Etch back of interconnect dielectrics

摘要

An embodiment of the invention is a metal layer 14 of a back-end module 6 where the height of the interconnects 17 is greater than the height of the dielectric regions 20. Another embodiment of the invention is a method of fabricating a semiconductor wafer 4 where the height of the interconnects 17 is greater than the height of the dielectric regions 20.
