ABSTRACT:
The electronic device is formed in a die including a body of semiconductor material having a first face covered by a covering structure and a second face. An integral thermal spreader of metal is grown galvanically on the second face during the manufacture of a wafer, prior to cutting into dice. The covering structure comprises a passivation region and a protective region of opaque polyimide; the protective region and the passivation region are opened above the contact pads for the passage of leads.
