Abstract:
Systems, methods, and other embodiments associated with an etched hybrid die package are described. According to one embodiment, a method includes electrically connecting a semiconductor die to at least one of a plurality of primary leads and at least one feature. The method includes applying an encapsulant material to a lead-frame that includes the plurality of primary leads to form a package body. Portions of the primary leads protrude from the package body and portions of the at least one feature are exposed within the package body. The method includes chemically etching a die pad exposed within the package body to form and electrically isolate the at least one feature from the die pad. Chemically etching includes fully etching the at least one feature from the die pad.
