An amplifier is formed on the main surface of a first semiconductor substrate by a diffusion process, and its surface is covered with an insulating film. An electrode is vapor-deposited on the surface of the amplifier and electrically connected to the amplifier through a through hole formed in the insulating film. For forming a diaphragm, the surface of a second semiconductor substrate disposed facing the electrode to form a capacitor, which is opposite to the surface of the second semiconductor substrate facing the electrode, is partially etched away to form a depression.

摘要: Four semiconductor strain gauges constitute a bridge circuit. This bridge circuit and a sensitivity temperature compensation circuit are connected in series, and a constant voltage is applied to the series circuit. The sensitivity temperature compensation circuit varies a voltage across the bridge circuit, depending upon temperatures. The constant voltage is divided to produce a predetermined voltage. The predetermined voltage is selected to be equal to the voltage of one output side node of the bridge circuit at the time when the semiconductor strain gauges are unstrained and at a predetermined temperature. The point of this voltage and the output side node are connected through a resistor so as to perform zero-point temperature compensation.

摘要: A semiconductor strain gauge is arranged as a bridge having four piezoresistive elements which each include a low impurity concentration diffused portion and a heavily-doped diffused portion. The resistance values of the two low impurity concentration diffused portions opposite each other in the bridge are greater than the resistance values of the other two lower impurity concentration portions. The resistances of the heavily-doped diffused portion are selected so that the resistance of the piezoresistive elements are equal. However, by virtue of the fact that the resistance temperature coefficient of the low impurity portions are greater than the resistance temperature coefficients of the high impurity portions, the overall resistance temperature coefficients of the bridge arms will be different. This permits the zero-point voltage of the bridge to always increase with an increase in temperature.
摘要翻译: 半导体应变仪布置为具有四个压阻元件的桥,每个压阻元件包括低杂质浓度扩散部分和重掺杂扩散部分。 在桥中彼此相对的两个低杂质浓度扩散部分的电阻值大于其它两个较低杂质浓度部分的电阻值。 选择重掺杂扩散部分的电阻,使得压阻元件的电阻相等。 然而,由于低杂质部分的电阻温度系数大于高杂质部分的电阻温度系数,所以桥臂的整体电阻温度系数将不同。 这允许桥接器的零点电压总是随着温度的升高而增加。
