Recently, Intel OEM announced a major breakthrough in on-chip interconnection technology. The latest subtractive Ruthenium interconnection technology of the company can reduce the inter-line capacitance by up to 25%, effectively improving the on-chip interconnection. According to reports, the subtractive ruthenium interconnection technology has achieved great progress in interconnection miniaturization by using ruthenium, a new, key and alternative metallization material, and using thin film resistivity and airgap. This process does not need an expensive photolithographic air gap exclusion zone around the via, and it can also avoid using a self-aligned via that is selectively etched. When the spacing is less than or equal to 25 nm, the air gap realized by reducing ruthenium interconnection technology can reduce the capacitance between lines by up to 25%, which can be used as a metallization scheme to replace copper damascene process in closely spaced layers. It is reported that this solution is expected to be applied in the future process nodes of Intel OEM.
