ABSTRACT:
An image sensor chip is mounted on a printed wiring frame over a substrate, which is plated with a spider web of plated conductors connecting the IC through via holes to the bottom of the substrate as output terminals. After wiring bonding the IC to the plated conductor, the package is sealed. A wall is erected around the image sensor chip and is covered with a transparent glass. A lens may be placed in the middle of the cover for focusing. The structure is amenable to mass production. A large number of printed wiring frames are arranged as a matrix on a common substrate. The frames are sealed column by column or sealed all at once. After sealing, the common substrate are diced into individual packages. The image sensor package may mounted with integrated circuit chips as peripheral circuits. The image sensor chips may be sealed with transparent glue and the integrated circuit chip may be sealed with opaque glue.
