Abstract
The present invention provides a method of forming micro lenses over a base structure of a solid state image pick-up device. The method comprises the steps of: forming a light-transmitting material layer on the base structure; and pushing a die having a die pattern against the light-transmitting material layer to transfer the die pattern of the die to the light-transmitting material layer, thereby forming micro lens patterns over the base structure.
