Smoltek has received a new patent for improving the capacitance density of our CNF-MIM capacitors. This innovation, a type of capacitor, can increase the capacitance density by two to three times, which is crucial for Smoltek's business and technology growth.
The patent is the first one in a new catÂeÂgoÂry called MulÂtiÂlayÂer Cap, and describes a method for creÂatÂing a layÂered capacÂiÂtor using a metÂal-insuÂlaÂtor-metÂal (MIM) strucÂture. This method involves stackÂing conÂducÂtor-insuÂlaÂtor layÂers to enhance capacÂiÂtance denÂsiÂty, a key feaÂture of Smoltek’s CNF-MIM capacÂiÂtor technology.
CapacÂiÂtance denÂsiÂty is one of the most imporÂtant KPIs of our CNF-MIM capacÂiÂtor techÂnolÂoÂgy. In this new patent, we proÂpose a techÂnique that douÂbles or triples the capacÂiÂtance denÂsiÂty through an innoÂvatÂing mulÂti-layÂer structure.
Farzan GhaÂvaniÂni, CTO at Smoltek.
The patent disÂclosÂes a disÂcrete metÂal-insuÂlaÂtor-metÂal (MIM) capacÂiÂtor comÂpoÂnent based on the proÂpriÂetary carÂbon nanofiber techÂnolÂoÂgy develÂoped at Smoltek. It also describes the strucÂture of such capacÂiÂtor and the relatÂed microÂfabÂriÂcaÂtion processÂes to realÂize it
The patent includes two main claims: one for the strucÂture of the capacÂiÂtor and anothÂer for the manÂuÂfacÂturÂing process. This invenÂtion focusÂes on improvÂing metÂal-insuÂlaÂtor-metÂal (MIM) capacÂiÂtors and batÂterÂies, includÂing capacÂiÂtors and batÂterÂies, through a new, innoÂvÂaÂtive mulÂti-layÂer structure.
Smoltek’s patent portÂfoÂlio now globÂalÂly comÂprisÂes 90 grantÂed patents. Read more about our IP and patents.
