Interesting to see Zettacore raising a $21m series C, some six years after they first started our promising to replace silicon with molecular memories, although that’s not the application that is attracting interest right now.
As Nikkei Electronics reported last week – they look to have a customer for their Molecular Interface (aren’t most interfaces molecular?) technology that helps with conventional semiconductor manufacturing. While their initial plan for global domination of the memory business seems to have been elbowed aside with the fall in price of flash memory from a dollar a Mb 2001 to less than a dollar a Gb 2009, the R&D does seem to have been useful for something…
ZettaCore said MI technology enables deposition of copper on smooth dielectric, and lamination of dielectric on smooth copper in high-performance IC substrates, HDI boards, high-speed boards, flexible PCBs, and wafer level packaging. Since surface roughening is eliminated, customers can realize finer line/space dimensions and improve signal integrity while using conventional materials and processes.
“ZettaCore MI technology offers IC substrate customers the ability to leverage their manufacturing infrastructure and yet realize finer line/space design rules. For example, customers can advance interconnect geometries with the current GX-13 material beyond what is possible with conventional roughening technologies. Since the interfaces are smooth, losses related to skin effect are minimized which would improve system performance,” said Takao Sakurai, general manager of Specialty Chemical Dept, Ajinomoto Co Inc.
By working with Ajinomoto, ZettaCore is offering a complete and seamless solution to substrate manufacturers.
“Ajinomoto GX-13 build-up resin has a dominant market share in flip-chip IC substrates. Customers can now realize 10µm line/space design rules and beyond by using ZettaCore MI technology in conjunction with GX-13 material,” said Srinivas Nimmagadda, VP of Business Development at ZettaCore.
That’s another set of rebels assimilated into the world of CMOS then.
