Abstract

PURPOSE: To measure low-noise, low-concentration liquid to be inspected by composing the enzyme sensor of a conductive layer produced at the ion sensing part of a junction type FET and an enzyme fixing layer which covers the conductive layer.
CONSTITUTION: The enzyme sensor is constituted by forming a p-n junction type FET on a p-type silicon substrate 1 and providing iridium oxide forming the ion sensing film 2 having the enzyme fixing film 3 on an insulator 4 at a slight distance from the p-n junction type FET. The p-n junction type FET has a drain part 6, a source part 7 and a gate part 5, which is connected to the ion sensing film 2. The enzyme fixing film 3 of 300W1,000Å in thickness is provided on the ion sensing film 2 at a distance from the gate part 5. This enzyme fixing film 3 has enzyme and also operates to support the enzyme on the ion sensing film 2.
