Patent ID: 7768103

Claim:
A tape distribution substrate, comprising: a base film including a chip mounting portion on which a semiconductor chip is mounted; and, a plurality of distribution line pairs formed on the base film, wherein each distribution line pair comprises a first distribution line and a second distribution line respectively providing a pair of signals having opposite phases, to the semiconductor chip; wherein the first and second distribution lines of each distribution line pair each include a first portion contacting the chip mounting portion, a second portion separated from the chip mounting portion, and a third portion between the first and second portions; wherein the respective first portions of the first and second distribution lines within each distribution line pair are separated by a first distance; and, wherein the respective second portions of the first and second distribution lines within each distribution line pair are separated by a second distance that is smaller than the first distance, and wherein a distance between respective third portions of the first and second distribution lines within each distribution line pair gradually decreases in a direction away from the chip mounting portion, and a distance between respective third portions of adjacent distribution line pairs gradually increases in a direction away from the chip mounting portion.
