(2) 3D Heterogeneous Integration Every logic generation needs to add new functions in each node to keep unit price constant (to preserve margins). This is getting more difficult due to the following challenges: • Little functions left on board/system to co-integrate • Heterogeneous cores specialized per function—specialized performance improvement requirements needed per each dedicated core • Off-package memories—costly to co-integrate with logic, technology not fitting to baseline CMOS (where wafer/die-level stacking might be needed) Die cost reduction has been enabled so far by concurrent scaling of poly pitch, metal pitch, and cell height scaling. This would like to continue until 2024. Cell height scaling would likely to be pursued by 3D device (e.g., finFET and lateral GAA), device stacking, 3DVLSI, and design-technology-co-optimization (DTCO) constructs in cell and physical design. However, this scaling route will become challenged by diminishing electrical/system benefits and also by diminishing areareduction/$ at SoC level. Therefore, it is necessary to pursue 3D integration routes such as device-over-device stacking and/or monolithic 3D (or sequential integration) These pursuits will maintain system performance and power gains while maintaining the cost advantages such as treating expensive non-scaled components somewhere else and using the best technology fit per tier functionality. 3DVLSI offers the possibility to stack devices enabling high-density contacts at the device level (up to 100 million vias per mm² with N14 ground rules). 3DVLSI can be routed either at gate or transistor levels. The partitioning at the gate level allows IC performance gain due to wire length reduction while partitioning at the transistor level by stacking nFET over pFET (or the opposite), enabling the independent optimization of both types of transistors (customized implementation of channel material/substrate orientation/channel and raised source/drain strain, etc.) while enabling reduced process complexity compared to a planar co-integration, for instance the stacking of III-V nFETs above SiGe pFETs. These high mobility transistors are well suited for 3DVLSI because their process temperatures are intrinsically low. 3DVLSI, with its high contact density, can also enable applications requiring heterogeneous co-integration with high-density 3D vias, such as NEMS with CMOS for gas sensing or highly miniaturized imagers. In order to address the transition from 2D to 3DVLSI, the following generations are projected in the IRDS roadmap: • Die-to-wafer and wafer-to-wafer stacking o Approach: Fine-pitch di-electric/hybrid bonding and/or flip-chip assembly o Opportunities: Reducing bill-of-materials on the system, heterogenous integration o Challenges: Design/architecture partitioning • N&P stacking o Approach: Sequential integration o Opportunities: Reducing 2D footprint of standard cell o Challenges: Minimizing interconnect overhead is key between N&P enabling low-cost • Adding logic 3D SRAM and/or MRAM stack (embedded/stacked) o Approach: Sequential integration and/or wafer transfer o Opportunities: 2D area gain, better connection between logic and memory enabling system latency gains. o Challenges: Solving the thermal budget of interconnect at the lower tier if stacking approach is used, Revisiting the cache hierarchy and application requirements, power, and clock distribution • Adding Analog and I/O o Approach: Sequential integration and/or wafer transfer o Opportunities: Giving more freedom to designer and allows integration of high-mobility channels, pushing non-scaling components to another tier, IP re-use, scalability, IO voltage enablement in advanced nodes o Challenges: Thermal budget, reliability requirements, power and clock distribution • True-3D VLSI: Clustered functional stacks, beyond CMOS adoption o Approach: Sequential integration and/or wafer transfer o Opportunities: Complementary functions other than CMOS replacement such as neuromorphic, highbandwidth memory. Application examples include image recognition in neuromorphic fabric and wideIO sensor interfacing (e.g., DNA sequencing, molecular analysis). o Challenges: Architecting the application where low energy at low frequency and highly-parallel interfaces could be utilized, mapping applications to non-Von Neumann architectures. 1) Which of the following may not be the challenge to add new functions in each node of logic generation?
