ANTI-REFLECTION COATED IMAGE SENSOR AND MANUFACTURING METHOD THEREOF

摘要

An image sensor coated with an anti-reflection material having a microlens provided on a semiconductor substrate, the microlens corresponding to a light receiving device formed in the semiconductor substrate wherein the image sensor includes a first layer coated on a surface of the microlens, and a second layer coated on the first layer, wherein the second layer has a smaller refractive index than the first layer.
