Enabling Advanced Devices With Atomic Layer Processes
By Katherine Derbyshire - 18 Apr, 2024 - Comments: 1

Atomic layer deposition (ALD) used to be considered too slow to be of practical use in semiconductor manufacturing, but it has emerged as a critical tool for both transistor and interconnect fabrication at the most advanced nodes. ALD can be speeded up somewhat, but the real shift is the rising value of precise composition and thickness control at the most advanced nodes, which makes the ext... » read more

Stretchy, sensitive circuits Researchers from Stanford University developed skin-like, stretchable integrated circuits capable of driving a micro-LED screen with a refresh rate of 60 Hz and detecting a braille array that is more sensitive than human fingertips. The stretchable transistors are made from semiconducting carbon nanotubes sandwiched between soft elastic electronic materials. The... » read more

Magnetic storage structures Researchers from The Ohio State University and Universidad Nacional Autonoma de Mexico investigated a new material that could potentially increase the capacity of magnetic storage devices. They identified manganese germanide, an unusual magnetic material in which the magnetism follows helices, similar to the structure of DNA. The structure gives rise to a number ... » read more

2D materials–based homogeneous transistor-memory architecture for neuromorphic hardware
By Technical Paper Link - 21 Aug, 2021 - Comments: 0

Abstract "In neuromorphic hardware, peripheral circuits and memories based on heterogeneous devices are generally physically separated. Thus exploring homogeneous devices for these components is an important issue for improving module integration and resistance matching. Inspired by ferroelectric proximity effect on two-dimensional materials, we present a tungsten diselenide-on-LiNbO3 cascaded... » read more

More speculative vulnerabilities Security researchers at the Graz University of Technology, KU Leuven, Cyberus Technology, and Worcester Polytechnic Institute point to two new speculative execution vulnerabilities related to Meltdown and Spectre. The first, which they dubbed ZombieLoad, uses a similar approach to Meltdown. After preparing tasks in parallel, the processor needs to discard th... » read more

Neural nets struggle with shape Cognitive psychologists at the University of California Los Angeles investigated how deep convolutional neural networks identify objects and found a big difference between the way these networks and humans perceive objects. In the first of a series of experiments, the researchers showed color images of animals and objects that had been altered to have a diffe... » read more
