Abstract:
A method for producing a MEMS sound transducer element includes, inter alia, providing a first substrate. The first substrate has a first substrate side, an opposite second substrate side and a membrane layer arranged on the first substrate side. A further method step includes performing a first etching from the second substrate side in a first surface section that is situated opposite the membrane layer, as far as a first depth. A further method step includes performing a second etching of the first substrate from the second substrate side in a second surface section in order to expose the membrane layer in the first surface section and to produce a back volume for the membrane layer, where the second surface section is larger than the first surface section and includes the first surface section.

Claim (Index 4):
The method as claimed in  claim 1 , wherein, before the second etching, arranging a second etching mask on the second substrate side, wherein the second etching mask surrounds the second surface section, and wherein the second etching is effected using the second etching mask.
