Abstract

One or more probe cards, wafer testers, and techniques for testing a semiconductor arrangement are provided. Testline arrangements are formed within scribe lines of a semiconductor wafer, in multiple directions, such as an x-direction and a y-direction. A wafer tester is configured to concurrently test the semiconductor arrangement in multiple directions using a multidirectional probe arrangement of a probe card. In some embodiments, a first pin arrangement of the multidirectional probe arrangement is mated with a first testline arrangement in a first direction, and a second pin arrangement of the multidirectional probe arrangement is mated with a second testline arrangement in a second direction. The wafer tester concurrently tests the semiconductor arrangement in multiple directions, such as in the first direction and the second direction, through the pin arrangements mated with the testline arrangements.
