The group company Smoltek Semi has signed a joint development agreement (JDA) with a subsidiary of the global electronic component company Yageo group to commercialize a silicon based carbon nanofiber discrete capacitor.
The initial target application is a decoupling capacitor for microprocessor landside mounting. The target thickness for this discrete capacitor is 40 microns. Landside decoupling for microprocessors is an increasing area of interest for miniaturization within the semiconductor industry.
The capacitors are based on Smoltek’s patent protected. CNF-MIM technology and will be fabricated using a proprietary nano-fiber synthesis machine and industrial silicon foundry processes.
“We are excited to partner with a major passive component manufacturer to commercialize a product that is based on our core Carbon Nanofiber technology. We now have a perfect partner in place to complete a competitive product and industrial mass production process for our ultra-thin CNF-MIM capacitors”
says Smoltek’s CEO Håkan Persson
The JDA constitutes the next step in accordance with the Memorandum of Understanding (MoU) previously signed by the parties. In conjunction with the signing of the JDA, Smoltek Semi will receive 1.5 MUSD to be used for development activities within the framework of the partnership with Yageo.
“This partnership is an excellent opportunity to commercialize a new technology that will be used in capacitors for applications where space is at a premium and high capacitance density is required”.
Dr. Philip Lessner, Senior Vice President of Yageo group
