A spool handling device for engaging and disengaging a spool having, a base, a spindle supported by the base and adapted to receive the spool, a latch assembly pivotally mounted relative to the base and including a latch for releasably securing the spool on the spindle, and an ejection arm for assisting in removal of the spool from the spindle. A silicon oxide film, a polysilicon film and a silicon oxide film are formed in the order named on a silicon substrate. A second method also creates a synthesized texture image guided by a first and second sample textures and corresponding first and second texton masks. The response includes UL resource allocation information for scheduling an UL transmission. The method and system specify a position for measuring a difference between a lithography image and a target pattern, generate one or more CD marker candidates, and select at least one CD marker from the one or more CD marker candidates.
