ABSTRACT:
A method for testing and burning-in semiconductor components such as semiconductor dice on a semiconductor wafer, is provided. The method includes the step of providing all of the components on the wafer with resilient contact structures, such as metal pins having integral spring segments. The resilient contact structures are used to test the components to identify functional and non-functional components. Following this test, the resilient contact structures on the non-functional components are deformed, such that electrical communication with the non-functional components is prevented in a subsequent burn-in test. This permits the burn-in test to be performed using “shared resources” test equipment. A deformation apparatus for deforming the resilient contact structures includes a deformation block configured to compress, bend or shape the resilient contact structures on the non-functional dice.
