摘要： A method of plating a semiconductor wafer while maintaining a uniform thickness of the plated film, preventing the precipitation on the back surface of the wafer and preventing the contamination in the subsequent steps. In directly forming connection terminals on the aluminum electrodes on the semiconductor wafer, the non-electrolytic plating is effected in a state where the back surface of the wafer is covered with an insulator. The insulator is preferably a glass substrate which is a part constituting the product. A semiconductor type sensor exhibits improved corrosion resistance against a corrosive medium. The semiconductor type sensor has, in a semiconductor substrate, a structural portion for detecting the physical quantity or the chemical component of a corrosive medium and an electric quantity conversion element, and has pads which are the output terminals for sending the detected electric signals to an external unit, wherein the pads are protected by a precious metal.

摘要： A semiconductor pressure sensor includes a semiconductor substrate having a diaphragm for receiving pressure and a bridge circuit for detecting a distortion of the diaphragm corresponding to the pressure. The bridge circuit includes a pair of first gauge resistors and a pair of second gauge resistors. The first gauge resistors are disposed on a center of the diaphragm, and the second gauge resistors are disposed on a periphery of the diaphragm. Each first gauge resistor has a first resistance, which is larger than a second resistance of each second gauge resistor. The TNO property of the sensor is improved, so that the sensor has high detection accuracy.

摘要： A pressure sensor includes: a casing; a sensor chip with a gauge resistor; a boss disposed on the gauge resistor; a metallic diaphragm capable of distorting in accordance with a pressure; and a load transmission member disposed between the metallic diaphragm and the boss. The casing accommodates the sensor chip, the boss and the load transmission member. The casing is covered with the metallic diaphragm. The pressure applied to the diaphragm is detected such that the load corresponding to the pressure is applied to the gauge resistor through the metallic diaphragm, the load transmission member and the boss so that the pressure is measured on the basis of a resistance change of the gauge resistor. The gauge resistor is larger than the boss.

摘要： A reference voltage generating circuit is constituted by resistors RE and RF each having a resistance not influenced by an application of pressure. The reference voltage generating circuit is connected between one and the other ends of a bridge circuit. A failure judgement of the bridge circuit is performed based on a comparison of a voltage difference VBC between two midpoints B and C of the bridge circuit and voltage differences VCE and VBE between a reference voltage level of the reference voltage generating circuit and the voltage levels of two midpoints B and C.
