Abstract
Interposer and semiconductor package embodiments provide for the isolation and suppression of electronic noise such as EM emissions in the semiconductor package. The interposer includes shield structures in various embodiments, the shield structures blocking the electrical noise from the noise source, from other electrical signals or devices. The shields include solid structures and some embodiments and decoupling capacitors in other embodiments. The coupling structures includes multiple rows of solder balls included in strips that couple the components and surround and contain the source of electrical noise.
