IMAGE SENSOR AND METHOD OF FORMING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17738031 titled 'IMAGE SENSOR AND METHOD OF FORMING THE SAME

Simplified Explanation

The abstract describes an image sensor and a method of forming it.

  • The image sensor includes a first substrate with two surfaces.
  • There are multiple photodetectors placed in the first substrate.
  • On the second surface of the first substrate, there are multiple color filters corresponding to the photodetectors.
  • The color filters are made up of PIN diodes.
  • The PIN diodes are designed to absorb light of different wavelength ranges by applying different bias voltages.


Original Abstract Submitted

Provided is an image sensor and a method of forming the same. The image sensor includes a first substrate having a first surface and a second surface opposite to each other; a plurality of photodetectors, disposed in the first substrate; and a plurality of color filters, disposed on the second surface of the first substrate and respectively corresponding to the plurality of photodetectors. The plurality of color filters are composed of a plurality of PIN diodes, and the plurality of PIN diodes are configured to absorb light of different wavelength ranges by applying different bias voltages.
