This abstract first appeared for US patent application 20240258351 titled 'IMAGE SENSOR INCLUDING AUTO-FOCUS PIXELS
Original Abstract Submitted
an image sensor includes a normal pixel, a first auto-focus (af) pixel, and a second af pixel, each of the normal pixel, the first af pixel and the second af pixel including a photodiode. the image sensor further includes a normal microlens disposed on the normal pixel, and a first af microlens disposed on the first af pixel and the second af pixel. the photodiode of the normal pixel, the photodiode of the first af pixel, and the photodiode of the second af pixel are respectively disposed in photo-detecting areas of a semiconductor substrate. a height of the first af microlens in a vertical direction from a top surface of the semiconductor substrate is greater than a height of the normal microlens in the vertical direction from the top surface of the semiconductor substrate.
