Abstract
A device for manufacturing microstructures including a permeable template, wherein the template comprises at least one recess for manufacturing the microstructures. In addition, the device comprises a vacuum-generating device connected to the template such that a vacuum is applied to at least one side of the template. Further, a method for filling a permeable template, wherein the template comprises at least one recess for manufacturing microstructures. The method comprises feeding the at least one substance to be filled in to the template as well as generating a vacuum on at least one side of the template
Claims19
A device for manufacturing microstructures comprising:
- at least one permeable gas-transmissible template;
- a vacuum chamber connected to the at least one permeable gas-transmissible template, wherein the vacuum chamber is configured such that the vacuum chamber at least temporarily maintains by itself an externally generated vacuum, and wherein the vacuum chamber comprises at least one vacuum chamber opening for connecting to a pump for generating a vacuum in the vacuum chamber;
- and
- at least one self-closing valve for closing the at least one vacuum chamber opening such that an existing pressure ratio inside the vacuum chamber is maintained,
- wherein the at least one permeable gas-transmissible template comprises at least one conical recess for manufacturing the microstructures,
- wherein the pump is connected to the at least one permeable gas-transmissible template and the vacuum chamber such that the combination of the pump and the vacuum chamber generates the vacuum, and
- wherein the vacuum is applied to at least one side of the at least one permeable gas-transmissible template.
