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.
Smoltek’s 71st patent has been granted in Korea and is covering the invention and manufacturing of extremely thin energy storage devices embedded in an interposer. Our energy storage device concepts may take many forms e.g. discrete, integrated, or it can take the form where the end result is an interposer with CNF-MIM capacitors embedded in it.
“This is the fourth granted patent from our second wave of patent filings that protect our CNF-MIM capacitor technology and various use cases for the same, primarily in the area of semiconductors and electronics”, says Karl Lundahl, VP Product Management and Industrialization at Smoltek.
Smoltek’s inventions in the area of semiconductors and electronics facilitate integration of extremely low-profile solid state energy storage devices, such as CNF-MIM capacitors, closer to the connection points and power rails of the active chips. The CNF-MIM-technology offers the smallest form-factor for integrated high-performance capacitors by providing very high capacitance per area at a fragment of height compared with today’s technologies.
Interposers are frequently used in today’s advanced packaging architectures for integrated circuits,. The present patented concepts are built on the need to improve circuit performance by enabling a compact energy storage to be fabricated and embedded into an interposer substrate.
Smoltek’s patent portfolio now globally comprises 71 granted patents.
