Abstract

Disclosed herein is an ion-sensitive field-effect transistor (ISFET) (100) having nanostructures (109) for sensing ions and measuring ion concentration in solutions. In general, the base layer (101) at the sensing region of the ISFET (100) is etched to form the nanostructures (109). Each of the nanostructures (109) has a diameter of less than 100nm, and the nanostructures (109) have a distance of less than 100nm from each other. The nanostructures (109) are nanopillars with cylindrical shape, needle-like shape, or a combination thereof. Due to all these particular features, the surface area of the ISFET (100) that is exposed to ions is increased, and therefore the sensitivity and efficiency of the ISFET (100) are improved. Also disclosed herein is a fabrication method thereof.
