Provided is a detector having a transistor or resistor structure. When an electrode is exposed to a detected solution, such as blood, a variation in current flowing through the detected solution may be greater than a variation in the electrical characteristics of the detector caused by a variation in the physical properties of semiconductor so that it is difficult to detect whether a bio-particle is contained in the detected solution. In order to solve this problem, a detection portion and an electrical measurement portion are separately formed, and the detection portion is processed with the bio-particle and then post-processed. Subsequently, the detection portion and the electrical measurement portion are bonded to each other using, for example, a laminating process, and the detector measures a detection value.

What is claimed is: 1. A detector comprising:a first substrate including a first electrode, a dielectric layer enclosing top and lateral surfaces of the first electrode, and second and third electrodes disposed apart from each other on a portion of a top surface of the dielectric layer; anda second substrate including a frame substrate, and a reactant layer which is disposed on the frame substrate and reacts with a specific functional group,wherein when the reactant layer contacts a fluid to be measured, the first substrate is closely bonded to the second substrate so that the detector measures electrical characteristics between the second and third electrodes.
