报告主要内容：

Internet-of-Things are becoming part of our everyday lives in consumer electronics as well as medical and avionics. IoT devices make up an information infrastructure; however, this infrastructure could be in danger due to cyber hardware uncertainties related to encryption, verification, Trojan hardware, and remote hacking. These uncertainties can lead to an unsafe regulatory environment, an unstable economy, increased cyber-security threats, and other major issues. Therefore, we need to protect the hardware from the circuit design phase to the manufacturing. However, the packaged IoT devices are difficult to protect against future Trojan virus due to their global design and manufacturing phases. Every IoT device has integrated Wi-Fi circuits. An integral RF component can also be realized using TSVs, thus reducing the footprint of the inductor on the die and making the inductance density per unit area much higher than that of the conventional 2D on-chip spiral inductors.

This seminar describes the design of through-silicon via (TSV)-based inductors for secure tunable Internet-of-Things (IoT). For a cybersecurity infrastructure, we designed 3D inductors with security hardware using physically unclonable function (PUF) circuit. The secure 3D inductor could be tuned to desirable frequency by using MEMS switches. Different fabrication techniques of 3D TSV inductors are provided to maintain high Q and inductance in high frequency.
