Abstract
In one embodiment, a microreplication tool includes gas release features that allow gas to escape from microreplication cavities of the tool. The gas release features can be disposed at the bottoms of the respective cavities to avoid air entrapment within the cavities of the tool during the microreplication process. In this manner, the quality of the microreplicated product can be improved.
