Abstract
In one embodiment, a tool used for creating grooves in a microreplication tool is described. The tool includes a mounting structure and a multi-tipped diamond mounted in the mounting structure. The different tips of the diamond may correspond to different grooves to be created in the microreplication tool. In this manner, the creation of a microreplication tool using a diamond can be simplified and/or improved.
Claims16
A method comprising:
- defining features to be created in a microreplication tool;
- creating a specification for a diamond, wherein the specification defines multiple tips that correspond to the features to be created in the microreplication tool;
- focused ion beam milling the diamond to have multiple tips according to the specification;
- and
- creating the microreplication tool using the ion beam milled diamond, wherein creating the microreplication tool comprises cutting a number of grooves in the tool with a number of passes of the ion beam milled diamond, wherein the number of grooves is greater than the number of passes.
