In this study, laser dicing, blade dicing and plasma dicing are first compared and plasma dicing is considered as the cleanest dicing method. Second, wafer surface protection by photoresist AZ4620 and a PDMS adhesion layer before wafer dicing is investigated. It is found that a thick protective layer mixing photoresist and PDMS together provides better protection effect, reducing particle density from 47.25 mm−2 to 19.71 mm−2. Then, surface protection of SiO2 by surface energy reduction is accomplished by spin-coating AR300-80-new and CF4 plasma treatment. The particle density shows a more significant decrease after CF4 plasma, owing to its greater effectiveness to lower dispersive component (<inline-formula> <tex-math>$gamma _{mathrm {sd}}$ </tex-math></inline-formula>) and the effect of increasing surface roughness. Finally, the particle density is further reduced by PDMS adhesion from 19.71 mm−2 to 7.60 mm−2. PDMS residue on the chip surface is detected by dynamic secondary ion mass spectroscopy (D-SIMS), and removed by O2 plasma treatment. The results provide feasible suggestions and approaches to decrease the deposition and adhesion of the particle generated from wafer dicing in C2W hybrid bonding.","PeriodicalId":451,"journal":{"name":"IEEE Transactions on Semiconductor Manufacturing","volume":"39 3","pages":"531-539"},"PeriodicalIF":2.5,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148694879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, the method introduces a strip convolution block to effectively suppress interference from background texture noise. Second, it integrates the content-aware attentional multi-scale aggregation module to recover high-resolution spatial details and reinforce feature semantic consistency and spatial localization capabilities. Moreover, the detection head is optimized by replacing the low-resolution P5 layer with a high-resolution P2 layer, which significantly enhances detection precision for extremely tiny targets. Finally, a task-oriented hybrid loss, termed Dynamic Angle-Inner IoU (DAI-IoU), is employed by combining SIoU, Inner-IoU, and Wise-IoU to improve bounding-box regression for slender micro-scratches.

This paper studies the applicability of adversarial variational autoencoders (VAE) as a practical sanitization mechanism for this setting. Sensitive process variables are specified by a domain expert, and the model is trained to preserve utility while making those variables harder to infer from the released representation. We evaluate the approach on native semiconductor manufacturing time-series runs, first in the original single-party setting and then in a small multi-peer extension with local and joint adversaries. The results suggest a privacy-utility trade-off: sanitized representations retain the main public operating regimes while degrading reconstruction of the protected variables. The distributed study further shows that leakage must be evaluated after aggregation, not only per peer. These results position adversarial VAE sanitization as a useful applied tool for semiconductor data sharing, while also highlighting the limitations of the current centralized simulation and small number of available runs.","PeriodicalId":451,"journal":{"name":"IEEE Transactions on Semiconductor Manufacturing","volume":"39 3","pages":"381-387"},"PeriodicalIF":2.5,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148694864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heating and cooling of the cleanroom and the equipment is a significant part of the energy demand. We have found opportunities to reduce the demand by carefully calibrated changes of two systems, the control of relative humidity (RH) in the cleanroom and the way in which we supply cooling water to the equipment. Varying these conditions can lower energy consumption and cost, but it can also affect the production process in a number of ways. To avoid adverse effects we established a list of potential issues and a plan to prevent any deviations. We then varied RH in a controlled fashion and verified that production can continue without issues. A similar approach was used to make a change to the cooling water supply. By equalizing the temperature between two separate systems used across tool platforms and then connecting these systems we gain efficiency, reduce complexity and save energy. As with the humidity change the challenge is to ensure there is no impact across all equipment affected by the change. We achieved a significant reduction of energy consumption through these changes.","PeriodicalId":451,"journal":{"name":"IEEE Transactions on Semiconductor Manufacturing","volume":"39 3","pages":"425-429"},"PeriodicalIF":2.5,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148695012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although prior studies have emphasized environmental considerations, they often lack actionable solutions aligned with fab-level operations. This paper advances the concept of the Sustainable Fab, articulated through three dimensions: environmental responsibility, cost efficiency, and optimized space utilization. Environmentally, we demonstrate practical reductions in utility consumption by implementing liquefied natural gas (LNG) flow control schemes and rationalizing hot N2 delivery without compromising process safety. For cost efficiency, we highlight strategies such as extending the lifespan of legacy vertical-NAND multilayered oxide/nitride layer deposition (MOLD) process tools through targeted retrofits and improving dual tank liquid refill (DTLR) systems to reduce unit counts, thereby lowering both capital investment and sub-fab infrastructure demand. From the perspective of space utilization, we introduce new density-based metrics—equipment station density (ESD) and facility station density (FSD)—to evaluate the transfer of productivity gains from tools to the fab level, and propose form factor–guided equipment designs to mitigate footprint mismatches. Collectively, these strategies provide an integrated framework that embeds sustainability into process, equipment, and facility domains, enabling scalable pathways for long-term competitiveness in semiconductor manufacturing.","PeriodicalId":451,"journal":{"name":"IEEE Transactions on Semiconductor Manufacturing","volume":"39 3","pages":"647-658"},"PeriodicalIF":2.5,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148695018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, current methods exhibit inherent limitations, including the cumbersome and time-consuming nature of finite element simulation techniques, as well as the difficulty of traditional machine learning methods in effectively learning physical laws during prediction, which may lead to results that contradict established physical principles. This paper proposes a physically constrained dual-channel neural network framework (PhyC-DCF), which aims to address the issue of prediction results contradicting physical principles by embedding physical prior knowledge, providing an efficient and accurate resonant frequency prediction tool for MEMS resonators. PhyC-DCF comprises a target resonant mode channel and an auxiliary resonant mode channel, which predict their respective resonant frequencies. The auxiliary channel integrates target features through resonant mode coupling mechanism, enabling complementary feature learning. Subsequently, a hybrid loss with physical constraints exploits resonator physics to guide training. The PhyC-DCF not only reduces error metrics but also effectively suppresses physically inconsistent phenomena such as frequency inversion, thereby providing an efficient and reliable computational tool for resonator design.","PeriodicalId":451,"journal":{"name":"IEEE Transactions on Semiconductor Manufacturing","volume":"39 3","pages":"636-646"},"PeriodicalIF":2.5,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148694774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although most deep learning models have been widely applied to this task, many still suffer from low accuracy and a high number of false alarms when dealing with class-imbalanced datasets. To address these issues, we propose a deep learning model based on dual-branch feature extraction and attention enhancement. This model consists of two parallel feature extraction branches. The first leverages a MetaDCNeXt architecture to capture spatial structural features of hotspots, while the second employs a multi-DenseConvSE architecture to extract semantic features through dense connections and channel attention. A positional convolutional block attention module is used to fuse the outputs from both branches, suppressing redundant information and emphasizing critical features. Experimental results on the ICCAD 2012 benchmark demonstrate that our model achieves the lowest average number of false alarms and the highest average F1 score, with its overall performance significantly surpassing all compared detectors.","PeriodicalId":451,"journal":{"name":"IEEE Transactions on Semiconductor Manufacturing","volume":"39 3","pages":"478-486"},"PeriodicalIF":2.5,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148694909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
