Interview: Karl Lundahl on the next steps for CNF-MIM

Smoltek has devel­oped the world’s thinnest dis­crete capac­i­tor. Its total build­ing height is less than thir­ty microm­e­ters (30 µm). You have to stack ten of them on top of each oth­er to reach the same height as today’s indus­try-stan­dard when it comes to sur­face-mount­ed capac­i­tors. The capac­i­tor itself, with­out encap­su­la­tion, is a mere 0.5 to 10 µm. It...

A main goal for Smoltek Semi is to develop an industrial process for mass production of discrete CNF-MIM capacitors at contract manufacturers (foundry), including a specially designed machine for large-scale production of carbon nanofibers.

With our carbon nanofibers (CNFs) fabrication technology, we develop advanced packing solutions and ultra-miniaturized capacitors for use in the semiconductor industry.

Smoltek and the subsidiary Smoltek Semi has extended its evaluation license agreement with a global manufacturer of passive components. The parties will also define and agree upon the terms of a Memorandum of Understanding for the joint development of an industrial mass-production process for Smoltek’s ultra-thin carbon nanofiber capacitors.

Smoltek holds unique world patents for technologies that make material engineering on an atomic level possible. Smoltek has solutions that allow continued miniaturization and increased performance of semiconductors, contribute to carbon-free steel production and renewable energy storage, and enable mind control of robotic prostheses. This is a story of how Smoltek came to be.

At the annual IEEE Electronic Component and Technology Conference 2019 Smoltek presented new and improved measurement data for the CNF-MIM capacitance density – now in the range over 350nF/mm^2.

Carbon nanofibers in hydrogen electrolysis & fuel cells Hydro­gen has emerged as a key to store renew­able ener­gy and mak­ing heavy indus­try car­bon-free. Two appli­ca­tion areas of imme­di­ate vital impor­tance. The core tech­nolo­gies that make this pos­si­ble are hydro­gen elec­trol­y­sis and fuel cells. Elec­trol­y­sis con­verts elec­tric­i­ty into hydro­gen, while fuel cells con­vert the hydro­gen back to elec­tric­i­ty....

Smoltek is awarded a new patent in Korea. This patent is the fourth one of the patent family in the direction of CNF-MIM based compact energy storage on interposers. This also means that our global patent portfolio now comprises 71 granted patents.

During the year Smoltek has installed two new equipment systems for enhancing the R&D work. This will give the company long-term benefits with increased opportunities of technology development and cost efficiency.
