Technology-Independent RHBD Library Through Gate Array Approach

As semiconductor technology nodes scale down, the limitation on polysilicon pitch makes it almost impossible to shrink libraries built for previous technologies. To design a library for a new technology, all of the cells have to basically start from scratch. Starting over for each technology node shrink is time-consuming and expensive. Further, obtaining space qualification for a technology node will require significant time and money. If a RHBD (radiation-hardened-by-design) library gates invention shares the same transistor structured as the SASIC (Structured Application-Specific Integrated Circuit), it will benefit from the existing qualification effort and high-performance advanced technology of the SASIC design flow.
