Diamond tool with a multi-tipped diamond
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.
1. 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.
2. The method of claim 1 , further comprising:
processing the diamond prior to focused ion beam milling the diamond to reduce the amount of focused ion beam milling required to form the multiple tips according to the specification.
3. The method of claim 1 , wherein the multiple tips include two tips.
4. The method of claim 3 , wherein a valley between the two tips defines a bottom surface selected from the following group: a convex arc shaped surface, a concave arc shaped surface, and a flat surface.
5. The method of claim 1 , wherein a pitch spacing between two neighboring tips is less than approximately 500 microns.
6. The method of claim 5 , wherein the pitch spacing is less than approximately 200 microns.
7. The method of claim 6 , wherein the pitch spacing is less than approximately 100 microns.
8. The method of claim 7 , wherein the pitch spacing is less than approximately 10 microns.
9. The method of claim 8 , wherein the pitch spacing is less than approximately 1 micron.
10. The method of claim 9 , wherein the pitch spacing is less than approximately 0.1 micron.
11. The method of claim 1 , wherein an aspect ratio of a height of a respective tip relative to a width of the respective tip is greater than approximately 1 to 1.
12. The method of claim 1 , wherein an aspect ratio of a height of a respective tip relative to a width of the respective tip is greater than approximately 2 to 1.
13. The method of claim 1 , wherein the multiple tips define a width of less than approximately 200 microns.
14. The method of claim 1 , wherein the multiple tips each define substantially straight side walls and wherein a bottom of a valley formed by neighboring tips approximately defines a right angle relative to the side walls.
15. The method of claim 1 , wherein the multiple tips each define undercut side walls and wherein a bottom of a valley formed by neighboring tips defines an acute angle relative to the undercut side walls.
16. The method of claim 1 , wherein the multiple tips each define side walls and wherein a bottom of a valley formed by neighboring tips defines an obtuse angle relative to side walls.
