A system of measuring pH of a solution having a calibration device to counteract time-drift effect. The calibration device of the system adjusts a compensation voltage to zero a measuring voltage of a first sensor and only respond to time-drift voltage of the first sensor. The calibration device has a differential operation amplifier receiving measuring voltages from the first sensor and a second sensor of the system to eliminate the time-drift voltages of the first and second sensors, thereby achieving calibration of the time-drift effects.

An a-C:H ISFET device and manufacturing method thereof. The present invention prepares a-C:H as the detection membrane of an ISFET by plasma enhanced low pressure chemical vapor deposition (PE-LPCVD) to obtain an a-C:H ISFET. The present invention also measures the current-voltage curve for different pH and temperatures by a current measuring system. The temperature parameter of the a-C:H ISFET is calculated according to the relationship between the current-voltage curve and temperature. In addition, the drift rates of the a-C:H ISFET for different pH and hysteresis width of the a-C:H ISFET for different pH loops are calculated by a constant voltage/current circuit and a voltage-time recorder to measure the gate voltage of the a-C:H ISFET.
摘要:
A xerographic photoreceptor primarily formed by amorphous silicon material is disclosed, wherein the xerographic photoreccptor is a photosensitive drum used in copying and manufactured by the plasma enhanced low pressure chemical vapor deposition system. Such a drum has a higher resolution, and a longer lifetime. In this structure, an Al2O3 oxidization layer is grown on an aluminum substrate. Then a n type hydrogenated amorphous silicon blocking layer is grown on the aluminum substrate with Al2O3 oxidization layer. Then an intrinsic hydrogenated amorphous silicon charge generating transmission layer is grown on the n type hydrogenated amorphous silicon blocking layer. Finally a hydrogenated amorphous carbon surface protecting layer is grown on the intrinsic hydrogenated amorphous silicon charge generation transport layer for forming a xerographic photoreceptor with a multiple layer structure. Not only the manufacturing process is simple, but also a lager area is achieved in preparing a film manufacture and thus, the cost will be reduced.
