PROBLEM TO BE SOLVED: To provide an improved process for manufacturing a microelectromechanical component, and to provide the microelectromechanical component capable of being adaptably used for small size microelectromechanical sensor solution.SOLUTION: The microelectromechanical component includes: a microelectromechanical chip part 46 sealed by a cover part 24; and an electronic circuit part 64 suitably joined with the electromechanical chip part 46, and the cover part 24 is penetrated by a conductive structure on which an electric connection part is provided. At least one of widths of the microelectromechanical chip part 46 is greater than a width of the electronic circuit part 64. The electronic circuit part 64 is joined with the microelectromechanical chip part 46 by a first joint member formed on a surface of the electronic circuit part 64. Further, a bump 69 being a second joint member for external connection is formed on a surface of the microelectromechanical chip part 46 being adjacent to the electronic circuit part 64. A height of the bump is greater than or equal to the total height of the electronic circuit 64 and the first joint member.
Abstract:
PROBLEM TO BE SOLVED: To provide a pressure sensor device capable of reducing influence of impact acceleration and assuring reliability of a bonding wire, and a method of manufacturing the same.SOLUTION: The pressure sensor device 10 includes a guide member 11 having a cylindrical portion 11b disposed so as to be opposed to a sensing portion 17a: thickness of a protective member 12 being formed thinner in portions having the cylindrical portion 11b than in portions having the cylindrical portion 11b. In this structure, influence of impact acceleration can be reduced, and false detection of the sensor chip 17 can be eliminated (or greatly reduced) because thickness of the protective member 12 on the sensor chip 17 is formed thin. Furthermore, the bonding wire 13 is wholly covered with the protective member 12. Thus a malfunction concerning exposure of the bonding wire 13 can be prevented to assure reliability.
