    Abstract: In QFN packages for vehicles which are required to have high reliability, the side surface of leads is mostly covered with lead-to-lead resin protrusions, which prevent smooth formation of solder fillets during reflow mounting. When the lead-to-lead protrusions are mechanically removed using a punching die, there is a high possibility of causing cracks of the main body of the package or terminal deformation. When a spacing is provided between the punching die and the main body of the package in order to avoid such damages, a resin residue is produced to hinder complete removal of this lead-to-lead resin protrusion. The present invention provides a method for manufacturing semiconductor device of a QFN type package using multiple leadframes having a dam bar for tying external end portions of a plurality of leads.

  • Publication number: 20110281403
    Abstract: The present invention describes two methods (200, 400) for encapsulating semiconductor dies. Both methods (200, 400) involve attaching an encapsulation spacer (102, 302, 302a, 302b) having one or more apertures (104, 304) on an associated substrate (150) so that a group of chips (160) is located within the aperture (104, 304). The first method (200) involves dispensing encapsulant (103) directly into an aperture. The second method (400) involves attaching an encapsulant delivery layer (350, 351) onto the encapsulation spacer and discharging encapsulant into an aperture via a recessed gate (308).

  • Publication number: 20110281398
    Abstract: Embodiments of the present invention include a method of packaging semiconductor devices. The method comprises the steps of molding a surface of a wafer, sawing the wafer into individual devices, attaching the individual semiconductor device to an adhesive surface, molding the exposed surface, and sawing the wafer into individual semiconductor devices. The step of molding forms a continuous molded layer. The step of sawing results in each individual semiconductor having a molded layer. This molded layer corresponds to a portion of the continuous molded layer. The step of attaching includes attaching the molded layer of the individual semiconductor devices to the adhesive surface. The step of molding the exposed area includes molding an exposed area above the adhesive surface. This forms a solid expanse of material. The step of sawing the wafer into individual semiconductor devices includes sawing the solid expanse of material.

  • Publication number: 20110221059
    Abstract: A QFN package includes a chip-mounting base; electrically connecting pads disposed around the periphery of the chip-mounting base, the bottom surfaces of the chip-mounting base and the electrically connecting pads being covered by a copper layer; a chip mounted on the top surface of the chip-mounting base; bonding wires electrically connecting to the chip and the electrically connecting pads; an encapsulant encapsulating the chip-mounting base, the electrically connecting pads, the chip and the bonding wires while exposing the copper layer; and a dielectric layer formed on the bottom surfaces of the encapsulant and the copper layer and having a plurality of openings exposing a portion of the copper layer. The copper layer has good bonding with the dielectric layer that helps to prevent solder material in a reflow process from permeating into the interface between the chip-mounting base, the electrically connecting pads and the dielectric layer, thereby avoiding solder extrusion and enhancing product yield.

  • Patent number: 8017445
    Abstract: A method and packaging for semiconductor devices and integrated circuits is disclosed that eliminates warpage stress on packages caused by coefficient of thermal expansion (CTE) mismatch between the device, lead frame or die paddle and a molding compound. Generally, the method includes steps of: (i) mounting the die on which the device is fabricated to a die paddle of a leadframe; and (ii) encapsulating the die on the die paddle and at least a portion of the leadframe in a molding compound, wherein a difference between a first volume of molding compound above a plane of the leadframe and a second volume of molding compound below the plane of the leadframe is sufficiently reduced to substantially eliminate warpage of the finished package due to mismatch of CTEs of the device, lead frame and packaging compound. The die paddle may be etched or reduced to facilitate molding compound flowing under the plane of the leadframe. Other embodiments are also disclosed.
