Course #1: Fan-Out Packaging and Chiplet Heterogeneous Integration

John H Lau, Unimicron Technology Corporation

Abstract: Fan-out wafer/panel-level packaging has been getting lots of tractions since TSMC used their integrated fan-out to package the application processor chipset for the iPhone 7. In this lecture, the following topics will be presented and discussed. Emphasis is placed on the fundamentals and latest developments of these areas in the past few years. Their future trends will also be explored. Chiplet is a chip design method and heterogeneous integration (HI) is a chip packaging method. HI uses packaging technology to integrate dissimilar chips, photonic devices, and/or components (either side-by-side, stacked, or both) with different sizes and functions, and from different fabless design houses, foundries, wafer sizes, and feature sizes into a system or subsystem on a common package substrate. These chips can be any kind of devices and don’t have to be chiplets. On the other hand, for chiplets, they have to use the heterogeneous integration to package them. For the next few years, we will see more implementations of a higher level of chiplet designs and HI packaging, whether it is for time-to-market, performance, form factor, power consumption or cost. In this lecture, the introduction, recent advances, and trends in chiplet design and HI packaging will be presented.

Abstract: The consumer electronics industry and today’s fast-growing automotive industry continue to demand ever-higher product hardware reliability. This tutorial will provide an overview of reliability testing methodology and statistical knowledge for qualifications of consumers and automotive electronic components. The reliability testing management includes various Rel testing methods and their application to product development at different phases will be first introduced. Some important statistic/probabilistic concepts including uncertainty, confidence level, and how to minimize/deal with them will be discussed. An effective approach to mitigate low sample size and short test duration will be introduced. Then the tutorial will focus on the physics of failure-based acceleration life models for some common reliability testing failures. A deep dive discussion on the temperature cycling model considering dT acceleration, dwell time acceleration, ramp rate acceleration, and Tmax acceleration will be explored. Next, a typical methodology to develop a PoF-based Rel validation testing plan reference to the product field mission profile will be introduced. The mission profiles of conventional vehicles and consumer smartphones will be compared. How to develop a customized mission profile for an autonomous vehicle specifically per its deployment location will be described. Finally, some examples of hardware failure modes with their risk assessments and lifetime modeling will be presented.

Course #4: Photonic Technologies for Communication, Sensing, and Displays

Torsten Wipiejewski, Huawei Technologies

Course Objective:

This course will provide an overview on the various photonic technologies that enable optical communication, optical sensing, and modern display applications. These applications are key for the information and communication technology of today and path a way to the future. High speed optical communication from board level in data centers to long haul transmission requires photonic components with high speed and high reliability. We will discuss the main components such as laser diodes of various types, high speed optical modulators and photodetectors as well as integration schemes such as photonic integrated circuits PICs and packaging aspects. Photonic technologies are also widely used as sensors for various applications including health monitoring. One key advantage is the potential for non-invasive measurements that facilitates the usage by end-users without specific medical knowledge. Packaging should provide high accuracy solution at low cost. Displays are the main media nowadays for bringing information to people. They range in size from smart watches to smart phones, laptops and tablets all the way to large screen TVs and video walls. We review current technologies and new developments such as quantum dots and micro LEDs as well as some features of 3D displays. In particular, micro LEDs for large size displays require novel assembly technologies to mount chips of only several micro meter in size with extremely high yield at very low cost. The mass transfer of thousands of chips simultaneously is an option to achieve this challenging target.   

Course Outline:

·       Fundamental properties of photonic components

·       Light sources (LEDs, laser diodes, others)

·       Transmitter and receiver components in optical communication (lasers, modulators, photodetectors, passive optical components, photonic integrated circuits PICs, silicon photonics, optical modules), monolithic and hybrid integration, packaging.

Course Objective:

The Heterogeneous Integration Roadmap (HIR) is a roadmap to the future of electronics identifying technology requirements and potential solutions, in a post-Moore world. The primary objective is to stimulate pre-competitive global collaboration between industry, academia and government to accelerate progress. The roadmap offers professionals, industry, academia and research institutes a comprehensive, strategic forecast of technology over the next 15 years. The HIR also delivers a 25-year projection for heterogeneous integration of Emerging Research Devices and Emerging Research Materials with longer research-and-development timelines. The HIR is sponsored by three IEEE Societies (Electronics Packaging Society, Electron Devices Society & Photonics Society) together with SEMI and ASME EPPD.  

This HIR Tutorial will deal with the near-term as well as far-term reliability challenges and needs faced by the six major application segments identified in the HIR Roadmap.  These include: (i) Aerospace and Defense; (ii) Automotive; (iii) High Performance Computing and Data Centers; (iv) Medical, Health and Wearables; (v) Mobile; (Vi) IoT.  The session will also present the phased vision and activities that are being formulated and proposed by the Reliability Technology Working Group in the HIR Team, as the pan-industry global approach needed to meet these reliability needs of the relevant stakeholders.  This vision will be presented in terms of goals and milestones for the short-horizon (1-5 years); mid-horizon (5—10 years) and far-horizon (10-15 years) time-scales.  The purposes for this HIR tutorial are to elicit audience interest, solicit voluntary participation from the community in the HIR activities & to stimulate collaboration among HIR stakeholders around the world.
