Solid-state imaging devices having flat microlenses
A solid-state imaging device having flat microlenses is provided. The solid-state imaging device includes a semiconductor substrate having a plurality of photoelectric conversion elements. The solid-state imaging device further includes a color filter layer disposed above the semiconductor substrate. The solid-state imaging device also includes a microlens having a flat top surface disposed on the color filter layer. The flat top surface of the microlens is directly above the photoelectric conversion element, and the area of the flat top surface of the microlens is equal to the area of the photoelectric conversion element.
