Light-Guiding Structure, Image Sensor Including The Light-Guiding Structure, And Processor-Based System Including The Image Sensor

摘要

An example embodiment relates to a light-guiding structure. The light-guiding structure may include a bottom surface and a sidewall defined by a first, a second, and a third insulating layer disposed on a semiconductor substrate. The bottom surface may be parallel to a main surface of the semiconductor substrate and may be disposed in the first insulating layer. The sidewall may penetrate the second and third insulating layers to extend to the first insulating layer, and the sidewall may be tapered with respect to the main surface of semiconductor substrate. The light-guiding structure may be included in a image sensor. The image sensor may be included in a processor-based system.
