Cost reduction at sophisticated node through ESD intermediate switch

摘要

A device including an electrostatic discharge circuit including a first circuit portion coupled below a die pad of an integrated circuit die and a second circuit portion in an intermediate switch separate from the integrated circuit die, the intermediate switch having a first contact point is coupled to the pad of the integrated circuit die, and includes a second contact point operable to connect to an external source. A method including forming an integrated circuit die including a first electrostatic discharge structure beneath a contact pad of the dies; and coupling the dies to an interposer including an interposer switch contact and a second electrostatic discharge structure, wherein a signal at the contact pad of the die is operable to be routed through the interposer.
