Smoltek patent No. 77 now granted

Smoltek’s 77^th patent has been grant­ed in Japan and is cov­er­ing the inven­tion and man­u­fac­tur­ing of extreme­ly thin ener­gy stor­age devices embed­ded in an interposer. 

Our 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. 

Tra­di­tion­al­ly, an inter­pos­er is used only to make redis­tri­b­u­tions lay­ers (RDL) or inter­con­nects for oth­er dies to be con­nect­ed. With our patent­ed con­cept, it will be pos­si­ble to make the inter­pos­er hav­ing ener­gy stor­age devices e.g. capac­i­tors, sol­id state micro bat­ter­ies etc. embed­ded with­in the inter­pos­er struc­ture. This allows not only to have inter­pos­er with inter­con­nects but also with ener­gy storage. 

“The appli­ca­tions of such inter­posers are antic­i­pat­ed to steadi­ly grow in the field of Het­ero­ge­neous Inte­gra­tion. And in this case, our com­pact ener­gy stor­age inter­pos­er fam­i­ly is com­ple­men­tary to our Inter­pos­er fam­i­ly, and offers an alter­na­tive path to uti­lize our CNF-MIM tech­nol­o­gy pri­mar­i­ly to man­u­fac­ture inter­posers. The beau­ty of our con­cept is that it facil­i­tates to make an inter­pos­er smarter with added func­tion­al­i­ty embed­ded with­in the inter­pos­er. Quite mind­bog­gling, actu­al­ly”,

says Farzan Gha­vani­ni, CTO and Head of R&D at Smoltek.
