主权项

1. A packaged optoelectronic chip comprising:
a die including at least one of a radiation emitter and a radiation receiver, the die including a first surface, a second opposed surface, edge surfaces extending in a direction away from the first surface, and bond pads exposed at the first surface of the die; a transparent packaging layer overlying one of the first and second surfaces of the die, the transparent packaging layer having an inner surface facing the die, an opposed outer surface, and a plurality of edges, the plurality of edges defining a step and each of the plurality of edges having surfaces facing an exterior of the chip package, at least some of the plurality of edges extending at least partially between the inner and outer surfaces of the transparent packaging layer, the at least some of the plurality of edges including a first edge surface bounding an exterior perimeter of the inner surface and a second edge surface bounding an exterior perimeter of the outer surface; and an opaque layer covering a portion of the transparent packaging layer adjacent at least one of the plurality of edges of the transparent packaging layer.
