Understanding Semiconductor Wafer Probing: Methods, Troubles, and Future Perspectives
1. Introduction to Semiconductor Wafer Probing
Semiconductor wafer probing is an essential stage within the semiconductor manufacturing method. This is a screening strategy applied To judge the electrical performance of the semiconductor wafer, typically employing a probe card to produce a short term electrical link among the tests machines as well as system beneath exam.
two. The entire process of Semiconductor Wafer Probing
Semiconductor wafer probing might be executed manually or immediately, depending on the complexity and prerequisites with the undertaking.
Guide Probing
In manual probing, a technician manually positions the probe needles above unique factors within the wafer. This method gives flexibility but is frequently time-consuming and liable to human error.
Automated Probing
Automatic probing will involve the use of specialised gear to place the probe needles precisely. This method is faster plus much more responsible than handbook probing and is also ever more favored for high-quantity testing.
