Abstract:
1. A method for producing a micro-electromechanical device in a material substrate suitable for producing integrated electronic components, in particular a semiconductor substrate, wherein, in the method: the material substrate is provided, the material substrate having a surface within which at least one surface structure is formed during production of the micro-electromechanical device, wherein the surface structure comprises at least one depression having a vertical depression wall extending vertically from the surface into the material substrate, wherein a position of the at least one depression is laterally defined by a first edge defined by the depression wall and the surface; at least one electronic component is formed in the material substrate using process steps of a conventional method for producing integrated electronic components; wherein the at least one electronic component comprises a component element having a third edge which defines a position of the electronic component in a predetermined relation to the first edge; a first etching stop material acting as an etching stop for etching at least one of the material substrate or a material layer disposed on the material substrate, wherein the first etching stop material is deposited on at least one of the material substrate or the material layer on the material substrate, respectively; the first etching stop material is patterned for simultaneously forming the third edge of the component element of the at least one electronic component as well as a bounding region having a second edge extending along at least a partial section of the first edge wherein positions of the second edge and third edge have a predetermined relation relative to each other; and the material substrate thus formed is selectively etched for forming the first edge, in that the second edge of the bounding region defines, on the material substrate, a position of the first edge in a predetermined relation to the third edge of the component element of the at least one electronic component.
