Patent ID: 8778740

Claim:
A method of fabricating a leadframe for a semiconductor package comprising; forming a first mask layer on a surface of the leadframe where a first die pad is to be located; performing a first partial etch of the leadframe around the first mask layer to define a level of a bottom surface of a second die pad; forming a second mask layer where the bottom surface of the second die pad is to be located; performing a second partial etch of the leadframe around the second mask layer to define a level of an embedded bottom surface of each of a plurality of contacts; forming a third mask where each of the plurality of contacts is to be located, the third mask extending between at least one of the contacts and the second die pad; and performing a third etch of the leadframe to separate each of the contacts from each other and from the first die pad and to separate each of the contacts except the at least one contact from the second die pad.
