Abstract: The Application describes a substrate design for a MEMS transducer package. The substrate is defined by a conductive layer which forms the upper and lower surfaces of the substrate. The substrate is also provided with a conductive portion which is electrically isolated from the rest of the conductive layer. The conductive portion is supported between a first plane defined by the upper surface of the substrate and a second plane defined by the lower surface of the substrate by an electrically insulating moulding substance.
