UK process startup looks for fab partners

UK process technology developer Search for the Next (SFN) has launched four libraries that it says can boost the performance of older chip-making technologies, and is looking for fab partners.

The libraries combine the company’s Bizen wafer process, Zpolar transistor and Zpolar Tunnel Logic (ZTL) into something SFN calls an ‘Infrastructure Time Machine’ (ITM).

The ITM contains the fully-characterized device libraries (LIB) and Process Development Kit (PDK) to the foundries to make ZTL chips. The Bizen technology has been tested and characterised at Semefab in Scotland, although SFN does not yet have test chips from the ITMs and is looking to license the technology to fab operators.

“We are aware of CMOS technology roads stretching out to at least 2036 with device geometries down to two angstroms.  It is important to understand CMOS is logic, MOS a transistor. Even CFETS are stacked nMOS and pMOS. Zpolar transistors move away from a reliance on the unipolar structure of CMOS, to take advantage of an inherent hair trigger input and minimized vertical size,” said David Summerland, CEO of SFN (above).

The ITM180 library can deliver ZTL chips with the performance of 180nm CMOS using one micron equipment says Summerland. ITM35 works on 180nm process node fabs while ITM5 works with 28nm steppers.
