What it is
How it works
General reference — not yet source-verifiedThe MM 9920 operates by aligning a wafer on a chuck and bringing probe needles into contact with bond pads or test structures on the die. The prober then steps to each die location, making measurements via an attached test system. The MM 9920 likely includes a microscope for alignment and visual inspection.
Where it fits in the process flow
General reference — not yet source-verifiedWafer probing is performed after wafer fabrication and before assembly and packaging. The process step is known as wafer sort or electrical die sort. The prober interfaces with an automatic test equipment system to execute parametric and functional tests on every die on the wafer.
Applications
General reference — not yet source-verifiedThe MM 9920 is used in semiconductor test for wafer sort, characterization, and failure analysis. The prober can be applied to logic, memory, analog, or mixed-signal device testing. The prober also supports process monitoring and reliability testing at the wafer level.
