摘要： A leadless package and method for manufacturing silicon based leadless QFN/SON compatible packages are described. In addition the package allows for hermetic sealing of devices while maintaining electrical and optical access. Micro-vias with feed-through metallization through a silicon structure facilitates a surface mount technology-compatible silicon package with bottom SMT pads and top surface device integration. Sloped edges on the SMT side enable solder filleting for post solder inspection. Hermetic seal can be attained for example using anodic bonding of a glass lid or using metal soldering. Metal soldering enables the use of solder bumps to provide electrical connections for the package to the lid with integrated device functionality used for sealing. Hermetically sealed silicon packages eliminates the need for an extra packaging layer required in plastic packages and provides a standard interface for enclosing one or more discrete devices.

摘要： Apparatus and methods for providing solder pillar bumps. Pillar bump connections are formed on input/output terminals for integrated circuits by forming a pillar of conductive material using plating of a conductive material over terminals of an integrated circuit. A base portion of the pillar bump has a greater width than an upper portion. A cross-section of the base portion of the pillar bump may make a trapezoidal, rectangular or sloping shape. Solder material may be formed on the top surface of the pillar. The resulting solder pillar bumps form fine pitch package solder connections that are more reliable than those of the prior art.

摘要： Methods, techniques, and structures relating to die packaging. In one exemplary implementation, a die package interconnect structure includes a semiconductor substrate and a first conducting layer in contact with the semiconductor substrate. The first conducting layer may include a base layer metal. The base layer metal may include Cu. The exemplary implementation may also include a diffusion barrier in contact with the first conducting layer and a wetting layer on top of the diffusion barrier. A bump layer may reside on top of the wetting layer, in which the bump layer may include Sn, and Sn may be electroplated. The diffusion barrier may be electroless and may be adapted to prevent Cu and Sn from diffusing through the diffusion barrier. Furthermore, the diffusion barrier may be further adapted to suppress a whisker-type formation in the bump layer.

摘要： A die and a substrate are provided. The die comprises at least one integrated circuit chip, and the substrate comprises first and second subsets of conductive pillars extending at least partially therethrough. Each of the first subset of conductive pillars comprises a protrusion bump pad protruding from a surface of the substrate, and the second subset of conductive pillars each partially form a trace recessed within the surface of the substrate. The die is coupled to the substrate via a plurality of conductive bumps each extending between one of the protrusion bump pads and the die.
