Abstract
Ground shielding is achieved by a conductor shield having conductive surfaces that immediately surround individual chips within a multichip module or device, such as a multichip module or device with flip-chip (FC) bumps. Intra-module shielding between individual chips within the multichip module or device is achieved by electromagnetic or radio-signal (RF) isolation provided by the surfaces of the conductor shield immediately surrounding each of the chips. The conductor shield is directly connected to one or more grounded conductor portions of a substrate or interposer to ensure reliable grounding.
