In the manufacture of a substrate with a hydrophobic film used for a reference electrode of an ion sensor or the like, a hydrophobic film is formed on a substrate by irradiating a target consisting of a hydrophobic compound with a neutral atom beam and thereby effecting sputtering. The apparatus for effecting the sputtering comprises a target base disposed in a vacuum chamber, an atom beam gun for irradiating a target on the target base with a neutral beam, a substrate base and a shutter for controlling the passage of sputtered particles. A thin film that is manufactured is suitable for an ion sensor, such as an ISFET or the like or an enzyme sensor.

Apparatus for forming thin film

A reference electrode for generating a reference potential on an ion sensor is disclosed. The reference electrode has a lamination film covering a surface of an electrically conductive substrate and formed by alternately laminating silver halide thin films and hydrophobic resin thin films.

Reference electrode

An electrochromic display composed of a transparent electroconductive membrane, an electrochromic membrane, an ion-exchange membrane and a counter electrode in a laminated structure. The ion-exchange membrane is a bipolar ion-exchange membrane composed of at least one cation-exchange membrane layer having cation-exchange groups and at least one anion-exchange membrane layer containing anion-exchange groups in a laminated structure. The electrochromic display has a superior response speed, contrast and resolving power as well as a long service life.
