Abstract:
A semiconductor wafer capable of simultaneous burn-in of all the dies on the semiconductor wafer, comprising:one or more conductive pads located in an inactive region of the wafer wherein the one or more conductive pads are adapted to electrically couple to an external power supply; a plurality of dies in an active region of the wafer wherein each die includes a burn in indicating apparatus, the burn-in indicating apparatus adapted to indicate a burn-in parameter; an array of scribe lines separating the plurality of dies, wherein the scribe lines include one or more scribe conductors electrically coupling the one or more conductive pads to the burn-in indicating apparatus and at least one circuit disposed on each of the plurality of dies within the active region of said wafer; and one or more conductive rings surrounding each die, wherein the one or more scribe conductors connects to the one or more conductive rings and the conductive rings, in turn, connect via die bond pads to the circuits of the plurality of dies so that each of the plurality of dies is simultaneously subjected to a burn-in test when the one or more conductive pads is electrically coupled to the external power supply.
