Abstract

The invention provides a method of fabricating a semiconductive device [200]. In this embodiment, the method comprises depositing a hydrocarbon layer [294] over a semiconductive substrate, forming an interconnect structure [295, 297] within the hydrocarbon layer [294], and removing the hydrocarbon layer [294] by sublimation.
