Wafer Test
Silicon Turnkey Solution, Inc. (STS)
Most foundries provide wafers already probed to a set of DC parameters at room temperature to ensure they meet a basic subset of the package-part specification. Beyond this basic set of tests, more rigorous testing is often needed to meet specifications requiring die to be 100 percent probed, identify and segregate devices with higher performance levels and guarantee that parts will perform to a certain specification level.
