Abstract
Official abstract text for this publication.
A gas sensor device includes a first electrode, a second electrode, and a polythiophene film which is formed between the first and second electrodes to be electrically coupled to the first and second electrodes, and to which cuprous bromide is adsorbed.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing a gas sensor device, the method comprising: forming a first electrode and a second electrode on a substrate; forming a polythiophene film on the substrate between the first and second electrodes to be electrically coupled to the first and second electrodes by applying a solution which is obtained by dissolving polythiophene in organic solvent into the substrate and performing a first drying; bringing a cupric bromide into contact with the polythiophene film by contacting the polythiophene film and the cupric bromide; and forming the polythiophene film absorbed the cuprous bromide, the contacting the polythiophene film and the cupric bromide is performed by dropping a solution of the cupric bromide into the polythiophene film, washing the polythiophene film after a specific period of time elapses and performing a second drying. 2. The method of manufacturing a gas sensor device according to claim 1 , wherein the solution is applied into a rectangular shape having a side of a specific length.
