Tutorial 1: Quantum computing technologies

Speaker: Maud Vinet (Leti)

Abstract:0

Thanks to superposition and entanglement, quantum computing is expected to extend the high performance computing roadmap at the condition of being able to operate a large number of qubits. First quantum reported quantum processors mostly rely on superconducting qubits. In comparison to other existing platforms such as photonic waveguides1, trapped ions2, and spin qubits3, the success of superconducting qubits can be attributed both to the fact that this technology is accessible by academic cleanrooms and that it benefits from advances in high-performance microwave instrumentation developed for telecommunication industry. On the other hand, Si-based QC appears as a promising approach to build a quantum processor; thanks to the size of the qubits, the quality of the quantum gates and the VLSI ability to fabricate billions of closely identical objects. And finally recently trapped ions and photonic based quantum processors have also attracted a lot of interest by being taken in charge by engineering teams with technologies that could be scaled up.

In this tutorial, we will start by a reminder on quantum computing principles and then we will identify the qubits figures of merit required to build a quantum processor. We will benchmark the experimental platforms and provide a system perspective on the challenges to reach high number of qubits, let’s say above 10,000.

Tutorial 2: Advanced Packaging Technologies for Heterogeneous Integration

Speaker: Ravi Mahajan and Sairam Agraharam (Intel)

Abstract:

Advanced packaging technologies are critical enablers of Heterogeneous Integration (HI) because of their importance as compact, power efficient platforms.  This tutorial will start by describing the role of advanced packaging in the overall HI landscape using the HI roadmap as a reference.  The tutorial will then describe the key physical and performance attributes of advanced packaging architectures and describe their evolution. Different packaging architectures will be compared primarily on the basis of their physical interconnect capabilities.  Key features in leading edge 2D and 3D technologies, such as EMIB, Silicon Interposer, Foveros and Co-EMIB will be described and a roadmap for their evolution will be presented.  This will be followed by a high-level discussion of Assembly and Test flows.  Challenges and opportunities in developing advanced package architectures will be discussed.  The scope of the discussion will include design for performance (i.e. ensuring efficient power delivery, high-speed signaling and thermal management), thermo-mechanical robustness, manufacturing considerations, materials and reliability. Reference will also be made to key enabling fields such as modeling, metrologies and equipment.  The tutorial will conclude with a discussion of overall opportunities and challenges in driving the advanced package roadmap forward.

Tutorial 3: Memory-Centric Computing Systems

Speaker: Onur Mutlu (ETH)

Abstract:

Computing is bottlenecked by data. Large amounts of application data overwhelm storage capability, communication capability, and computation capability of the modern machines we design today. As a result, many key applications’ performance, efficiency and scalability are bottlenecked by data movement. We describe three major shortcomings of modern architectures in terms of 1) dealing with data, 2) taking advantage of the vast amounts of data, and 3) exploiting different semantic properties of application data. We argue that an intelligent architecture should be designed to handle data well. We show that handling data well requires designing architectures based on three key principles: 1) data-centric, 2) data-driven, 3) data-aware. We give several examples for how to exploit each of these principles to design a much more efficient and high performance computing system. We will especially discuss recent research that aims to fundamentally reduce memory latency and energy, and practically enable computation close to data, with at least two promising novel directions: 1) performing massively-parallel bulk operations in memory by exploiting the analog operational properties of memory, with low-cost changes, 2) exploiting the logic layer in 3D-stacked memory technology in various ways to accelerate important data-intensive applications. We discuss how to enable adoption of such fundamentally more intelligent architectures, which we believe are key to efficiency, performance, and sustainability. We conclude with some guiding principles for future computing architecture and system designs.

Abstract:

The evolution of image sensors and the prospects utilizing advanced imaging technologies promise to improve our quality of life. Since CMOS image sensors have surpassed CCDs with the advent of column-parallel ADCs and back-illuminated technology, the image sensor application is expanding to mobile devices, wearables, medical solutions, security networks, factory automation and autonomous driving. Stacking technologies are now drastically accelerating the performance improvement and enhancing the functionality of imaging devices. The fine pitch connection between the pixel and logic layers makes the pixel parallel circuit architecture available for the next evolution. New materials for photoconductive layer extend the sensitivity to a wide range of wavelengths. This tutorial introduces a broad overview of the key device technologies for image sensors, as well as circuit techniques, image signal processing and performance characteristics, that enable imaging applications in various fields.

Tutorial 5: Innovative technology elements to enable CMOS scaling in 3nm and beyond – device architectures, parasitics and materials

Speaker: Myung-Hee Na (imec)

Abstract:

CMOS technology is crucial for the foundation of next-generation computing in various application domains. This fact fuels a strong technical appetite for further CMOS scaling down to 3nm and beyond.   However, this necessitates the development of new device architecture beyond FinFET in order to overcome the barrier of CMOS scaling as it exists now.

In this study, we will review a few key innovative device architectures such as Forksheet and CFET for next-generation CMOS device architectures.  We will share the results from device to block level performance to provide comprehensive views of new architectures.  However, it should be pointed out that innovative device architectures alone may not be sufficient to enable cell and block-level scaling. Since performance impact and routability of a block strongly depends on interconnects in advanced architectures, we believe the innovative interconnects should be simultaneously considered in combination with device architectures in sub-5nm node. As an example, we will provide a deep dive into smart power delivery with buried power rails and the optimization of power distribution networks .

Finally, we plan to discuss the challenges and opportunities of 2D materials for beyond SI channel for next-generation CMOS scaling.
