    • The present invention provides, in one aspect, a method for fabricating an interconnect system within a semiconductor device. In this particular embodiment, the method comprises forming a conductive layer over a substrate of the semiconductor device, such as a dielectric material, forming a photoresist layer over the conductive layer and patterning the photoresist, forming a selected portion and an unselected portion of the conductive layer, altering the selected portion such that the selected portion has an etch rate different from an etch rate of the unselected portion, and forming an interconnect on the selected or unselected portion. As used herein, the selected portion is defined as that portion of the conductive layer, such as a blanket seed layer, that is subject to the alteration process as discussed herein. The selected portion may be, depending on the embodiment, within a footprint of the interconnect or outside the footprint of the interconnect.
    • 本发明在一个方面提供一种在半导体器件内制造互连系统的方法。 在该特定实施例中,该方法包括在半导体器件的衬底(例如电介质材料)的上方形成导电层,在导电层上形成光致抗蚀剂层并构图光致抗蚀剂,形成导电的选定部分和未选择的部分 改变所选择的部分,使得所选择的部分具有与未选择部分的蚀刻速率不同的蚀刻速率,以及在所选择的或未选择的部分上形成互连。 如本文所使用的,所选择的部分被定义为如本文所讨论的改变过程的导电层(例如覆盖种子层)的那部分。 取决于实施例,所选择的部分可以在互连的占用面积内或互连的占地面积之外。
