  • Patent number: 7408248
    Abstract: A lead frame for semiconductor device is provided with an inner lead part and an outer lead part. A composite plating layer is provided on the entire plane of a base material constituting the lead frame or at least on the outer lead part. The composite plating layer includes a base layer composed of an Ni-based plating layer formed on the entire plane of the base material constituting the lead frame or at least on the outer lead part, a Pd or Pd alloy plating layer formed on an upper plane of the base layer with a thickness of 0.005-0.01 ?m, and an Au plating layer formed on an upper plane of the Pd or Pd alloy plating layer with a thickness of 0.02-0.1 ?m. The lead frame for semiconductor device has a Pd-PPF structure.

  • Publication number: 20070272441
    Abstract: A highly reliable plated lead finishing structure for a semiconductor part using a Pd film or a Pd alloy film, instead of a traditional solder plating material, as a brazing metal, without causing a problem of short-circuits between terminals due to whiskers, is provided. In the plated lead finishing structure of the invention, when a plated film having a thickness of not larger than 0.3 ?m is formed using Pd or a Pd alloy (26), instead of a conventional solder-plating material as a brazing metal, on the surfaces of the external connection terminals (10, 12) of a semiconductor part using copper or a copper alloy-based material, the film is plated without interposing any underlying layer or any intermediate metal layer between the material and the Pd— or Pd alloy-plated layer. In some cases, Au or an Au alloy (28) is further plated and has a thickness of not larger than 0.1 ?m on the plated film.

  • Patent number: 7190057
    Abstract: A packaging component used for constituting a package mounting a semiconductor element, and a semiconductor package using the packaging component. The packaging component has on at least a portion of the surface thereof a covered surface which is sealed with an insulating resin or on which an adhesive layer is applied, and the packaging component comprises a conductor substrate and an electrically conducting layer partly or entirely covering the surface thereof, and the electrically conducting layer comprises a rough-surface plated layer having a roughened surface profile on the covered surface. The packaging component includes, for example, a lead frame and a heat-radiating or heat-dissipating plate.

  • Publication number: 20060125073
    Abstract: Lead frames of a Pd-PPF structure for use in a semiconductor device comprising inner leads and outer leads, wherein a whole surface of the substrate constituting the lead frame or at least the outer leads has a composite plated layer, and the composite plated layer comprises an underlayer consisting of an Ni-based plating layer deposited on the whole surface of the substrate constituting the lead frame or on at least the outer leads, a Pd— or Pd alloy-plating layer deposited at a thickness of 0.005 to 0.01 ?m on an upper surface of the underlayer, and an Au-plating layer deposited at a thickness of 0.02 to 0.1 ?m on an upper surface of the Pd— or Pd alloy-plating layer. When a semiconductor device is mounted on a packaging substrate by using a lead-free Sn—Zn-based solder or any other lead-free solder, the wettability between the lead frame and the lead-free Sn—Zn-based solder or any other lead-free solder is improved to thereby improve the packaging property of the semiconductor device.
