Classification: CPC H | IPC H

Claim 8:
9. A digital image sensor package, comprising:
a printed circuit board;
an image sensor substrate stacked on the printed circuit board and including photodiodes; and
a transparent covering associated with the image sensor substrate and having a bottom surface, a top surface opposite the bottom surface, and a sidewall delimiting a perimeter edge of the transparent covering, wherein the transparent covering is monolithic and overlies all of the photodiodes of the image sensor substrate, wherein a surface area of the top surface of the image sensor substrate is greater than a surface area of the bottom surface of the transparent covering;
wherein the sidewall and the top surface of the transparent covering form a first angle, and the sidewall and the bottom surface of the transparent covering form a second angle different than the first angle; and
wherein the first and second angles are such that light that enters the transparent covering on a first trajectory that results in the light impinging upon the sidewall being reflected on a second trajectory that avoids the image sensor substrate.
