Title:
SEMICONDUCTOR DEVICE, AND POTENTIAL MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/101075
Kind Code:
A1
Abstract:
The present invention relates to: a semiconductor device which enables electrostatic discharge damage to be inhibited in an electrode formation process when providing electrodes and an amplification unit to the same substrate; and a potential measurement device. A cathode is connected to a first part of an amplification transistor for amplifying a signal read by a read electrode which is in contact with a liquid that introduces a sample, and which reads the potential, and a diode for grounding an anode is provided. As a result of this configuration, a negative charge generated between electrodes and the amplification transistor in an electrode formation process is bypassed from the diode and discharged in the ground direction, and thus electrostatic discharge damage is inhibited. The present invention is applicable to bioelectric potential measurement devices.
