Title:
IMAGE SENSOR AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2018078264
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide: an image sensor which enables the rise in the light sensitivity of each pixel; and a method for manufacturing such an image sensor.SOLUTION: The image sensor comprises at least a photoelectric conversion element 3 and a micro lens 1 which are stacked on a silicon wafer 4 in this order, in which pixels of respective colors, i.e. green, blue and red are formed. Supposing that the height of the micro lens 1 over the green pixel is 100%, the height of the micro lens 1 over the blue pixel is in a range of 105% to 150%, and the height of the micro lens 1 over the red pixel is in a range of 95% to 70%.SELECTED DRAWING: Figure 1
