    Fan Out Packaging – Technology Overview and Evolution

    John Hunt John Hunt, ASE (US) Inc.
    8:30am–12:00pm | San Martin

    Mobile electronics has driven the need for ever increasing density and performance in electronics packaging. This has only accelerated with the advent of advanced smart phones and the burgeoning Internet of Things. This evolution has led to a need for higher levels of component density and functionality than has been traditionally available using standard packaging, resulting in a wide variety of new packaging options.

    We will review how the integration of wafer level processing technologies, substrate evolution and Flip Chip packaging structures have come together into what is being called Fan Out Packaging. These packages are for both low density and high density, Mobile and server applications. They have higher levels of integration and sophistication than has ever been possible in the past. These options include Wafer Level Fan Out, Panel Level Fan Out, and Chip Last Fan Out packaging. All of these can combine low cost materials and varied process flows to create both simple devices, and more complex System in Package and Package on Package applications. This course will provide an overview of the drivers, technology, advantages and disadvantages of various structural and processing options, as well as a view of potential future trends for Fan Out Packaging.

Emphasis is placed on various FOWLP assembly methods such as chip-first with die-up, chip-first with die-down, and chip-last (RDL-first). Since RDLs (redistribution layers) play an integral part of FOWLP, various RDL fabrication methods such as Cu damascene, polymer, and PCB (printed circuit board) will be discussed. A few notes and recommendations on wafer vs. panel, dielectric materials, and molding materials will be provided. Also, TSV-less interposers such as those given by Xilinx/SPIL, Amkor, SPIL/Xilinx, ASE, MediaTek, Intel, ITRI, Shinko, Cisco/eSilicon, Samsung, and Sony will also be discussed. Furthermore, new trends in semiconductor packaging will be presented.

    WS4

    Future of Packaging: Embedded and Non-embedded and Fan-out

    Prof. Rao Tummala Rao R. Tummala, Ph.D., Georgia Institute of Technology
    1:30pm-5:00pm | San Martin

    Semiconductor and systems landscape is changing dramatically. ICs, on one hand, for the most part, are becoming commodities, providing much lower profit margins than ever before, leading to industry consolidation to less than ten manufacturing companies within the next decade, worldwide. In addition, the cost and complexity of transistor scaling is growing exponentially. There is no longer a cost reduction as the next node is introduced with higher transistor density. In addition, IC performance is being greatly impacted by interconnect delay and leakage. The driving engines for electronic systems, on the other hand, are also changing dramatically to smart, wearable, wireless healthcare, wireless networks and new era of self-driving and electric cars, requiring an entirely different vision and strategy than transistor scaling alone that has been and continues to be practiced during the last 60 years. These systems are small to ultra-small systems and yet must perform dozens of functions that include high-speed digital, high-efficiency power, 5G and millimeter wave, MEMS and sensors.

    The new era of automotive electronics, in addition, requires a variety of sensing technologies for self-driving cars such as camera, LiDAR and radar, and ultra-high power for electric cars. All these emerging or next generation computing, communications, consumer and automotive systems pose device, packaging and integration barriers like never before. They require a new role for packaging. Unlike in the past, future packaging must add value in making better devices and better systems by addressing the device and system barriers by enabling better and cheaper devices and highly-integrated and ultra-miniaturized systems. The advances need to be more than Moore's (MTM) Law with on-chip transistor integration in 2D and 2.5D MCM, 3D stacked ICs with TSV and SIP. They require a new paradigms in systems packaging, referred to as “System Moore’s” Law (SM) for complete systems by a new and innovative 3D system concept. Such a new system package architecture concept goes beyond SIP, 2.5D and 3D with TSV. The course will review the current approach to devices, device packaging and system packaging. These include traditional single- and multi-chip packaging as well as the recent focus in embedded and fan-out packaging. This course sets the stage for new era in value-add packaging and new strategic technologies, manufacturing infrastructures and applications.

    Who Should Attend?
    Senior marketing and R&D executives as well as senior managers who are dealing with strategic issues facing the electronics industry should attend.
