Patent ID: 7768117

Claim:
A microelectronic unit comprising: a unit structure including a semiconductor chip, said semiconductor chip including circuitry within an interior of said chip, said unit structure defining a first surface and a periphery; a first contact on said semiconductor chip connected to the circuitry; and first and second redistribution conductive pads disposed near the periphery of structure; a first redistribution conductor connected to the first redistribution conductive pad; a second redistribution conductor connected to the second redistribution conductive pad, wherein the first and second conductors extend toward and are electrically connected to the first contact and are electrically connected to one another adjacent the first contact so as to form a conductive path extending between the first and second redistribution conductive pads, the conductive path limiting reflection of a signal propagating along the conductive path between the conductive pads and the circuitry within the interior of the chip.
