ELECTRONIC IMAGING DEVICE

摘要

An electronic imaging device includes a base layer containing electrical functional circuitry, the base layer having a first side for interconnection of the circuitry and a second side which serves as a photo-detection side. The second side has exposed photosensitive electrical elements arranged in the base layer. Spacers of a predetermined height are provided adjacent to said second side. The spacers can advantageously be used for gaining control over the tolerance of a desired distance between a lens of a lens system and said photo-detection side. Thus, individual focusing of the lens system of each imager device after completion of production is no longer needed. Moreover, an air gap that improves the performance of the micro-lenses may be formed.
