Abstract:
1. An optoelectronic package comprising: a substrate; a cover element bonded onto the substrate, the cover element defining a cavity for accommodating semiconductor chips and optoelectronic components; wherein: the cover element comprises a first adhesive bonding area configured for receiving a first adhesive and being bonded with a predetermined region of the substrate by the first adhesive; and the engagement of the cover element and the substrate defines a second adhesive bonding area, the second adhesive bonding area being configured for receiving a second adhesive and confining the second adhesive within a localized area; wherein the cover element comprises two thinned-down recess regions formed at two opposite sides of the cover element respectively, the engagement of the two thinned-down recess regions and the substrate defining the second adhesive bonding area; the second adhesive bonding area comprises a floor defined by the substrate and side walls defined by the two thinned-down recess regions; and wherein a through hole is formed within each of the thinned-down recess regions; and wherein the second adhesive fills in the through hole to further bond the substrate and cover element.
