High-Field Transport and Statistical Variability of Nanosheet Oxide Semiconductor FETs With Channel Length Scaling
No full textWe have investigated the scaling potential of nanosheet oxide semiconductor FETs (NS OS FETs) for monolithic 3-D (M3D) integration in terms of atomic layer deposition (ALD) material engineering, high-field transport, and statistical variability. We have developed and systematically compared InGaO (IGO), InZnO (IZO), and InGaZnO (IGZO) FETs by ALD. The effective mobility ( μeff ) characteristics of IGZO are higher than that of IGO and IZO at the same threshold voltage ( Vth ) in the normally-off region ( Vth>0 ). IGZO benefits from high μeff of IZO and low oxygen vacancy ( Vo ) of IGO and thus shows well-balanced characteristics. To study the carrier transport characteristics under a high electrical field, we have fabricated sub-100 nm gate length NS OS FETs and extracted transconductance ( gm ) as a metric. While bulk Si FETs show velocity saturation behavior even after parasitic correction, NS OS FETs show unsaturated velocity behavior. We also have obtained statistical variability data of NS OS FETs, which is comparable against bulk Si nFETs and Si SOI nFETs. This work provides evidence of the scalability of NS OS FETs for M3D integration.journal articl
NFT-Based System for Accurate Carbon Emission Tracking: Addressing Double Counting Issues in Supply Chain Management
No full textThis study introduces a system using Non-Fungible Tokens (NFTs) to track and report carbon emissions in supply chains accurately. It addresses the problem of double counting, which occurs when the same emissions are recorded multiple times due to product segmentation and integration. Our system uses blockchain technology to ensure NFTs are traceable and tamper-proof, enhancing data reliability. The system includes three types of NFTs: Parent NFTs (P-NFTs) for energy and raw material data, Child NFTs (C-NFTs) for manufacturing emissions, and Integration NFTs (I-NFTs) that compile the carbon footprint of final products. This method improves accurate emission tracking and transparency across the supply chain.conference pape
