Samsung Electronics Co., Ltd. Develops Image Sensor and Fabrication Method

Strategic Insights -

Samsung Electronics Co., Ltd. has filed a patent for an image sensor and method of fabricating the same, which has been published online. According to the inventors, Jin-Ho Kim and Young-Hoon Park, the inventive concept relates to image sensors and methods of fabricating the same, including backside illuminated image sensors, CMOS image sensors, and methods of fabricating the same. The inventors claim that their image sensor is more sensitive and less costly to manufacture compared to conventional CCD image sensors.

Key Takeaways:

  • The inventive concept relates to image sensors and methods of fabricating the same, including backside illuminated image sensors and CMOS image sensors.
  • The image sensor includes a substrate with a front side and a back side, an insulating structure on the front side comprising circuits, contact holes extending through the substrate to the circuits, and conductive pads on the back side of the substrate electrically connected to the circuits.
  • The image sensor provides improved sensitivity and reduced crosstalk due to its design, which eliminates the need for metal wiring layers and interlayer insulating layers on the front side of the substrate.
  • The method of fabricating the image sensor involves polishing the back side of the substrate to create a light receiving region and a circuit region.
  • The inventors have proposed several aspects of the inventive concept, each providing a unique solution to the problems of conventional image sensors.
