A new inspection technique helps improve the surface finish of hydraulic cylinder rods, leading to dramatically longer seal life. • Cylinder rod finish can dramatically affect seal life. • Traditional ...

For decades, optical inspection has been the primary method for process control in fabs. However, the move to multi-level interconnects and 3D transistor designs means that many killer defects are no ...

During 7nm gate poly removal process, polysilicon is removed exposing both NFET and PFET fins in preparation for high-k gate oxide. If the polysilicon etch is too aggressive or the source and drain ...

In order to detect defects in the surfaces of dry fabric and composite prepreg, this new vision-based tactile sensor roller prototype, TacRoller, is a three-colour reflective membrane roller-shape ...
