Title:
PRODUCTION OF ION-SENSITIVE FILM
Document Type and Number:
Japanese Patent JPH06273377
Kind Code:
A
Abstract:

PURPOSE: To obtain a highly durable ion-sensitive film exhibiting highly sensitive ion selectivity in which adhesion between a dielectric gate film and a support is enhanced along with the coupling between an ionophore compound and a base film.

CONSTITUTION: In the method for producing an ion-sensitive film, to a polymeric film formed through deposition polymerization, an ionophore compound having a function group reactive therewith is imparted and the compound is bonded chemically thereto. This method allows formation of an ion concentration sensor comprising an ion-sensitive FET and exhibiting highly accurate sensor function for a long term.
