Abstract
Disclosed is a fluorescent biochip diagnosis device including: an image sensor having a plurality of photo-detectors; and a band-pass filter unit having a plurality of band-pass filters formed on a plurality of the photo-detectors, wherein a plurality of the band-pass filters are implemented by forming a nanostructure pattern in a metal layer. Since the fluorescent biochip diagnosis device has little optical loss due to a short interval between the biochip and the photo-detector, excellent sensitivity can be provided. Also, since signals can be simultaneously measured by combining light beams having a short wavelength used as an illumination depending on a type of a fluorescent protein material, cost of the diagnosis device and a diagnosis time can be reduced.

A fluorescent biochip diagnosis device comprising:
- an image sensor having a plurality of photo-detectors;
- and
- a band-pass filter unit having a plurality of band-pass filters formed on the plurality of the photo-detectors,
- wherein the plurality of the band-pass filters are implemented by forming a nanostructure pattern in a metal layer.
A fluorescent biochip diagnosis device comprising:
- a substrate having a photo-diode region which detects fluorescent light from a biochip, a vertical charge transfer region which is a charge transfer path where electric charges generated by an photoelectric effect in the photodiode region are collected, and an isolation film;
- a gate insulation film and a gate electrode formed on the substrate in this order;
- an interlayer insulation film formed on the substrate having the gate electrode;
- and
- at least one metal layer formed to provide a circuit wiring within the interlayer insulation film,
- wherein at least one band-pass filter having a metal nanostructure is located on an extension line of at least the metal layer.
