Abstract:
A method for avoiding processing damage to an etched damascene feature in a reworking process comprising the steps of:providing a substrate comprising a dielectric insulating layer and a first etched opening formed in closed communication with an underlying conductive area the first etched opening being at least partially filled with a plug of first resinous polymeric material; providing a first photoresist layer over the first etched opening the first photoresist layer photolithographically patterned for forming a second etched opening overlying the first etched opening; forming a resinous layer of second resinous polymeric material over the first photoresist layer in a reworking process to include filling a remaining portion of the first etched opening; removing the resinous layer and the first photoresist layer in a planarizing process to reveal an upper surface of the substrate; and, forming a second photoresist layer over the upper surface and photolithographically re-patterning the second photoresist layer for forming the second etched opening overlying the first etched opening.
