Skybridge-3d-Cmos: A Fine-Grained Vertical 3d-Cmos Technology Paving New Direction For 3d Ic, Jiajun Shi

Doctoral Dissertations

2D CMOS integrated circuit (IC) technology scaling faces severe challenges that result from device scaling limitations, interconnect bottleneck that dominates power and performance, etc. 3D ICs with die-die and layer-layer stacking using Through Silicon Vias (TSVs) and Monolithic Inter-layer Vias (MIVs) have been explored in recent years to generate circuits with considerable interconnect saving for continuing technology scaling. However, these 3D IC technologies still rely on conventional 2D CMOS’s device, circuit and interconnect mindset showing only incremental benefits while adding new challenges reliability issues, robustness of power delivery network design and short-channel effects as technology node scaling. Skybridge-3D-CMOS (S3DC) is …

As the scaling of CMOS approaches fundamental limits, revolutionary technology beyond the end of CMOS roadmap is essential to continue the progress and miniaturization of integrated circuits. Recent research efforts in 3-D circuit integration explore pathways of continuing the scaling by co-designing for device, circuit, connectivity, heat and manufacturing challenges in a 3-D fabric-centric manner. SkyBridge fabric is one such approach that addresses fine-grained integration in 3-D, achieves orders of magnitude benefits over projected scaled 2-D CMOS, and provides a pathway for continuing scaling beyond 2-D CMOS.

However, SkyBridge fabric utilizes only single type transistors in order to reduce manufacture …
