We demonstrate the suitability of carbon nanofiber based MIM capacitors (CNF-MIM) to be implemented on various substrates such as silicon, glass and alumina for prospective use as discrete or integrated passives on chips or interposers. The capacitors themselves are only 5 μm thick. However, capacitance densities larger than 300 nF/mm2 have been measured on all substrates including a 30-μm thick silicon substrate. The 5 μm thick capacitors feature ESR values in the range of 100 mΩ, ESL below 10 pH and leakage currents as low as 0.01 nA/nF at 1 V with device breakdown at 6 V, which makes them a promising candidate both for highly integrated, multifunctional on-chip and discrete miniaturized electronic components.
Smoltek has developed the world’s thinnest discrete capacitor. 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 most amazing thing about this microscopic capacitor is its performance. One square millimeter has a capacitance of a whopping 650 nanofarads (650 nF/mm2). Read on for more details.
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.
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.
This is the third and last article in a series of three in which Smoltek founder and strategic advisor Shafiq Kabir share his personal thoughts on nanotechnology opportunities. In the previous two articles, he has addressed both the hype and the reality of carbon nanotechnology. In this last article, he looks into the future. He discusses how carbon nanotechnology will unleash the power of the internet of everything.
