The equivalent oxide thickness (EOT) and leakage current were decreased by increasing deposition rate of HfO2 from 5.0 nm/min to 6.0 nm/min. The subthreshold swing (SS) of 107 mV/dec. and saturation mobility (μsat) of 150 cm2/(Vs) were obtained with deposition rate of 6.0 nm/min. Furthermore, the threshold voltage (VTH) was controllable as the number of identical erase pulse of 4 V/1 μs was increased, which suggested the VTH control of approximately 10 mV.","PeriodicalId":130513,"journal":{"name":"2022 International Symposium on Semiconductor Manufacturing (ISSM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130222370","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}

While this is true, it is certainly not the case where “more is better,” but rather an effort to define the truly necessary actions and best-known methods in maintaining tools to optimize availability, productivity, and product quality. The ongoing development and integration of Smart Manufacturing solutions across the factory systems landscape is now playing a role toward these objectives in providing a foundation for defining, deploying, and managing optimized maintenance task workflows. This paper will present both the efforts of companies using FabRecover, a novel maintenance management decision support framework, and the resulting demonstrable improvements that were achieved through such investments.","PeriodicalId":130513,"journal":{"name":"2022 International Symposium on Semiconductor Manufacturing (ISSM)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115029011","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}

Therefore, continuous data-driven yield monitoring and optimization provides opportunities to reduce production costs. Predicting yield during production would reveal its relationships with production parameters enabling dynamic optimization with a preventive and active increase in yield. In our investigations, we will first predict the yield based on one yield critical process step and later on with the data of four process steps. We will use different machine learning methods for this. Furthermore, we will look at whether the classification into good and bad yield values with these methods provides better results for the prediction. Another point of our investigations are the parameter limits of the individual methods. We show that these can be controlled by a simple method and optimised, if necessary.","PeriodicalId":130513,"journal":{"name":"2022 International Symposium on Semiconductor Manufacturing (ISSM)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132079450","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}

In this paper, the thickness uniformity of SiO2 insulating layer prepared on the inner wall of TSV based on CVD&PVD process and thermal oxidation method is comparatively studied. The experimental results show that, based on the CVD&PVD process, the average thickness of the SiO2 insulating layer at middle and bottom position of the TSV has changed by - 54.02% and - 58.30% compared with that at the top position, respectively. Based on the thermal oxidation method, the average thickness of the SiO2 insulating layer at middle and bottom position of the TSV has changed by 1.17% and 0.26% compared with that at the top position, respectively.
