Philip Lessner, CTO at YAGEO Group says in an interview that he and Yageo sees a lot of potential in Smotek's disruptive CNF-MIM capacitor technology for making capacitors in extremely small form factors.
In an interview, first published in a German tech magazine, in July this year, Philip Lessner, CTO at Yageo Group spoke about the plans they have for technology and market leadership.
In the article, he also speaks about the advantages with Smoltek’s CNF-MIM capacitor technology:
In the past, there have been few passive device activities that have used semiconductor process technology to produce passive devices. Ipedia is probably the best known. Our goal is also to map the functions of passive components in semiconductors. In collaboration with Smoltek Semi, we build carbon nanofibers on 8-inch silicon wafers, with the rest of the processing done as part of a normal CMOS process technology. Such a wafer would then probably provide us with 48,000 CNF-MIM capacitors of size 0402.
