Abstract:
A packaged semiconductor device includes: a substrate; an semiconductor die attached to a top surface of the substrate; a mold body surrounding the semiconductor die; a tiered through mold via (TMV) comprising: a first recess having a recessed surface within the mold body at a first depth, and a second recess from the recessed surface to a second depth that exposes a ground contact area on a bonding area on the top surface of the substrate, wherein the first depth is greater than the second depth; and a metal shielding layer formed on a top surface of the mold body to form a shielded mold body, wherein the metal shielding layer makes direct contact with at least one sidewall of the first recess, with at least a portion of the recessed surface, with at least one sidewall of the second recess, and with the ground contact area.
