Abstract: A device for at least emptying a transport container having a stack of plate-shaped items, including semiconductor wafers and/or packaging material, includes at least one measuring device and a holder at least part of which can travel into the transport container. The holder has a holding surface, a number of holding nozzles for at least holding an item in the stack, and, in the region of the holding surface, at least one recess for the measuring device for acquiring measurement data from the item in the stack. At least one separating nozzle is arranged on the holder outside the holding surface such that the nozzle(s) can move between rest and separating positions. In the separating position, a gas stream directed towards the end face of the stack is formed, to release at least one item in the stack that is adhered to the item held by the holder.

Abstract: An apparatus, in particular end effector, for receiving, transporting and/or positioning a wafer frame which is covered by a carrier film for carrying a wafer, has a holder which has vacuum nozzles for holding the wafer frame on the apparatus, and has a centering device which has at least one stop, which can engage in a cutout in the wafer frame, for centering the wafer frame. In order to precisely position the wafer frame, the holder has Bernoulli nozzles for holding and moving the wafer frame in the direction of the stop without contact, and the stop is mounted such that it can be adjusted against the movement direction generated by the Bernoulli nozzles from an initial position to a centering position, which differs from the initial position, for centering the wafer frame.
