Abstract: A pressure sensor device includes a semiconductor die having a die surface that includes a pressure sensitive area; and a bond wire bonded to a first peripheral region of the die surface and extends over the die surface to a second peripheral region of the die surface, wherein the pressure sensitive area is interposed between the second peripheral region and the first peripheral region, wherein the bond wire comprises a crossing portion that overlaps an area of the die surface, and wherein the crossing portion extends over the pressure sensitive area that is interposed between the first and the second peripheral regions.

Abstract: A pressure sensor device includes a semiconductor die of the pressure sensor device and a bond wire of the pressure sensor device. A maximal vertical distance between a part of the bond wire and the semiconductor die is larger than a minimal vertical distance between the semiconductor die and a surface of a gel covering the semiconductor die.

Abstract: Examples provide for an apparatus, method, and computer program for comparing the output of sensor cells in an arrangement of sensor cells in an area A, including a set of at least two measurement units. A measurement unit includes at least two sensor cells, wherein at least one sensor cell of at least one measurement unit includes a sensitive sensor cell, which is sensitive with respect to a measured quantity. The sensor cells are intermixed with each other. The apparatus further includes means for selecting output signals of sensor cells of the arrangement and means for determining a measured quantity or determining an intact sensor cell by comparing output signals of different measurement units.
