plurality of droplets positioned thereon;
a mold assembly, spaced-apart from the substrate, for imprinting a pattern in a deformable material, the mold assembly having first and second surfaces, with the first surface including at least one recessed region and the second surface defining a patterning region configured to provide the pattern in the deformable material;
a chamber having an inlet and a throughway, with the template being connected to the throughway to facilitate deformation of the mold assembly to conform to a layer formed from the plurality of droplets;
a source of fluid in fluid communication with the chamber through the inlet, varying pressure at the recessed region; and
a source of radiation to impinge actinic radiation upon the layer.
19. The system as recited in claim 18 , wherein the chamber includes a plurality of walls, with the plurality of walls being more rigid than the mold assembly.
20. The system as recited in claim 18 , wherein the patterning region has a profile selected from a set of profiles including smooth, planar, and patterned.
