Abstract:
A clutch includes a hub having a hub flange formed at a first end. The clutch further includes a clutch tube having a central aperture formed therein, a clutch tube flange, and a friction surface that is substantially planar. The central aperture is configured to receive the shaft and is substantially perpendicular to the friction surface. The clutch further includes a clutch plate having a clutch surface that is substantially planar and is in contact with the friction surface. The clutch further includes a fastener configured to couple the clutch plate to the hub; and a spring device configured to push the hub flange and the clutch tube flange away from one another and push the friction surface to contact the clutch surface.

The present disclosure provides an integrated circuit design method in many different embodiments. An exemplary IC design method comprises providing an IC design layout of a circuit in a first technology node; migrating the IC design layout of the circuit to a second technology node; applying an electrical patterning (ePatterning) modification to the migrated IC design layout according to an electrical parameter of the circuit; and thereafter fabricating a mask according to the migrated IC design layout of the circuit in the second technology node.
Abstract:
An intensity selective exposure photomask, also describes as a gradated photomask, is provided. The photomask includes a first region including a first array of sub-resolution features. The first region blocks a first percentage of the incident radiation. The photomask also includes a second region including a second array of sub-resolution features. The second region blocks a second percentage of the incident radiation different that the first percentage. Each of the features of the first and second array includes an opening disposed in an area of attenuating material.
