Manufacturing plants with high-mix low-volume types face the problem of having to create many quality prediction models with a small sample size. In this high-mix-low-volume-type plant, the construction of a highly efficient and accurate prediction model for product performance is an important issue. In this study, we propose a quality prediction model based on the hierarchical Bayesian model that can predict quality with high accuracy even for a small number of samples.","PeriodicalId":270309,"journal":{"name":"2020 International Symposium on Semiconductor Manufacturing (ISSM)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131816664","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}

After wet cleaning, it is difficult to determine the optimal number of seasoning wafers for the etch equipment. As a solution for this problem, the “Seasoning Index” that shows the progress of seasonings in the chamber is developed by using OES (Optical Emission Spectroscopy). Then, the Seasoning Optimizer function was implemented to make sure that the seasonings are performed appropriately. Furthermore, the principle of the seasoning process was also investigated. As a result, it was shown that the Seasoning Index, which shows similar behavior with the by-product of the reaction, is also effective as an index showing the seasoning state in the chamber. This case shows one of the application examples of AEC/APC.","PeriodicalId":270309,"journal":{"name":"2020 International Symposium on Semiconductor Manufacturing (ISSM)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124279835","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 order to quantify the metal concentrations, “re-dissolved method” in which the solvent is completely evaporated and re-dissolved in acid for analysis with an inductively coupled plasma mass spectrometer (ICP-MS), and “direct method” in which the solvent is directly introduced into the ICP-MS are evaluated. In both methods, it was found that impurities derived from the instruments used in the analysis affect the measurement, and it was possible to reduce metal elution from the instruments by performing appropriate pre-cleaning. In addition, the analysis accuracy could be ensured. As a result, we were able to measure the metal contained in IPA the lower limit of quantification of 1 ng/L by each method. Furthermore, it was confirmed that there was no difference in the analytical values between the both methods. By properly using the two methods, we believe that it can be widely applied to the analysis of organic solvents other than IPA and the analysis of multiple samples of a single solvent.","PeriodicalId":270309,"journal":{"name":"2020 International Symposium on Semiconductor Manufacturing (ISSM)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127698714","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}

Statistical process control (SPC) is known as a powerful method for accomplishing process stability and reducing variability. In this paper, we adopt the quality-oriented statistical process control (QOSPC) method. In QOSPC, product quality test data, such as electrical performance and product reliability, are incorporated in the process control procedure. QOSPC has two major challenges: extracting process variables that affect product quality, and determining quality control limits (QCLs) for each variable. In this work, we fully exploit a Bayesian approach to resolve both of these challenges simultaneously. We introduced a linear bathtub model (LBM) that contains parameters corresponding to QCLs as obvious change points and fit the model to the observed data by Bayesian inference (BI). In our experiments with artificial datasets, the values of QCLs and their probability of existence can be estimated robustly by BI. Using the proposed method, the human labor cost for determining QCLs is reduced by 93%.","PeriodicalId":270309,"journal":{"name":"2020 International Symposium on Semiconductor Manufacturing (ISSM)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126150249","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}
