  • Patent number: 11289409
    Abstract: 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.

  • Patent number: 9190296
    Abstract: A semiconductor package without a chip carrier formed thereon and a fabrication method thereof. A metallic carrier is half-etched to form a plurality of grooves and metal studs corresponding to the grooves. The grooves are filled with a first encapsulant and a plurality of bonding pads are formed on the metal studs. The first encapsulant is bonded with the metal studs directly. Each of the bonding pads and one of the metal studs corresponding to the bonding pad form a T-shaped structure. Therefore, bonding force between the metal studs and the first encapsulant is enhanced such that delamination is avoided. Die mounting, wire-bonding and molding processes are performed subsequently. Since the half-etched grooves are filled with the first encapsulant, the drawback of having pliable metallic carrier that makes transportation difficult to carry out as encountered in prior techniques is overcome, and the manufacturing cost is educed by not requiring the use of costly metals as an etching resist layer.

  • Patent number: 6509636
    Abstract: A photosensitive semiconductor package with a lid is proposed, in which a chip carrier is formed with an encapsulant thereon, and the encapsulant is formed with a cavity for exposing a semiconductor chip mounted on the chip carrier. A top of the encapsulant is structured with a groove and at least a beveled portion that descends toward the groove and is associated with the groove. When a lid is attached onto the encapsulant by using an adhesive, the groove can temporarily retain excess adhesive with its flow being directed toward the groove by the beveled portion, so that undersirable adhesive loss and adhesive flash can both be prevented from occurrence, allowing the appearance of the semiconductor package to be well maintained.
