Title: Production of ion-sensitive film for ion-sensitive fet
Inventor: HIRAOKA SUSUMU
IPC: G01N27/414
Filed: 1993-03-19
Abstract: PURPOSE:To form a high sensitivity ion-sensitive film excellent in adhesion by depositing an ionophore compound having a deposit polymerization function group at the gate part of a FET thereby forming a polymer film. CONSTITUTION:An ionophore compound, e.g. a crown ether-based compound, having a cyclic polyether part to which a deposit polymerization function group is introduced to produce a monomer being employed as a material for forming an ion-sensitive film. A hydrophobic polymer layer having high crystallinity is previously formed by 0.2-0.5mum thick at the gate part of a FET and a hydrophilic polymer layer is formed thereon by 0.1-0.3mum thick through deposit polymerization using a monomer having a hydrophilic group. Since the ionophore is chemically bonded to the film, elution thereof to the outside of the ion- sensitive FET is prevented during use thus sustaining the ion-sensitive function for a long time. Furthermore, thermal damage onto the FET element can be suppressed because the film can be deposited at a temperature as low as 100 deg.C.
