Abstract
The present invention relates to A microfabricated tip and post structure comprising a post having a rough top surface that diffuses incident light and a cross-section, and a tip, lithographically plated on the rough top surface of the post, having a smooth reflective surface appropriate for automatic vision recognition, and having a cross-section that is less than the cross-section of the post.
Claims28
A microfabricated structure, comprising:
- a post having a rough top surface with a surface area and the top surface having a property of diffusing, diffracting, or absorbing incident light;
- and
- a tip, lithographically pattern-plated on the rough top surface of the post, having a smooth reflective surface suitable for machine recognition systems, and having a contact surface area that is less than the surface area of the top surface of the post.
12-18. (canceled)
A microfabricated structure, comprising:
- a post having a top surface with an area;
- a tip having side walls and a top surface, said top surface having a smooth reflective surface appropriate for machine vision recognition of tip position and size, said tip being plated on the top surface of the post, and having an area less than the area of the top surface of the post such that once plated on the top surface, the top surface has an exposed portion and an unexposed portion;
- and
- a skirt plated over the exposed portion of the top surface of the post and over at least a portion of the side walls of the tip, said skirt having a property of at least one of diffusing, diffracting or absorbing light.
26-32. (canceled)
A microfabricated structure comprising a tip lithographically pattern-plated on a post, wherein the tip has a smooth surface suitable for automatic vision recognition and the post has a surface that has at least one property that aids an automatic vision recognition system in identifying the tip.
