Research Bits: Feb. 6


Pillars for chiplet integration Researchers from the Tokyo Institute of Technology proposed a new chiplet integration technology called Pillar-Suspended Bridge (PSB), which they say is a simpler method of chip-to-chip connection compared to silicon interposers and redistribution layers. In the PSB, only a pillar-shaped metal structure called a "MicroPillar" is interposed at the connection b... » read more

ADC side-channel attacks Researchers at MIT propose two ways to protect analog-to-digital converters (ADCs) from power and electromagnetic side-channel attacks. The researchers first investigated the side-channel attacks that could be used against ADCs. Power attacks usually involve an attacker soldering a resistor onto the device’s circuit board to measure its power usage. An electromagn... » read more

Week In Review: Semiconductor Manufacturing, Test


This week saw more fallout from U.S. export controls: SK hynix may consider selling its memory chip production facilities in China if recently imposed controls make it too difficult to continue operations there, according to Nikkei Asia. "As a contingency plan, we are considering selling the fab, selling the equipment or transferring the equipment to South Korea," said Kevin Noh, SK hynix ... » read more

Research Bits: Oct. 25


Polarization for photonic processor Researchers from the University of Oxford and University of Exeter developed a photonic processor that uses multiple polarization channels, increasing information density. "We all know that the advantage of photonics over electronics is that light is faster and more functional over large bandwidths. So, our aim was to fully harness such advantages of phot... » read more

Using Reservoir Offset Voltage Of a Quantum Dot as Gate Electrode


Technical paper titled "The functions of a reservoir offset voltage applied to physically defined p-channel Si quantum dots" from researchers at Tokyo Institute of Technology and Device Technology Research Institute (D-Tech), National Institute of Advanced Industrial Science and Technology (AIST). Abstract "We propose and define a reservoir offset voltage as a voltage commonly applied to b... » read more

Review of Bumpless Build Cube Using Wafer-on-Wafer & Chip-on-Wafer for Tera-Scale 3D Integration


New research paper titled "Review of Bumpless Build Cube (BBCube) Using Wafer-on-Wafer (WOW) and Chip-on-Wafer (COW) for Tera-Scale Three-Dimensional Integration (3DI)" from researchers at Tokyo Institute of Technology and others. Abstract "Bumpless Build Cube (BBCube) using Wafer-on-Wafer (WOW) and Chip-on-Wafer (COW) for Tera-Scale Three-Dimensional Integration (3DI) is discussed. Bum... » read more

Usability of Authenticity Checks for Hardware Security Tokens


Abstract:  "The final responsibility to verify whether a newly purchased hardware security token (HST) is authentic and unmodified lies with the end user. However, recently reported attacks on such tokens suggest that users cannot take the security guarantees of their HSTs for granted, even despite widely deployed authenticity checks. We present the first comprehensive market review eva... » read more

Power/Performance Bits: Aug. 9


Capacitors in interposers Scientists at Tokyo Institute of Technology developed a 3D functional interposer containing an embedded capacitor. They tout the design as saving package area and reducing wiring length, resulting in less noise and power consumption. The capacitive elements are embedded inside a 300mm silicon piece using permanent adhesive and mold resin. The interconnects between ... » read more

Power/Performance Bits: Aug. 3


Efficient ADC Researchers at Brigham Young University, National Yang Ming Chiao Tung University, Texas Instruments, and University of California Los Angeles designed a new power-efficient high-speed analog-to-digital converter. The ADC consumes only 21 milli-Watts of power at 10GHz for ultra-wideband wireless communications, much lower than other ADCs that consume hundreds of milli-Watts to... » read more
