The role of packaging and system integration in future compute platforms
Michel, Bruno

IBM Research - Zurich

Liquid cooling enables computers as dense as a human brain. A universal concept is presented showing that volumetric density drives efficiency in information processing and can replace the currently slowing Moore’s law. By adopting some of the characteristics of the human brain, computers have the potential to become far more compact, efficient, and powerful so that we can take full advantage of cognitive computing and artificial intelligence. Bell’s Law shows that the progress in the information and telecommunication (ITC) industry is achieved in 12-15 year phases. Each new phase addresses a 10 times larger market, based on systems that are 100x denser, more efficient, and cheaper. A dense and efficient micro-server has been demonstrated as a first milestone along this roadmap. In addition more functionality is integrated with computing, most recently, in IoT and wearable devices, also sensing. This human centric sensing and computing provides contextual information that is key for relevant personalized cognitive services. Currently mobile are computationally strong enough to drive artificial intelligence at the edge instead of moving data to the cloud thus driving growth for cognitive cloud applications. The Internet of the Body (IoB) platform implements these concepts and can be adapted to many immediately useful use cases and test vehicles. The IoB platform connects wearables with edge and cloud computing to provide optimal user interaction and analytics on multi-stream data. This technology was applied to physiological and psychological stress classification using heart rate variability data in firemen training sites in Switzerland. We also introduced a home-based COPD management system to objectively track disease progress and coach actual patients into a better behavior. A hearable was developed for heat-stroke early detection and prevention based on monitoring of core body temperature and sweating which is planned to be tested with a Japanese national hospital.

Technology trend of flash memory and new memory
Susumu Yoshikawa

As flash memory increased its capacity it became one of important components in a Digital world and has been widely used in a lot of digital tools, such as Digital still camera, MP3 player, smart phone, SSD. In a recent years, Big data era is coming. New technologies such as IoT, AI and automated driving etc. have emerged and are becoming popular, these new technologies create, need and utilize huge amount of data. For example, IoT connects huge number of machine and collect data from these connected machine. AI analyze these data, and in order to improve accuracy, huge sample data are needed. To handle these huge data effectively, data storage system should have huge volume and high performance, and request to flash memory more capacity, high performance and low power. In this key note, recent key technologies such as 3D structure, QLC etc. and challenges for flash memory are discussed. And also topics of emerging memory are also introduced.

GPU: the Key Processor for AI and Supercomputing
Toru Baji
In the old good days, CPU performance increased almost 1.5 times / year thanks to the Moor’s Law. However around year 2010, due to the leakage current and too complex CPU architecture, this rate becomes 1.1 times / year. Today where Moor’s Law is at its end, the performance increase is almost 3% / year. On the other hand, parallel processing dedicated GPU continues to grow its performance with the rate of 1.5 times / year, and even with the Moor’s Law ending, it still continue to grow its performance by built-in accelerators. Pascal GPU came with Tensor Core which accelerates the AI matrix multiplication 12 times. And the latest Turing GPU further added a RT Core accelerator that increase the highest quality 3D computer graphics (ray tracing) more than 10 times.

GPU delivers around one to two order of magnitude performance advantage over the CPU and now is the most widely used processor in AI and Supercomputing. This GPU architecture is also applied to the most advanced autonomous driving SoC Xavier. An autonomous driving platform Pegasus with two Xavier SoCs and two discrete Turing GPUs are capable to realize the ultimate driver-less lever 5 autonomous driving.

In this talk, GPU basic technology which realize this high performance will be introduced. Also the implementation technologies including Si interposer packaging CoWoS, HBM2 3D-memory utilization and the breakthrough technology to overcome the die size limitation will be introduced.

Heterogeneous Integration on Fanout Packages
Shin-Puu Jeng
Taiwan Semiconductor Manufacturing Company,Ltd.
Significant technical advancement and business progress have been recently achieved in the area of advanced fanout package technology.
These packages exhibit excellent performance, power and form factor, which meets the ever increasing bandwidth demand, and unveils various important applications in intelligent mobile and HPC computation. Fine pitch Cu vias and traces enable heterogeneous integration of logic and memory, and allow fine power mesh, which reduces PDN impedance, improves power delivery, and reduces noise. The thin RDL structure increases thermal transfer efficiency. New multi-die chiplet fanout packages are possible alternatives to traditional chip scaling.
Multilayer 3D fanout stacking package exhibits both vertical and lateral integration flexibility. The heterogeneous integration with high bandwidth memory using fine pitch 2/2 um RDL lines further brings the fanout technology to a new height.

Printing in the Third Dimension;
Design, Materials, Equipment & Applications in Electronics

Charles E. Bauer, Ph.D.

Senior Managing Director
TechLead Corporation

Excitement around 3D printing continues full speed ahead whether in electronics, consumer goods or industrial systems. Understanding the capabilities, limitations and most importantly the complexities of 3d printing remains challenging despite significant progress in both equipment and materials. While not a comprehensive tutorial on 3D printing, this presentation introduces the application of 3D printing in electronics prototyping and manufacturing including;
  1. Types of 3d printing
  2. Design tools for 3d printed products
  3. Materials selection (availability and alternatives)
  4. Equipment choices
  5. Process capabilities and constraints
Specific examples include batteries, shielding, high density capacitors, and simple circuits. Discussion also includes applications outside the electronics world to stimulate creative thought, e.g. jet engine turbines and hyperbolic airfoils.
