Solidstate image sensor

Abstract

Abstract PURPOSE:To increase the amount of photoelectric conversion and to improve the sensitivity, by using a means collecting light to the photoelectric section. CONSTITUTION:A convex lens 11 collecting light to a photoelectric conversion section, preliminarily processed in the convex shape to match with each cell size so as to focus the light to an effective photoelectric conversion section, that is, an N type diffusion layer 7, by substances capable of transmission of light, e.g., glass, plastic and various oxides, and these produced layers are adhered on the pellet. Thus, the increase in the sensitivity is realize without increasing the cell area in the application of the collecting conex lens.
