Abstract:
1. A sensor chip of an electrical signal detection type, connected to an inspection device body, the sensor chip comprising: a semiconductor sensing device including at least a first transistor and a second transistor, the first transistor allowing an electric charge to flow as a signal and the second transistor is connected to the first transistor with a connecting portion; an inter-element separation film, wherein the first transistor and the second transistor are separated by the inter-element separation film; a connecting member to electrically connect to the inspection device body, wherein the sensor chip is detachable with respect to the inspection device; a sensor portion in which a receptor is disposed; a substrate channel disposed on the sensor chip, the substrate channel including a material introducing port and an opening; and a sealing member disposed on the substrate channel so to seal the opening of the substrate channel, wherein the sensor portion defines an opening through which the receptor is introduced, the receptor is an agent that reacts physically and through contact with a material to be sensed, the first transistor is an ion sensitive field effect transistor, the material introducing port and the opening of the substrate channel are connected via a channel, and the opening of the substrate channel is positioned above the opening through which the receptor is introduced.
