摘要:
A universal system for testing different semiconductor devices provides a probe head with a probe pattern that may be used to test different test patterns formed on different semiconductor devices. Each of a plurality of bumps or pads of the test pattern contacts a corresponding probe of the probe head to enable the semiconductor device to be tested. The universal probe head may additionally or alternatively include a substrate design on the probe head that provides a pattern on the substrate of the probe head that may be used in conjunction with different patterns formed on a plurality of different printed circuit boards for testing different semiconductor devices.
摘要:
The embodiments described above provide mechanisms for bump resistivity measurement. By using designated bumps on one or more corners of dies, the resistivity of bumps may be measured without damaging devices and without a customized probing card. In addition, bump resistivity may be collected across the entire wafer. The collected resistivity data may be used to monitor the stability and/or health of processes used to form bumps and their underlying layers.
