Smoltek’s inven­tions facil­i­tate inte­gra­tion of extreme­ly thin sol­id-state ener­gy stor­age devices, CNF-MIM capac­i­tors, clos­er to the inter­con­nec­tion points and pow­er rails of the active chips. The CNF-MIM tech­nol­o­gy offers the industry’s small­est form­fac­tor for high-per­for­mance capac­i­tors by pro­vid­ing a very high capac­i­tance per area at a frag­ment of the height com­pared to today’s technologies.

In the semi­con­duc­tor indus­try the Advanced Pack­ag­ing and Het­ero­ge­neous Inte­gra­tion con­cepts offers archi­tec­tures for increased func­tion­al­i­ty and enhanced per­for­mances on a sys­tem lev­el togeth­er with an ever-small­er foot­print. Inter­posers are impor­tant build­ing-blocks in these archi­tec­tures. Sil­i­con inter­posers have so far main­ly been uti­lized for high-end semi­con­duc­tors such as high-per­for­mance GPUs, CPUs, FPGAs, and HBMs, while the mid-end seg­ment has a greater share of organ­ic inter­posers due to cost issues. The point is that inter­posers today is a key sub-com­po­nent and a main sta­ple technology.

With this new­ly grant­ed patent, we are expand­ing our inter­pos­er-relat­ed pro­tec­tion scheme on the US market.

“Inter­posers are fre­quent­ly and increas­ing­ly used in advanced semi­con­duc­tor prod­ucts. We are hap­py to make our tech­nol­o­gy even more rel­e­vant to the indus­try by facil­i­tat­ing fur­ther improved per­for­mance and there­by adding sig­nif­i­cant val­ue.”, says Dr Shafiq Kabir, Founder and Chief Inno­va­tion Offi­cer at Smoltek.

Tra­di­tion­al­ly, an inter­pos­er has been used only for pas­sive redis­tri­b­u­tions lay­ers (RDL) or inter­con­nects for oth­er dies to be con­nect­ed. Over time oth­er pas­sive func­tion­al­i­ty has been added, such inter­posers are often referred to as “smart inter­posers”. Our patent­ed con­cept com­pris­es ener­gy stor­age devices, e.g. capac­i­tors, sol­id state micro bat­ter­ies etc., to be embed­ded in the inter­pos­er structure.

The mar­ket for such inter­posers is antic­i­pat­ed to steadi­ly grow in the field of Advanced Pack­ag­ing and Het­ero­ge­neous Inte­gra­tion. Our Com­pact Ener­gy Stor­age Inter­pos­er fam­i­ly is com­ple­men­tary to our oth­er Inter­pos­er fam­i­lies and offers an addi­tion­al path to uti­lize our CNF-MIM technology.
