WSF: 3D Heterogeneous Integration and 3D-Packaging Targeting B5G-6G mmW and Sub-THz Communication and Sensing
Organizers: Didier Belot (STMicroelectronic) / Pierre Busson (STMicroelectronic)
The 6G Telecom generation forecasts mm-wave and sub-THz applications as Fronthaul and Backhaul mm-wave and sub-THz wireless links; Reflective Intelligent Surface between mini-cell station and devices mainly in mm-wave frequency range; Short distance ultra-high data-rate mm-wave and sub-THz wireless data storage transfer; Automotive Joint communication and Sensing Radars; Health and Industrial mm-wave and sub-THz Radars and imagers; and other applications which are not yet defined. A Key challenge facing us is how to manage multi-processes dies with antennas integrated in the same object, reducing losses, and then increasing power efficiency and, at the same time targeting the cost efficiency. The workshop will discuss the trade-off Power Efficiency/Cost Efficiency of different 3D assembly strategies and will try to have a picture of the most promising research in the domain, through topics which will address as III-V GaN/Si and InP/Si, with SiGe and or CMOS Heterogeneous Integration; Wafer to Wafer; Die to Wafer, Backend of line co-integration; mm-wave sub-THz packaging, including Antenna integration, Si-Interposers, organic interposers, and other packaging 3D approach. The power efficiency can be defined as the max data rate ability, with the max distance covered by the transceiver over its power consumption, the cost efficiency is max data rate ability, with the max distance covered by the transceiver over its cost. This simple relation does not take into account the cooling equipment, if necessary, the reliability, and finally the environmental impact of the different strategies. These last points are difficult to quantify at the research level.
WSM: Future Chiplet Technology and 3D Heterogenous Integration
Organizers: Bahar Jalali Farahani (Cisco)/ Mahdi Parvizi (Cisco)/ Salvatore Finocchiaro (Qorvo)/ Ko-Tao Lee (Qorvo)
As the Moore’s law is coming to an end, separating large systems into smaller chips based on their functionality is not only a cost-benefit solution but it allows the complex system to expand beyond theoretical size limits. Although chiplet technology has been around for many years, it has not been till the rise of the AI supercomputers and the accompanied unprecedented computational demand that put the spotlight on SiPs (System in Package). There are different aspects to the design of chiplets including the packaging, the high-speed chip-to-chip interconnect and the interoperability and standardization which allow the SiP built by the combination of chips from different vendors. There are multiple benefits to the chiplet-based architectures. Breaking down the large complex systems into smaller chips based on their functionality means better yields and lower cost due to the lower probability of manufacturing defects. Cost reduction can also come with customizing the process technology for each chiplet (eg using advanced nodes for GPUs and CPUs and less expensive technologies for memories and analog interfaces). Design upgrades can also be done on certain functional blocks without the need for redesigning the whole system. To take full advantage of chiplet-based architectures, the D2D (die-to-die) interface needs to be standardized. The interoperability allows the developer to use multiple vendors. In terms of the packaging, development of 3DHI (3D Heterogeneous Integration) that enables stacking up separately manufactured components, is the perfect technology choice for chiplet-based architectures. Additionally, the ever-increasing demand for high-throughput communication links and high-resolution radar sensors is driving the development of future wireless systems at higher operating frequencies. In order to support multiple functionality, the flexibility requested to those systems, is driving the adoption of large phased array antennas. Heterogeneous technologies and vertical 3D integration will play a vital role in enhancing the performance and functional density, along with reducing the size and costs, of such RF systems. In addition to the already mentioned standardization, both on the digital and RF side, 3DHI will pose a new set of technology (processes and substrates), design (MMICS, RFIC, analog, power management, passives), packaging and thermal challenges. This workshop will address some of the challenges mentioned above both from the digital and RF point of view, combining commercial and defense perspectives with state-of-the-art research in the field. Experts from industry and academia that are at the frontline of these developments are invited to address these issues and inform the audience about the latest advances in this field.
