Abstract
A MEMS-transducer comprises a membrane structure having a first main surface and a second main surface opposing the first main surface. A substrate structure holds the membrane structure, wherein the substrate structure overlaps with the first main surface of the membrane structure in a first edge region being adjacent to a first inner region of the first main surface. A gap is formed between the membrane structure and the substrate structure in the first edge region and extends from the first inner region into the first edge region.
