  • Patent number: 9230919
    Abstract: A rigid wave pattern formed on a first side of a substrate in a semiconductor die package. The rigid wave pattern aligns with and overlies the contact fingers formed on the second side of the substrate. The rigid wave pattern includes a first pattern with an etched portion and an unetched portion around the etched portion. When the substrate and dice are encased during the molding process, the rigid wave pattern effectively reduces deformation of and stresses on the dice, therefore substantially alleviating die cracking.

    Abstract: A multi-surface nanoparticle source includes a first end having an inlet configured to receive a flow of gas, a second end comprising an outlet through which nanoparticles exit the nanoparticle source, and two or more targets spaced apart and arranged about an axis extending from the first end to the second end. At least at least one of the targets is hollow, and the inlet is arranged to direct a flow of the gas through the hollow target, between at least two of the targets, or both. The gas impacts the targets, releasing atoms from the target and through the second end. The targets may be arranged lengthwise and concentrically about the axis. In some cases, a multi-surface nanoparticle source includes one or more magnets. Nanoparticles formed with a multi-surface nanoparticle deposition system may be homogeneous or have a core-shell structure.

  • Patent number: 9209159
    Abstract: A strengthened semiconductor die substrate and package are disclosed. The substrate may include contact fingers formed with nonlinear edges. Providing a nonlinear contour to the contact finger edges reduces the mechanical stress exerted on the semiconductor die which would otherwise occur with straight edges to the contact fingers. The substrate may additionally or alternatively include plating traces extending at an angle from the contact fingers. Extending at an angle, at least the ends of the plating traces at the edge of the substrate are covered beneath a lid in which the semiconductor package is encased. Thus, when in use with a host device, contact between the ends of the plating traces beneath the lid and contact pins of the host device is avoided.
