Method for forming semiconductor package structure with twinned copper layer

摘要

A semiconductor package structure is provided. The semiconductor package structure includes a chip structure. The semiconductor package structure includes a first conductive structure over the chip structure. The first conductive structure is electrically connected to the chip structure. The first conductive structure includes a first transition layer over the chip structure, and a first conductive layer on the first transition layer. The first conductive layer is substantially made of twinned copper.
