Company Description (as filed with the SEC)
We design, develop, manufacture, sell and support precision, high performance advanced semiconductor wafer probe card products and solutions. We are the largest probe card manufacturer, and semiconductor manufacturers use our wafer probe cards in the semiconductor manufacturing process to perform sort and test on the semiconductor die, or chips, on a semiconductor wafer. During wafer sort and test, a wafer probe card is mounted on a prober and electrically connected to a semiconductor tester. The wafer probe card is used as an interface to connect electrically with and test individual chips on a wafer. Using our wafer probe cards to test at this stage of the manufacturing process, our customers can reduce their cost of test by identifying defective chips prior to incurring the time and costs of packaging defective chips. ...
