Abstract
In one embodiment, a testing regimen is implemented to reduce test time. Specifically, a structure and method to power up and stabilize all die on the wafer prior to testing each die is implemented. More specifically, parallel powering schemes including die stabilization procedures are used to ready the wafer for testing. A wafer probe tester is indexed from one die to the next for an uninterrupted testing of all die in the wafer subsequent to all die power up and stabilization.
