Patent ID: 8530855

Claim:
A method for producing a micro-gripper for clamping a micrometer-scale or sub-micrometer-scale object in a receptacle slot for gripping and holding between a first gripping element and a second gripping element, the method comprising the steps: providing a flat substrate; applying a first sacrificial layer over the flat substrate; forming the first gripping element by applying at least one first material layer to the first sacrificial layer; applying a second sacrificial layer to an area of the first material layer at least in an area where the receptacle slot is to be formed; forming the second gripping element by applying a second material layer to the second sacrificial layer in the area where the slot is to be formed and forming a base body of the micro-gripper by applying the second material layer to an area of the first material layer to bond the first material layer to the second material layer; removing the second sacrificial layer to provide the receptacle slot with free ends respectively comprising the first and second material layers with the receptacle slot being provided between the first material layer and the second material layer; and removing an area of the first sacrificial layer to detach the micro-gripper from the flat substrate.
