Abstract
A low-k dielectric porous silicon oxycarbon layer is formed within an integrated circuit. In one embodiment, a porogen and bulk layer containing silicon oxycarbon layer is deposited, the porogens are selectively removed from the formed layer without simultaneously cross-linking the bulk layer, and then the bulk layer material is cross-linked. In other embodiments, multiple silicon oxycarbon sublayers are deposited, porogens from each sub-layer are selectively removed without simultaneously cross-linking the bulk material of the sub-layer, and the sub-layers are cross-linked separately.
