Patent ID: 7669310

Claim:
A method of manufacturing an acoustic mirror, the method comprising: (a) providing a basic material having a first layer of a layer sequence on the basic material; (b) applying a second layer of the layer sequence on the first layer, the second layer of the layer sequence partially covering the first layer, the first layer and the second layer providing a layer sequence of alternately arranged layers of high acoustic impedance and low acoustic impedance, wherein the first and second layers are arranged in parallel in relation to a common layer plane; (c) applying a planarization layer on the layer sequence; (d) removing the planarization layer in an area which, in relation to the common layer plane, projects outward beyond the second layer, wherein removal of the planarization layer in the area results in a residual planarization layer comprising a pit; and (e) applying a termination layer onto the layer sequence and the residual planarization layer.
