Smoltek has been awarded another patent in the Multilayer Cap patent family – an innovation that can double or triple the capacitance density of our CNF-MIM capacitors. This is a key factor for Smoltek's business and technology development.
The MulÂtiÂlayÂer Cap patent famÂiÂly details an invenÂtion for a layÂered enerÂgy storÂage device, specifÂiÂcalÂly a capacÂiÂtor, built using a metÂal-insuÂlaÂtor-metÂal (MIM) configuration.
With the MulÂtiÂlayÂer Cap patent famÂiÂly, we are introÂducÂing an innoÂvÂaÂtive mulÂti-layÂer strucÂture that can douÂble or triple the capacÂiÂtance denÂsiÂty, which is a key perÂforÂmance indiÂcaÂtor of our CNF-MIM capacÂiÂtor technology.
Farzan GhaÂvaniÂni, CTO at Smoltek.
The patent, grantÂed in TaiÂwan is the third grantÂed patent in this famÂiÂly, for the innoÂvaÂtion that disÂclosÂes a carÂbon nanofiber (CNF) based mulÂtiÂlayÂer MIM strucÂture in which elecÂtrodes and dielectrics are depositÂed one after anothÂer. This is a techÂnique that has potenÂtial to greatÂly increase the capacÂiÂtance denÂsiÂty and hence is conÂsidÂered imporÂtant for Smoltek busiÂness and technology.
The MulÂtiÂlayÂer Cap patent appliÂcaÂtion includes two indeÂpenÂdent claims: A device claim, that describes the stacked mulÂtiÂlayÂer capacÂiÂtor strucÂture havÂing alterÂnatÂing conÂducÂtor-insuÂlaÂtor layÂers. And a method claim, describÂing the fabÂriÂcaÂtion of such device with conÂforÂmal coatÂing on the CNFs.

Smoltek’s patent portÂfoÂlio now globÂalÂly comÂprisÂes 97 grantÂed patents. Read more about our IP and patents.
