Abstract

See full text

An integrated circuit is divided into a number of sub-circuits by isolation walls in the substrate. A conducting shield overlays every sub-circuit to form a grounded cage with the underlying substrate for trapping electromagnetic radiation generated inside the sub-circuit, and to prevent cross-talk between the sub-circuits.
