WebA probe card is essentially an interface or a board that is used to perform wafer test for a semiconductor wafer. It is used to connect to the integrated circuits located on a wafer to … WebYield: Fraction of acceptable parts among all fabricated parts. Production (go/no-go test) Less intensive test performed on every chip. Main driver is cost -- test time MUST be minimized. Tests must have high coverage of modeled faults. No fault diagnosis, only an outgoing inspection test.
WebJun 28, 2024 · Any increase in the number of working chips on a wafer, after all, directly impacts the bottom line. However, as chip designers work to pack more transistors onto their chips and take advantage of new packaging technologies, the chips become more challenging to manufacture—and a high yield becomes more difficult to attain. Once the front-end process has been completed, the semiconductor devices or chips are subjected to a variety of electrical tests to determine if they function properly. The percent of devices on the wafer found to perform properly is referred to as the yield. Manufacturers are typically secretive about their yields, but it can be as low as 30%, meaning that only 30% of the chips on the wafer work as intended. Process variation is one among many reasons for low yield…
