Abstract:
Roll-to-roll (R2R) nanofabrication processes are recognized as key enabling-technologies for many next-generation applications in flexible electronics, displays, energy generation, storage, as well as healthcare. However, R2R processing techniques reported in the literature currently lack a scalable method of performing high-throughput nanoscale pattern transfer of geometry requiring a high degree of fidelity in terms of critical dimension resolution, etch uniformity, and aspect ratio. Reactive ion etching (RIE) addresses the need for sub-10 nm pattern transfer with large-area uniformity in wa

Abstract:
Here, we propose SnO2 as a reactive ion etching (RIE) mask in fluorine-based etching processes. Tin forms nonvolatile compounds with fluorine at the process temperatures enabling tin to function as an etch mask. We investigate atomic layer deposition (ALD) of SnO2 on silicon thermal oxide, silicon native oxide, H-terminated Si(001), and polystyrene surfaces using tetrakis(dimethylamino) tin(IV) and H2O at 170 °C to understand film nucleation patterns. Pinhole free films of approximately 1 nm thick SnO2 form on silicon thermal oxide and silicon native oxide and resist etching with SF6 under con

Abstract:
Abstract In this paper, we investigate inductively coupled plasma reactive ion etching of InP. The evolution of the surface/sidewall roughness and anisotropy is comparatively analyzed using different flow rates of CH4/H2, CH4/H2/Cl2, H2/Cl2 and Cl2 gases. In the study, RF bias power (P RIE) and inductive power (P ICP) were maintained at 150 W and 400 W, respectively. We have also reported results of the etched structures, including values of roughness average (Ra), inclination angle and etch rates using scanning electron microscopy and 3D profilometer images. Not only hydrocarbon chemistries (

Abstract:
Scaling semiconductor devices necessitates the fabrication of high-aspect-ratio narrow features through the precise etching of multiple layers comprising alternating materials, each with sub-20 nm thickness. However, etching dissimilar materials, such as alternating metal and oxide layers, pose significant challenges due to inherent discrepancies in vertical and lateral etch rates. This study demonstrates the feasibility of etching a stack comprising 10 layers of silicon dioxide (SiO2) and molybdenum (Mo) using an Oxford Instruments ICP RIE tool operating at a low power regime (bias < 2

Abstract:
AbstractManufacturing semiconductor devices requires advanced patterning technologies, including reactive ion etching (RIE) based on the synergistic interactions between ions and etch gas. However, these interactions weaken as devices continuously scale down to sub‐nanoscale, primarily attributed to the diminished transport of radicals and ions into the small features. This leads to a significant decrease in etch rate (ER). Here, a novel synergistic interaction involving ions, surface‐adsorbed chemistries, and materials at cryogenic temperatures is found to exhibit a significant increase in th

Abstract:
We propose shadow edge lithography (SEL) as a wafer-scale nanofabrication method. The shadow effect of “line-ofsight” in high-vacuum evaporation is analyzed theoretically to predict the geometric distributions of the fabricated nanoscale gaps. In the experiment, nanoscale gap patterns are created by the shadow of Al edges which are prepatterned using e-beam evaporation and the conventional ultraviolet lithography. Feasibility of the SEL is demonstrated by the fabrication of nanogaps having the width ranging from 15 to 100 nm on 4-inch Si wafers. Furthermore, by using the height differences in
