Analog Computing Technologies and Circuits for Efficient Machine Learning Hardware

Organizer: Arindam Mallik (imec) and Nadine Collaert (imec)

The purpose of the workshop is to outline the challenges and novel solutions to implement analog computing for machine learning (ML) hardware. Deep Neural Networks (DNN) constitute the state-of-the-art in AI, from image processing to translation and speech recognition. Energy-efficient DNN is key to bringing these capabilities to edge devices. Analog in-Memory Computing (AiMC) using novel technologies such as RRAM, PCM, MRAM is gaining a large interest due to superb energy-efficiency. However, implementation of AiMC in a primarily digital system brings new challenges that range from device specifications to system architecture definition. The objective of this workshop is to share innovations at both technology and design space to enable system-technology co-optimization for ML hardware.

  • The workshop will provide a comprehensive and concise overview of the field of analog computing for ML.
  • Novel technology solutions (memory and logic devices) that are optimized for executing ML inference algorithm in the hardware.
  • Co-optimization of ML algorithm and system architecture to reduce the memory bottleneck and power consumption\
  • This workshop establishes the close interaction between the design and device technology community needed for optimal solution for ML hardware.

Know Where You Are Going; Metrology In the New Age of Semiconductor Manufacturing

Organizers: Tom Larson (Nova Measuring Instruments) and Gosia Jurczak (Lam Research)

Abstract: Measurement is at the forefront of every integration and process engineer’s daily life, whether for process control, development, yield ramping or failure analysis.  But understanding the basics of how the measurements are made, what technologies are deployed and what challenges remain is not universal.  This workshop will provide an outline overview from world class experts of the major technologies and approaches used now and looking into the future of inspection, process control and analysis.  The overview sessions will provide the attendee with an understanding of how measurement data is produced, how it is used and how measurements solve critical problems every day.  The agenda will span several talks from experts in the fab as well as experts from the fields of dimensional measurements, materials metrology, defect inspection and laboratory analysis including discussion around how machine learning is enhancing what we can extract from the data.  The organizers hope the attendees will leave the workshop with a more robust understanding of how their measurement data is created and perhaps with a better understanding of how to use the data.

The agenda will be 2.5 hours long.  It will start with an overview of challenges from logic and memory.  Then there will be a focal talk from each of the categories:  Inspection, Dimensional metrology, Materials metrology, Analytical Lab

Speakers and Presentations:

  • Tom Larson, Nova Measuring Instruments – “Introduction to Metrology Workshop”

  • Philippe Leray, imec – “Dimensional Metrology Overview, Trends and Upcoming Challenges”
  • Mark Shirey, KLA – “Defect Inspection: A Trio of Trends for the 2020s”
  • Kavita Shah, Nova Measuring Instruments – “Enabling Modern Semiconductor Manufacturing With Materials Metrology”
  • Markus Kuhn, Intel – “Opportunities and Challenges for Lab-based Characterization for Emerging Technologies”

Quantum Computing for Electrical Engineers

Organizer: Iuliana Radu (IMEC) and Maud Vinet (CEA Leti)

This workshop is going to outline the state of the art of quantum computing from material and integration to IC design and architecture and system. We will discuss and argue how quantum computing could be supported by our electrical engineering community and could provide a very aggressive path towards dedicated high performance computing problems. Through the workshop, we will try to provide a comprehensive and concise overview of the field of quantum computing enabled by VLSI technology.

The total duration of the workshop will be 2h30.
