Abstract
For manufacturing a sound transducer structure, membrane support material is applied on a first main surface of a membrane carrier material and membrane material is applied in a sound transducing region and an edge region on a surface of the membrane support material. In addition, counter electrode support material is applied on a surface of the membrane material and recesses are formed in the sound transducing region of the membrane material. Counter electrode material is applied to the counter electrode support material and membrane carrier material and membrane support material are removed in the sound transducing region to the membrane material.
