Ruthenium adhesion layer
WebJul 1, 2024 · A 0.3 nm thick titanium-based adhesion layer was deposited under Ru nano-interconnects. In addition, a standard Ru BEOL without airgaps and a standard Cu BEOL without airgaps but otherwise identical specifications with the Ru airgaps were processed and used for benchmarking used for mechanical benchmarking. WebIn gold interconnection schemes, an adhesion layer, typically 250–400 Å thick, is used at the gold/oxide interface. Adhesion layers are thin films of tungsten, niobium, chrome, or titanium. The gold layers are generally about 1 μm-thick. This type of metallization scheme can be planarized with a microsecond pulse at a fluence of 1 J/cm2 at ...
