発明の名称 (英語) CHEMICAL SENSOR NEW 新技術説明会
発明の概要(英語) The present invention provides a chemical sensor that can be manufactured at a reduced manufacturing cost and that has high detection sensitivity. This chemical sensor is characterized by being provided with a substrate, a semiconductor thin film having a first contact region and a second contact region, an injection electrode, a first MIS structure, a second MIS structure, a transfer electrode, and a capacitor, and moreover is characterized in that: the semiconductor thin film has a response region provided so that the electric potential thereof changes in direct or indirect response to a measured subject; the injection electrode is provided so as to inject an electrical charge into the first contact region; the first MIS structure is provided so as to control the flow, to the response region, of the electrical charge injected into the first contact region by the injection electrode; the second MIS structure is provided so as to control the flow of the electrical charge from the response region to the second contact region; and the transfer electrode is provided so as to allow the electrical charge in the response region to flow through the second contact region to the capacitor.
従来技術、競合技術の概要(英語) BACKGROUND ART
Detecting ions in the solution such as a chemical sensor, ion sensitive transistor has been known (for example, see Patent Document 1). Such a transistor is employed and the pH of the solution can be detected. However, such a pH sensor, a problem that detection sensitivity is low. In addition, the accumulation-type chemical, physical event detection device has been known (for example, see Patent Document 2).
