A reusable burn-in/test fixture for discrete TAB die consists of two halves. The first half of the test fixture contains cavity in which die is inserted. When the two halves are assembled, the fixture establishes electrical contact with the die and with a burn-in oven. The test fixture need not be opened until the burn-in and electrical test are completed. The fixture permits the die to be characterized prior to assembly.

A method and apparatus for wire bonding bond pads formed on semiconductor dice to the lead fingers of a semiconductor leadframe are provided. Using an automated wire bonding apparatus two (or more) adjacent dice attached to the leadframe are wire bonded using a single indexing step for the leadframe. The wire bonding apparatus includes a heat block for heating the two adjacent dice, and a clamp for clamping the two adjacent dice to the heat block for wire bonding. A bonding tool of the wire bonding apparatus is moved to successively wire bond the two adjacent dice. The method of the invention is suitable for DIP, ZIP, SOJ, TSOP, PLCC, SOIC, PQFP, or IDF semiconductor packages.

A multi-layered semiconductor structure with free areas limiting the placement of test keys. First and second scribe lines intersect to define one corner point of a die. The first and second scribe lines are part of the multilayered structure and at least one layer of the multi-layer structure is a low-k dielectric layer. Free area A1 is defined on the first scribe line and is defined by the equation A1=D1×S1, where D1 is the distance from the corner point of the die toward the main area of the die, and S1 is the width of the first scribe line. Free area AS is defined at the intersection of the first scribe line and the second scribe line adjacent the die and is defined by the equation AS=S1×S2, where S2 is the width of the second scribe line.

摘要:
A stacked semiconductor device, and method of making, having a plurality of semiconductor chips of desired sizes stacked as one package, a first semiconductor chip is mounted on a first substrate. Solder balls are connected to contacts on the upper surface of the first substrate and a non-conductive layer is provided overlaying the first substrate and the first semiconductor chip. The solder balls are secured in cavities formed in the layer and extend beyond the top surface of the layer. A second semiconductor chip mounted on a second substrate is stacked on the layer with contacts on the lower surface of the second substrate in electrical contact with the extended portion of the solder balls, thereby connecting the second semiconductor chip with the first semiconductor chip.
