Keynote 1

Topics in Nanopackaging

Plenary Session Summary:

We live in an Information Age driven by the astonishing progression of solid state electronics over the past 70 years since the invention of the transistor, and especially by the relentless march forward driven by industrial roadmaps based on faith in the infallibility of Moore’s Law. But even as Moore’s Law falters in the face of the challenges of nanoscale device manufacturing, new applications are opening up, e.g. flexible electronics, wearables, Internet of Things, quantum computing, etc. As IC chips became bigger and on-chip devices became smaller, electronics packaging, which has provided the chip with mechanical support, environmental protection, thermal dissipation, signal and power integrity, and system reliability from mainframe computers and PCs to smart phones, has kept pace through comparable innovations. Electronics packaging areas are becoming more specialized in meeting new environmental challenges, e.g. biomedical, oil well, space, aeronautics, and of that information center formerly known as an automobile! The current “grand challenges” for electronics packaging are 3D system integration by chip-stacking, embedded passives to provide more board real estate for active silicon, and the continuing battle against increasing power dissipation.

Nanotechnologies offer a variety of materials options for reliability improvements in microelectronics packaging, primarily in the applications of nanocomposites, or in the exploitation of the superior properties of carbon nanotubes and graphene. Nanoparticle composite materials are studied for resistors, high-k dielectrics, electrically conductive adhesives, conductive “inks,” underfill fillers, and solder enhancements, while nanowires, CNTs and graphene may also find thermal, interconnect, and shielding applications. The presentation will briefly cover electronics packaging as an introduction to nanopackaging, and then will emphasize some selected recent developments in the field, specifically:

  • Printed and sintered nanoparticle interconnects
  • Nanoparticle film sensors for electronics package reliability
  • Carbon nanotube (CNT) applications

and concluding with some relevant EHS (environment, health and safety) cautions.

Keynote 2

Recent advances in wireless charging

Plenary Session Summary:

The field of wireless power transfer (WPT) has been developing significantly. Wireless Power Transfer completely eliminates the existing high tension power transmission lines ,cables, and towers.Electric Vehicles (EV) have been proposed to achieve green transportation. Even though EV usage is currently increasing, a technology breakthrough would be required to overcome battery related drawbacks.

Wireless power transfer provides inherent electrical isolation and reduces on board charging cost, weight and volume. Nevertheless, WPT for EVs pose additional challenges and sustainability trade-offs and concerns that have stimulated discussion in academia and industry. In this presentation, we first review existing technologies for both stationary and dynamic charging of vehicles. We then propose a wireless power transfer technology using microwaves for the wireless charging of stationary EVs. It involves the design of a beam forming phased array antenna as a transmitter (TX) distributed on the parking walls or on garage walls that transmit power to the receiver antenna in the car. We use a phased array antenna technology to control and adjust the microwave power beam in order to increase efficiency and to reduce unexpected radiation outside of the receiving antenna. The harvested RF power is converted into DC supply to charge the battery while the EV parks over nightby using an appropriate rectenna circuit. This technology lends itself also to lower levels of power needed for wearable and IoT devices as will be demonstrated for applications in health care.
