Precision at the Nanoscale: An Integrated Framework for Semiconductor Manufacturing, Device Design, and Circuit Implementation

Abstract

The advancement of semiconductor technology has reached a critical juncture where progress depends on the integration of understanding across multiple scales—from the plasma physics that governs etching processes, through the materials science that determines device performance, to the circuit design that determines system functionality. This article develops an integrated framework for semiconductor technology by examining four interconnected domains: the physics of electrokinetic waves and instabilities in solid-state plasma, the management of byproduct buildup in etch chambers, the design of plasma-enhanced sidewall passivation for RF and 5G devices, and the implementation of low-power digital circuits using gate diffusion input technology. Despite their apparent specialization, these domains share fundamental characteristics: they address phenomena that span multiple spatial and temporal scales, they require precise control of material and device properties at the nanoscale, and they increasingly rely on integrated approaches that bridge physics, materials science, and engineering design. The article argues that progress in semiconductor technology depends on recognizing these interconnections and adopting holistic approaches that address manufacturing, device, and circuit challenges simultaneously. It concludes by proposing a research agenda that emphasizes plasma process control, interface engineering, and the integration of physics-based and design-based methods.
