PRESSURE SENSOR
Document Type and Number:
Japanese Patent JP3209120
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a pressure sensor which can be downsized.
SOLUTION: A package body 1 having a recess 1a and a pressure introduction hole 1b formed on a bottom of the recess 1a is formed by using mold interconnection device(MID) molded substrate technology, and an electrode 1d is formed from a side wall upper face of the recess 1a toward an outer peripheral face of the package body 1 and toward a rear face of the package body 1. Then a sensor chip 3 is bonded to the bottom of the recess 1a via a glass base 4, and after an electrode 3b and the electrode 1d are wire-bonded via a wire 5, silicon resin 6 is applied on a surface of the sensor chip 3. Further a box-shaped metallic lid 7 comprising a barrier 7a is formed at an outer peripheral end, and the package body 1 and the metallic lid 7 are joined with each other so that a part formed with the recess 1a is covered by the lid 7, thereby manufacturing a pressure sensor.
