Semiconductor apparatus and potential measuring apparatus
The present disclosure relates to a semiconductor apparatus and a potential measuring apparatus capable of preventing deterioration in signal characteristics due to parasitic capacitance caused by providing a configuration for realizing an electrode plating process when an electrode and an amplifier are provided on the same substrate. When a power source supplies a potential necessary for plating processing and a breaker reads a signal from liquid, and an amplifier amplifies and outputs the signal, the power source required for the plating processing is blocked with respect to the electrode. This is applicable to the potential measuring apparatus.
