Abstract:
In one embodiment, a method of forming a current sensor device includes forming a device region comprising a magnetic sensor within and/or over a semiconductor substrate. The device region is formed adjacent a front side of the semiconductor substrate. The back side of the semiconductor substrate is attached over an insulating substrate, where the back side is opposite the front side. Sidewalls of the semiconductor substrate are exposed by dicing the semiconductor substrate from the front side without completely dicing the insulating substrate. An isolation liner is formed over all of the exposed sidewalls of the semiconductor substrate. The isolation liner and the insulating substrate include a different material. The method further includes separating the insulating substrate to form diced chips, removing at least a portion of the isolation liner from over a top surface of the device region, and forming contacts over the top surface of the device region.

Abstract:
A segmented edge protection shield for plasma dicing a wafer. The segmented edge protection shield includes an outer structure and a plurality of plasma shield edge segments. The outer structure defines an interior annular edge configured to correspond to the circumferential edge of the wafer. Each one of the plurality of plasma shield edge segments is defined by an inner edge and side edges. The inner edge is interior to and concentric to the annular edge of the outer structure. The side edges extend between the inner edge and the annular edge.
