Smoltek patent No. 62 now granted

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.

Smoltek’s pat­ent port­fo­lio now glob­ally com­prises 62 gran­ted pat­ents. Read more about our IP and pat­ents.
