Abstract
Disclosed is a method for forming an image sensor device. First, a lens is provided, and a first sacrificial element is then formed on the lens. Subsequently, an electromagnetic interference layer is formed on the lens and the first sacrificial element, and the first sacrificial element and the electromagnetic interference layer thereon are removed to form an electromagnetic interference pattern having an opening exposing a selected portion of the lens. A second sacrificial element is formed in the opening to cover a center region of the selected portion of the lens, while a peripheral region of the selected portion of the lens remains exposed. Next, a light-shielding layer is formed on the electromagnetic interference pattern, the second sacrificial element, and the peripheral region of the selected portion of the lens. Thereafter, the second sacrificial element and the light-shielding pattern thereon are removed to expose the center region of the selected portion of the lens as a light transmitting region.
