Improved Performance of GaN-Based Ultraviolet LEDs with the Stair-like Si-Doping n-GaN Structure
By Technical Paper Link - 06 Oct, 2021 - Comments: 0

Abstract "A method to improve the performance of ultraviolet light-emitting diodes (UV-LEDs) with stair-like Si-doping GaN layer is investigated. The high-resolution X-ray diffraction shows that the UV-LED with stair-like Si-doping GaN layer possesses better quality and a lower dislocation density. In addition, the experimental results demonstrate that light output power and wall plug effici... » read more

High-NA EUVL: the next major step in lithography
By Technical Paper Link - 05 Oct, 2021 - Comments: 0

"In the course of 2025, we expect to see the introduction of the first high-NA extreme ultraviolet (EUV) lithography equipment in high-volume manufacturing environments. These next-generation lithography systems will be key to advance Moore’s Law towards the logic 2nm technology generation and beyond. In this article, imec scientists and engineers involved in preparing this major engine... » read more

Modeling electrical conduction in resistive-switching memory through machine learning
By Technical Paper Link - 04 Oct, 2021 - Comments: 0

Published in AIP Advances on July 13, 2021. Read the full paper (open access). Abstract Traditional physical-based models have generally been used to model the resistive-switching behavior of resistive-switching memory (RSM). Recently, vacancy-based conduction-filament (CF) growth models have been used to model device characteristics of a wide range of RSM devices. However, few have focused o... » read more

Inverse lithography technology: 30 years from concept to practical, full-chip reality
By Technical Paper Link - 01 Oct, 2021 - Comments: 0

Published in the Journal of Micro/Nanopatterning, Materials, and Metrology, Aug. 31, 2021. Read the full technical paper here (open access). Abstract In lithography, optical proximity and process bias/effects need to be corrected to achieve the best wafer print. Efforts to correct for these effects started with a simple bias, adding a hammer head in line-ends to prevent line-end shortening. T... » read more

PTAuth: Temporal Memory Safety via Robust Points-to Authentication
By Technical Paper Link - 08 Sep, 2021 - Comments: 0

Authors: Reza Mirzazade Farkhani, Mansour Ahmadi, and Long Lu, Northeastern University Abstract: "Temporal memory corruptions are commonly exploited software vulnerabilities that can lead to powerful attacks. Despite significant progress made by decades of research on mitigation techniques, existing countermeasures fall short due to either limited coverage or overly high overhead. Further... » read more

Database Reconstruction from Noisy Volumes: A Cache Side-Channel Attack on SQLite
By Technical Paper Link - 08 Sep, 2021 - Comments: 0

Authors: Aria Shahverdi, University of Maryland; Mahammad Shirinov, Bilkent University; Dana Dachman-Soled, University of Maryland Abstract: "We demonstrate the feasibility of database reconstruction under a cache side-channel attack on SQLite. Specifically, we present a Flush+Reload attack on SQLite that obtains approximate (or "noisy") volumes of range queries made to a private database... » read more

SMASH: Synchronized Many-sided Rowhammer Attacks from JavaScript
By Technical Paper Link - 08 Sep, 2021 - Comments: 0

Authors: Finn de Ridder, ETH Zurich and VU Amsterdam; Pietro Frigo, Emanuele Vannacci, Herbert Bos, and Cristiano Giuffrida, VU Amsterdam; Kaveh Razavi, ETH Zurich Abstract: "Despite their in-DRAM Target Row Refresh (TRR) mitigations, some of the most recent DDR4 modules are still vulnerable to many-sided Rowhammer bit flips. While these bit flips are exploitable from native code, tri... » read more

Automatic Extraction of Secrets from the Transistor Jungle using Laser-Assisted Side-Channel Attacks
By Technical Paper Link - 08 Sep, 2021 - Comments: 0

Abstract:  "The security of modern electronic devices relies on secret keys stored on secure hardware modules as the root-of-trust (RoT). Extracting those keys would break the security of the entire system. As shown before, sophisticated side-channel analysis (SCA) attacks, using chip failure analysis (FA) techniques, can extract data from on-chip memory cells. However, since the chip's... » read more

On the Design and Misuse of Microcoded (Embedded) Processors — A Cautionary Note
By Technical Paper Link - 08 Sep, 2021 - Comments: 0

Abstract:  "Today's microprocessors often rely on microcode updates to address issues such as security or functional patches. Unfortunately, microcode update flexibility opens up new attack vectors through malicious microcode alterations. Such attacks share many features with hardware Trojans and have similar devastating consequences for system security. However, due to microcode's opaq... » read more

Usability of Authenticity Checks for Hardware Security Tokens
By Technical Paper Link - 08 Sep, 2021 - Comments: 0

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
