CMOS transistors characterised at 77K and 4k for quantum chips
The UK CryoCMOS consortium has created high quality models of CMOS transistors at both 4K & 77K operation for the next generation of quantum chips.
UK memory designer SureCore is using the process development kit (PDK) for the GlobalFoundries 22FDX 22nm FDSOI process to develop key foundation IP to enable the design of cryo-control ASICs for use in quantum computer. Key to supporting this activity were the accurate cryogenic measurements undertaken by Incize of Louvain-la-Neuve, Belgium.
