A scanning analyzer unit comprises a scanner device, a signal amplifier, an analog/digital converter, a driver device, a controller device, a computing unit, and a RS-232 interface. After chemical, biological, or chemi-enzymatic reaction, a resulting color change of a testing support through reacted multi-chromogens therein is quantified by means of the scanning analyzer unit. Via the sensitivity differences of the multi-chromogens at a fixed wavelength of the scan, multi-analyte concentrations of wide range variations in one sample can be simultaneously assayed.
A semiconductor integrated circuit device according to the present invention includes a diode in a second island region. The anode region of the diode and the dividing region in a first island region having a horizontal PNP transistor are electrically connected to each other; the cathode region of the diode and the collector region of a power NPN transistor are electrically connected to each other. Accordingly, the dividing region in the first island region having a horizontal PNP transistor becomes lower in potential than the dividing regions in the other island regions, so that the inflow of free carriers (electrons) to the horizontal PNP transistor can be prevented.
