Crack suppression structure for HV isolation component

Abstract:

An integrated circuit (IC) includes a substrate having functional circuitry for realizing at least one circuit function configured together with at least one high voltage isolation component including a top metal feature above the substrate. A crack suppressing dielectric structure including at least a crack resistant dielectric layer is on at least a top of the top metal feature. At least one dielectric passivation overcoat (PO) layer is on an outer portion of the top metal feature.
