摘要： An object of the present invention is to solve problems in that aluminum electrodes, aluminum wires, and I/O terminals are corroded by corrosive gasses when a pressure of a pressure medium containing corrosive matters such as exhaust gas is measured with a semiconductor sensor; and improve not only the corrosion resistance of the sensor chip but also the corrosion resistance of the portion particularly functioning as the pressure receiver.Each of the aluminum electrodes that is likely to be corroded portions is prevented from being corroded by forming a titanium-tungsten layer and gold layer on the aluminum electrode. The connecting wires are prevented from being corroded by corrosive matters by using gold wires. The I/O terminals are also prevented from being corroded by applying gold plating.

摘要： Many holes are formed in an interlayer insulating film and the surface of the interlayer insulating film is covered with a metal film, with its surface undulated by openings or recesses formed to scatter reflection light. The size of the recesses is about the size of contact holes of elements. Hence the recesses are not detectable by an image recognition apparatus. The size of the metal film, however, is set so that it can be detected by the image recognition apparatus.

The pulled-up pads and the power supply pad are electrically connected to a power supply terminal outside the chip via the internal exposed portions, the wires, and a power-supply-connecting external wire. Terminals may be electrically connected together on a package or a mounting substrate.

摘要： This invention provides a low-current consumption type signal amplification circuit, which limits the output voltage to fix a lower-limit (upper-limit) saturation voltage of the amplification circuit at a predetermined lower-limit (upper-limit) limiting voltage. The signal amplification circuit comprises a negative feedback amplification circuit, a lower-limit voltage limiting circuit and an upper-limit voltage limiting circuit. The lower-limit voltage limiting circuit increases a resistance between an output terminal of the negative feedback amplification circuit and a ground terminal when the output voltage of the negative feedback amplification circuit falls below the lower-limit limiting voltage. The upper-limit voltage limiting circuit increases a resistance between the output terminal of the negative feedback amplification circuit and a high-potential side of a power supply when the output voltage of the negative feedback amplification circuit rises above the upper-limit limiting voltage.
