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.

Who Should Attend?

If you (students, engineers, and managers) are involved with any aspect of the electronics industry, you should attend this course. It is equally suited for R&D professionals and scientists. The lectures are based on the publications by many distinguish authors and the books (by the lecturer) such as Fan-Out Wafer-Level Packaging (Springer, 2018), Heterogeneous Integration (Springer, 2019), and Semiconductor Advanced Packaging (Springer, 2021). Each attendee will receive more than 300 pages of lecture notes.

Course #2: Advanced Packaging for MEMS and Sensors

Horst Theuss, Infineon Technologies

Abstract: Sensors are everywhere! They create data and provide the “food” for the Internet of Things (IoT).  This course provides an overview on package approaches for MEMS- and sensor devices. Starting from standard semiconductor packaging, MEMS- and sensor specific challenges will be worked out. Case studies will make up a large part of the PDC, covering advanced packaging, such as Fan Out Wafer Level Packaging (FOWLP) but also mature leadframe and substrate-based concepts.

The discussion of MEMS packaging accounts for the major part of the course. MEMS involve mechanically movable or oscillating parts creating the need for cavity packaging. Various concepts for cavity packages will be discussed followed by an elaboration on package induced stress and its impact to MEMS performance. Case studies on pressure sensors and microphones include elaborations on package induced mechanical stress and its implications on device performance. This includes a discussion on package materials, their properties and function in the device. Within a short side trip we will evaluate options to assemble a MEMS-microphone chip into a FOWLP. Robustness requirements and approaches for risk mitigation in harsh environments represent a further topic of the PDC’s MEMS section.

A further section in the course covers RF-packaging for GHz applications making use of FOWLP. The discussion will include the capability of FOWLP with respect to RF-specific layouts but also briefly dig into concepts with antennas integrated into the package. Magnetic sensors and their implications to packaging represent the last application-specific section of the PDC.

The summary is intended to lead into a roadmap discussion about the future of MEMS and sensor packaging. Will the focus be on SiP (System in Package) or SoC (System on Chip)? What will be the future requirements before the background of IoT, heterogeneous integration and advanced packaging activities?

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.
