Influence of Top Electrode Metal on Resistive Switching in Multilayer MOCVD MoS2 Memristors

Advanced Electronic Materials, EarlyView.
MoS2 memristors typically use evaporated noble metal electrodes. This study compares Pd, Ni, and Al electrodes and sputtered versus evaporated deposition. Pd is passive, while Ni damages MoS2, yielding poor switching. Sputtered Al enables reproducible ECM‐type switching with 95% yield, whereas evaporated Al forms an interfacial oxide that suppresses ...

Unraveling Etching Mechanism for SiN Film in Cryogenic Hydrogen-Fluoride Plasmas

Chemical Engineering Journal
Cryogenic plasma etching is a pivotal technology for next-generation 3D semiconductor devices with high-aspect-ratio and nanoscale features. During reactive ion etching of SiN in hydrogen fluoride (HF)-containing plasmas, an ammonium fluorosilicate (AFS) layer is formed; however, the precise role of the AFS in etching kinetic has remained highly ...
