Title: Thin-type junction type chemical sensor and sample detection method using it
Inventor: USHIO KAJIRO
IPC: G01N21/75
Filed: 1991-09-25
Abstract: PURPOSE:To enable a sample to be detected with an improved sensitivity by providing a means for irradiating light to a junction interface of a sensor where the junction interface between a first thin-film member and a second thin-film member is exposed. CONSTITUTION:A lower electrode 4 is formed by vacuum depositing Au which is approximately 0.01mum thick on the entire surface of a rectangular glass substrate 5 which is for example 15mmX15mm. Similarly, Cuo which is a P-type semiconductor is deposited with a thickness of approximately 0.5mum on an entire surface for forming a second thin-film member 2 and ZnO which is an n-type semiconductor is deposited with a thickness of approximately 0.5mum for forming a first thin-film member 1. Finally, Al is deposited with a thickness of approximately 0.01mum thus forming an upper electrode 3. A target chemical sensor is obtained by patterning ZnO and Al in a same shape by the lift-off method. When moisture is detected while irradiating 400nm light to this element, light current increases greatly above a certain application voltage, thus enabling sensitivity to be increased.
