Methods and systems for reducing the effect of vibration in a vacuum-based semiconductor handling system
Methods and systems are provided for reducing the effects of vibration in a vacuum-based semiconductor handling system, including methods and systems for tapering robotic arm components and tapering end effectors of robotic arm components to reduce vibration in the same.
1 . A system comprising a component for material handling in a semiconductor manufacturing process, the component having a taper that establishes a non-uniform cross-section that mitigates a propagation of resonant vibrations in the component.
2 . The system of claim 1 wherein the component includes an end effector.
3 . The system of claim 2 wherein a top surface of the end effector is flat.
4 . The system of claim 2 wherein a bottom surface of the end effector is tapered.
5 . The system of claim 2 wherein the end effector is made of a cast material.
6 . The system of claim 5 wherein the taper is designed into a casting for the cast material used to build the end effector.
7 . The system of claim 1 wherein the component is a robotic arm.
8 . The system of claim 1 wherein the component is a link of a robotic arm.
9 . The system of claim 7 further comprising a plurality of tapered links, at least two of the links tapered in a manner to minimize a thickness of the tapered links when the tapered links are overlapped.
10 . The system of claim 1 wherein the component includes an end effector and a robotic arm, each of the end effector and the robotic arm being tapered.
11 . A semiconductor handling method, comprising:
providing an end effector for handling a semiconductor wafer; and
tapering the end effector to reduce resonant vibrations of the end effector.
12 . The method of claim 11 further comprising constructing the end effector of aluminum silicon carbide.
13 . A semiconductor handling method comprising:
providing a robotic arm facility; and
tapering at least one link of the robotic arm facility to dampen vibrations of the robotic arm facility.
14 . The method of claim 13 further comprising constructing at least one link of the robotic arm from aluminum silicon carbide.
