Abstract: Some embodiments of the present disclosure relate to a processing tool. The tool includes a housing enclosing a processing chamber, and an input/output port configured to pass a wafer through the housing into and out of the processing chamber. A back-side macro-inspection system is arranged within the processing chamber and is configured to image a back side of the wafer. A front-side macro-inspection system is arranged within the processing chamber and is configured to image a front side of the wafer according to a first image resolution. A front-side micro-inspection system is arranged within the processing chamber and is configured to image the front side of the wafer according to a second image resolution which is higher than the first image resolution.

Abstract: A collapsing device for a stroller is provided, including a framework consisting of two front feet, two rear feet, a lying frame, an extended frame and an inverted U-shaped handle pivotally combined with the front and rear feet. When a pusher unit fixed on the handle is pressed, the extended frame supporting a canopy is swung down to a collapsed position to lie on the lying frame. Then, the handle is swung down, with two connecters functioning as pivots for the handle to permit the handle to disengage from the front feet in moving to the collapsed position, responsive to a contact member of each connecter respectively separating from upper ends of the two front feet.
