The newly developed nanotransfer printing technique developed by NTU and KIMM is accomplished by transferring Gold (Au) nanostructure ... WebA: We do 100 percent of the product die on a given wafer for DC chip probe. If the chip probe yield is high, the test percentage can be reduced or skipped, like for HBT products to minimise test time and therefore cost. We do have RF testing capability at the die level, but there is a cost that would be incurred for that.
