ABSTRACT:
An electrically insulative conformal coating is applied at least to the active (front) side and one or more sidewalls of the die during wafer processing. Also, a die has an electrically insulative conformal coating applied to at least the active (front) side and sidewalls. Also, assemblies include a stack of such die, electrically interconnected die-to-die; and assemblies include such a die or a stack of such die, electrically interconnected to underlying circuitry (for example in a substrate or a circuit board).
