摘要:
The present invention concerns a MEMS device comprising an under bump metallization (4)—UBM—to contact the device via flip-chip bonding with a substrate. The UBM (4) is placed on the surface of the MEMS device and close to the corners of the surface. Further, the shape of the UBM (4) is adapted to the shape of the corners.
