Abstract:
1. A method for forming a first shielding structure on a semiconductor die, wherein the semiconductor die (i) is to be coupled, via a solder bump that emits alpha particles, to a package substrate and (ii) comprises an integrated circuit device, the method comprising: depositing an electrically insulative material on a pad structure of the semiconductor die, wherein the pad structure is electrically coupled to the integrated circuit device; patterning the electrically insulative material to expose the pad structure; depositing a metal on at least a portion of the exposed pad structure to form the first shielding structure, wherein the first shielding structure is configured to shield the integrated circuit device from the alpha particles emitted from the solder bump, and wherein the metal of the first shielding structure is electrically coupled to the pad structure; and depositing the electrically insulative material to encapsulate the first shielding structure within the electrically insulative material.
