Abstract:
Timely testing of die on wafer reduces the cost to manufacture ICs. This disclosure describes a die test structure and process to reduce test time by adding test pads on the top surface of the die. The added test pads allow a tester to probe and test more circuits within the die simultaneously. Also, the added test pads contribute to a reduction in the amount of test wiring overhead traditionally required to access and test circuits within a die, thus reducing die size.
