Probuilt wafer testing
A wafer prober is a machine used for integrated circuits verification against designed functionality. It's either manual or automatic test equipment. For electrical testing a set of microscopic contacts or probes called a probe card are held in place whilst the wafer, vacuum-mounted on a wafer chuck, is moved into electrical contact. When a die (or array of dice) have been electrically tested th… WebbFull test at wafer probe obtains yield information as quickly as possible so any yield-improving changes can be fed back into the fab process immediately. Finally, emerging …

WebbThat job goes to the wafer prober. An automated machine solely used to test integrated circuits in the manufacturing process. To use the machine for testing, the silicon wafer is vacuum sealed on a wafer chuck, which is a round device that is meant to be a little bit bigger than the wafer. WebbSemiconductor probe cards, used in wafer-level IC testing, are the contact interface between the semiconductor test equipment and the bonding pads of the devices under test. Probe cards are normally mounted onto a wafer prober, and connected to the tester.
