Patent ID: 8714611

Claim:
Handling device for handling of a wafer in the processing of the wafer, the device comprising: a carrier having a receiving side for holding the wafer, the receiving side including a flat central portion, a grid structure disposed on the receiving side of the carrier around an outer periphery of the flat central portion of the receiving side, the grid structure having an upper surface raised above the flat central portion of the receiving side of the carrier, and a flexible cover for fixing the wafer on the carrier, the cover disposed over the grid structure and covering the upper surface of the grid structure such that the flexible cover, the grid structure and the carrier define a grid space, the grid space being fluidly connected to a source of negative pressure for detaching the wafer from the carrier, wherein the grid structure and the flat central portion of the receiving side of the carrier define a trough-shaped receiving space dimensioned for receiving structures which are disposed on the wafer and which are raised relative to a wafer receiving side of the wafer such that the structures on the wafer are fluidly isolated from a surrounding environment when the wafer is attached to the receiving side of the carrier.
