Abstract:
A tape distribution substrate comprises a plurality of distribution lines formed on a base film. In one embodiment, the distribution lines comprise data lines arranged in data line pairs, wherein each data line pair carries a data signal with two different polarities. The distance between the data lines in each data line pair becomes narrower as the data lines extend away from the base film. In another embodiment, the distribution lines comprise power distribution lines, each having a body portion including several holes, and divided into one or more sub-power distribution lines connected to the base film.

Abstract:
In a bonding configuration for a semiconductor device package, the bonding angles of the bonding wires are maintained within acceptable limits, without causing an increase in the chip die size, and without necessitating the use of the corner rule. In this manner, the occurrence of shorting between adjacent bonding wires can be mitigated or eliminated, and device net die count during fabrication can be increased.
