3D Integration of CMOL Structures for FPGA Applications

In this paper, a novel 3D CMOS nanohybrid technology, 3D CMOL, is introduced to establish FPGA chips. By combining two leading technologies, hybrid CMOS/nanoelectronic circuit (CMOL) and 3D integration, 3D CMOL can provide a feasible and more efficient fabrication/assembly process than the existing 2D CMOL. Furthermore, 3D CMOL FPGA implements circuits in three dimensions so that it can increase the density of the nanodevices and achieve higher performance compared to 2D CMOL and field programmable nanowire interconnect (FPNI). This paper presents the architecture optimization, 3D integration, defect tolerance, and performance evaluation of 3D CMOL FPGA. It is expected that this technology can lead to technology breakthroughs towards the development of the next FPGA generation.
