NanoXion — The Next Generation of Nanoscale Metal Interconnects

NanoXion is building a platform for electrochemical additive manufacturing of conductive metal structures: 3 µm to 25 nm resolution, nanocrystalline copper, gold and platinum, printing at standard conditions. A planned spin-off of the University of Oldenburg.

The platform

Resolution. Structures from 25 nm, produced by direct additive manufacturing – without mask and without etching steps.
Conductivity. Highly conductive metal interconnects thanks to high material purity and nanocrystalline structures. … for materials such as copper, gold or platinum
Integration. Direct additive manufacturing at standard conditions on wafers, microarrays, MEAs, … – without cleanroom, vacuum or high temperature

Applications

Semiconductor development. Highly conductive interconnects written directly onto already processed wafers and dies — for advanced packaging, for contacting and wire bonding at feature sizes that conventional processes can no longer reach, for physical debug and for microLED fabrication.
Physical Debug. Interconnects are written, measured and then dissolved again by electrochemical oxidation, leaving no residue and no damage to the device. Many paths can be tested in sequence without shorting signal lines — high-throughput testing without returning to the cleanroom.
2D materials. On-chip writing with copper or gold on pre-fabricated circuits. Exfoliated flakes of 1–50 µm sit randomly on the chip and are contacted selectively across distances of up to 1 mm — over insulators such as Si/SiO₂ and without touching other flakes along the path. For graphene, hBN and TMDCs such as MoS₂, WS₂ or WSe₂, through to the finished FET.
Medical technology. Biocompatible metals such as gold and platinum, deposited additively as electrodes for implants and human-electronic interfaces. Small, high-density structures with low surface roughness, in a single manufacturing step instead of a multi-stage process chain.
Space research. On-demand repair of microelectronics where no spare part and no production line can be reached. Almost no external infrastructure is required: the system works standalone as a benchtop device, with minimal material consumption from an aqueous printing ink.
Photonics. Metallic micro-optics: the optical properties of metals combined with freely fabricated geometry — 2.5D to 3D, free-standing overhangs, feature sizes on the scale of single wavelengths.

About Us

NanoXion is a planned spin-off of the Carl von Ossietzky University of Oldenburg and is currently in its pre-seed founding phase. It transfers German top-level university research with international key-technology potential into industry. With application areas in semiconductor development, 2D materials research and medical research, our vision is a reform of the current technologies.
