| abstract | BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure sensor, wherein a ring-shaped base and a high hardness joined by a joint formed by overlapping a circular edge portion on one side corresponding to the other side to which pressure is applied are formed. A diaphragm made of an insulating material having an elastic force, a plurality of resistors each having a width and a length in a portion or a center portion adjacent to the base on the diaphragm, the lengths having the same direction, and on the diaphragm A plurality of electrodes formed to form a Wheatstone bridge configuration with the plurality of resistors at a peripheral portion corresponding to the base, and covering the plurality of resistors on the diaphragm and exposing the plurality of electrodes by an opening. It has a protective film formed so that it may be. Therefore, since no capacitance is generated between the base and the first, second, third and fourth resistors, the operating characteristics can be improved, and since the elastic force of the diaphragm is large, the linearity and reproducibility of the resistance value are improved. In addition, hysteresis and creep properties are improved. |
