Abstract
The present disclosure relates to a semiconductor apparatus and a potential measuring apparatus capable of preventing electrostatic breakdown in an electrode formation process when an electrode and an amplifier are provided on a same substrate. A diode is provided of which a cathode is connected to a previous stage of an amplifying transistor for amplifying a signal read by a read electrode for reading a potential having contact with liquid in which a specimen is input and an anode is grounded. With such a configuration, by bypassing a negative charge generated between the electrode and the amplifying transistor in the electrode formation process from the diode and discharging the negative charge toward ground so as to prevent electrostatic breakdown. This is applicable to a bioelectric potential measuring apparatus.
