Abstract:
Methods of forming semiconductor packages include providing a lead frame having leads and no tie-bars. Tape is attached to the lead frame and one or more semiconductor die are coupled therewith. Electrical contacts of the die are interconnected with the leads using electrical connectors. An encapsulated assembly is formed by at least partially encapsulating the die and electrical connectors. The assembly is singulated to form a semiconductor package. The tape is detached from the package or encapsulated assembly. One or more die attach flags may be attached to the tape and the die may be attached thereto. Semiconductor packages formed using the methods include one or more semiconductor die at least partially encapsulated, pins exposed through the encapsulant, electrical connectors within the encapsulant and electrically interconnecting the pins with electrical contacts of the die, and no tie-bars coupling the die with the pins. Packages may also include die attach flags.
