    摘要: A technique is described for improving metal-organic substrate adhesion and for reducing stress between the metal film and the substrate. Low energy reactive ions, electrons, or photons are incident upon the substrate to alter the surface chemistry of the substrate to a depth of from about 10 angstroms to a few hundred angstroms. The energy of the incident reactive ions and electrons is about 50-2000 eV, while the energy of the incident photons is about 0.2-500 eV. Irradiation of the substrate can occur prior to or during metal deposition. For simultaneous metal deposition/particle irradiation, the arrival rates of the metal atoms and the substrate treatment particles are within a few order of magnitude of one another. Room temperatures or elevated temperatures are suitable.

    摘要: Electromigration can be reduced in a copper-based metallization of an integrated circuit that includes a first copper-containing via that electrically connects an underlying conductive line and an overlying copper-containing line through an intervening insulating layer. Electromigration can be reduced by forming at least a second copper-containing via that electrically connects the underlying conductive line and the overlying copper-containing line through the intervening insulating layer, in parallel with the first copper-containing via. Multi-vias can provide redundancy to reduce early failure statistics. Moreover, since current is distributed among the vias, the electromigration driving force can be reduced and local Joule heating, in voids at the via interface, also may be reduced. Accordingly, even if via voids are formed, the structure may not fail by catastrophic thermal runaway due to Joule heating.

    摘要: The disclosure relates to a method for forming a nanoscale structure by forming a pattern on a selectively etched layer located on top of a substrate using lithography, wherein the pattern results a gap having sidewalls, performing RIE on the gap having sidewalls, wherein RIE results in the formation of a self-aligned mask on the bottom wall of the gap with unprotected regions on the bottom wall of the gap near the junctions with the sidewalls, and wet etching the gap having a self-aligned mask and unprotected regions to remove the substrate under the unprotected regions to form a nanoscale structure in the substrate.The disclosure also relates to a nanoscale structure array including a plurality of nanotrenches, nanochannels or nanofins having a width of 50 nm or less and an average variation in width of 5% or less along the entire length of each nanotrench, nanochannel or nanofin.
