MULTI-COMPONENT MODULES (MCMs) INCLUDING CONFIGURABLE ELECTRO-MAGNETIC ISOLATION (EMI) SHIELD STRUCTURES, AND RELATED METHODS

Abstract:

Multi-component modules (MCMs) including configurable electromagnetic interference (EMI) shield structures, and related methods are disclosed. An EMI shield enclosing an IC or another electrical component in an MCM can protect other components within the MCM from EMI generated by the enclosed component. The EMI shield also protects the enclosed component from the EMI generated by other electrical components. An EMI shield with side-wall structures, in which vertical conductors supported by a wall medium electrically couple a lid of the EMI shield to a ground layer in a substrate, provides configurable EMI protection in an MCM. The EMI shield may also be employed to increase heat dissipation. The side-wall structures of the EMI shield are disposed on one or more sides of an electrical component and are configurable to provide a desired level of EMI isolation.
