Patent ID: 7303934

Claim:
A method for manufacturing a micro-electromechanical device ( 10 ), in which are consecutively deposited on a substrate ( 1 ) a first electroconductive layer ( 2 ) in which a first electrode ( 2 A) is formed, a first electroinsulating layer ( 3 ) of a first material, a second electroinsulating layer ( 4 ) of a second material, different from the first material, and a second electroconductive layer ( 5 ) in which a second electrode ( 5 A) lying opposite the first electrode is formed which together with the first electrode ( 2 A) and the first insulating layer ( 3 ) forms the device ( 10 ), in which after the second conductive layer ( 5 ) has been deposited, the second insulating layer ( 4 ) is removed by means of an etching agent that is selective with respect to the material of the second conductive layer ( 5 ), characterized in that for the first material and the second material are selected materials that can be etched only limitedly selectively with respect to each other and for depositing the second insulating layer ( 4 ) on top of the first insulating layer ( 3 ) a further layer ( 6 ) is deposited on top and in direct contact with the first electroinsulating layer of a further material that can be etched selectively with respect to the first material.
