This is an impor­tant step towards licens­ing the tech­nol­o­gy con­cept to cus­tomers in the semi­con­duc­tor and elec­tron­ics indus­tries. And it will put Smoltek in an attrac­tive mar­ket position. 

Smoltek presents new mea­sure­ments from the nan­otech­nol­o­gy research con­duct­ed by the com­pa­ny at Chalmers Uni­ver­si­ty of Technology’s MC2 lab­o­ra­to­ry, in Gothenburg.

Smoltek can now demon­strate a num­ber of capac­i­tor pro­to­types, based on car­bon nanofibers with a capac­i­tance den­si­ty of 200nF (nano­Farad) per square mil­lime­ter. The val­ue is two and a half times greater than the pre­vi­ous­ly ver­i­fied num­ber, which the com­pa­ny pre­sent­ed as recent­ly as in May this year, and has been achieved with short nanos­truc­tures, which gives a very low over­all pro­file height, an inte­gra­tional advantage.

Smoltek can also con­firm low inter­nal resis­tance (ESR), an impor­tant para­me­ter for prac­ti­cal use of the con­cept. The com­pa­ny has already demon­strat­ed that the tech­nol­o­gy meets required break-down volt­age for the actu­al appli­ca­tion areas of interest.

“This is a very impor­tant step for Smoltek, as it increas­es the attrac­tive­ness of our tech­nol­o­gy in the cus­tomer dia­logues in progress,” says Anders Johans­son, CEO of Smoltek Nan­otech Hold­ing AB. He fur­ther states that there are still opti­miza­tion oppor­tu­ni­ties in the con­cept for the future.

“The new mea­sure­ment results con­firm Smoltek’s lead­ing posi­tion in inno­v­a­tive tech­nol­o­gy for inte­grat­ed pas­sive ele­ments. They again show that our capac­i­tor tech­nol­o­gy is high­ly rel­e­vant to meet­ing the chal­lenges of future inte­grat­ed cir­cuits – high­er per­for­mance on small­er sur­faces”, says CTO Pro­fes­sor Vin­cent Desmaris.

To sum­ma­rize: Sim­ply expressed, the capac­i­tance den­si­ty refers to how many elec­trons can be stored per sur­face unit. That a high­er val­ue is mea­sured means that the desired per­for­mance of a capac­i­tor can be achieved on a small­er surface.
