Abstract
PURPOSE: To improve the S/N of the bubble detection output, by providing the compensating resistance on the chip to give a compensation to the difference of resistance value between the main detector and the dummy detector.
CONSTITUTION: The main detector 19, the dummy detector 20 and the compensating resistance 21 are provided on the chip. The resistance 21 is obtained by evaporating the material same as the detectors with variation of the resistance value in a range of about several Ω to several tens of Ω onto plural units of chips. Such resistance is connected so as to secure a coincidence of resistance between the both detectors mentioned above after measuring the resistance of both detetors. In such a way, the S/N can be improved for the bubble detection output, thus increasing the chip yield.
