The leadframe-based semiconductor package includes a chip implanted with a plurality of first and second conductive bumps thereon, and a leadframe having a plurality of leads. The first conductive bumps are bonded to the leads to electrically connect the chip to the leadframe. The chip, the first and second conductive bumps, and the leadframe are encapsulated by an encapsulant, with bottom ends of the second conductive bumps and bottom surfaces of the leads being exposed from the encapsulant. This allows the second conductive bumps to provide additional input/output electrical connections for the chip besides the leads.

摘要： A method for fabricating a carrier-free semiconductor package includes: half-etching a metal carrier to form a plurality of recess grooves and a plurality of metal studs each serving in position as a solder pad or a die pad; filing each of the recess grooves with a first encapsulant; forming on the metal studs an antioxidant layer such as a silver plating layer or an organic solderable protection layer; and performing die-bonding, wire-bonding and molding processes respectively to form a second encapsulant encapsulating the chip. The recess grooves are filled with the first encapsulant to enhance the adhesion between the first encapsulant and the metal carrier, thereby solving the conventional problem of having a weak and pliable copper plate and avoiding transportation difficulty. The invention eliminates the use of costly metals as an etching resist layer to reduce fabrication cost, and further allows conductive traces to be flexibly disposed on the metal carrier to enhance electrical connection quality.
