Abstract:
1. A device, comprising: a carrier; a first material deposited on the carrier, the first material having an elastic modulus of less than 100 MPa; a semiconductor chip placed over the first material; a second material deposited on the semiconductor chip, the second material being electrically insulating; a metal layer placed over the second material, the metal layer comprising an electrically conductive line having a first end and a second end, a length of the electrically conductive line from the first end to the second end extending along an outer surface of the second material, the second end forming an external contact pad, and a portion of the electrically conductive line forming a wave shaped structure with at least two peaks and a peak-to-peak distance in the range between 10 μm and 100 μm; and a via extending orthogonally to an active main surface of the semiconductor chip through the second material, which couples a contact element of the semiconductor chip to the first end of the electrically conductive line, the via containing a solder material, wherein the second material has an elastic modulus of less than 100 MPa.
