Conventional methods for characterizing these properties rely on direct electrical measurements, which are time-consuming and unsuitable for large-scale semiconductor production. This study presents an AI-based method that rapidly predicts the dielectric properties of HZO thin films from microscopic image data. A convolutional neural network (CNN) model was trained to infer dielectric behavior based on color changes induced by post-metal annealing (PMA) process conditions. These surface color variations are directly linked to internal structural phase transitions, supporting the use of optical features as indicators of dielectric phase states. The model achieved prediction accuracies of 63 % and 50 % when trained on image data from HZO and Mo regions in HZO thin-film capacitors, respectively. Using combined image data from both regions improved accuracy to 88 %, highlighting the significance of capturing both HZO crystal structure changes and Mo electrode oxidation effects. This AI-based inspection technique enables rapid, non-contact classification of dielectric properties at the chip level before the packaging process, offering a practical tool for early detection and process optimization in semiconductor manufacturing. In addition, this AI-based imaging inspection may work as a sensor module for the real-time feedback control system to achieve the targeted dielectric properties. While demonstrated on HZO, the approach can be extended to other thin-film materials where physical or chemical changes affect surface appearance, providing a scalable and cost-effective platform for inline quality control across various device fabrication processes.</div></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":"29 ","pages":"Article 100848"},"PeriodicalIF":8.7,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145044764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is particularly important for “real surfaces” which intrinsically exhibit heterogenous features that determines their behavior when interacting with biomolecules. Herein, we present a fresh perspective that focuses on probing local surface properties and dipeptide (Glu-Ala) binding on oxides grown on polycrystalline aluminum metal at the single-molecule level. First, a comprehensive surface characterization is performed to resolve the chemical composition and topography of two different native aluminum oxide surfaces. Then, by using atomic force microscopy (AFM) in force spectroscopy mode, we employ chemical force microscopy and colloidal probe techniques to quantify local surface charge and hydrophobicity, revealing noticeable differences between the two studied surfaces. Our findings demonstrate that both free enthalpies of adsorption (Δ<sub>ads</sub><em>G</em>°) and kinetic unbinding rates (<em>k</em><sub>off</sub>) are highly influenced by the surface characteristics probed locally, and suggest that the interaction of the dipeptide with the surfaces is dominated by van der Waals and hydrogen bonding. Beyond these fundamental insights regarding peptide–mineral interactions, this work provides methodological developments that are relevant for exploring molecular recognition mechanism, particularly on “real” oxide surfaces.

By performing high-throughput screening with various methodologies, we identified promising coating candidates such as LiTbO<sub>2</sub>, and LiDyO<sub>2</sub>, which exhibit inhibition of Li dendrite growth, non-reactivity, lithiophilicity, and sufficient ionic conductivity. Additionally, instead of directly synthesizing the coating layer from commercialized binary precursors, we experimentally induced the coating layers LiTbO<sub>2</sub> and LiDyO<sub>2</sub> from the binaries within the cell and validated their potential as coatings. Our findings provide a systematic framework for discovering and developing new materials to enhance the performance, safety, and commercial viability of all solid-state batteries.</div></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":"29 ","pages":"Article 100842"},"PeriodicalIF":8.7,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145019134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
