Combination of the Principle Component Analysis (PCA) and the LASSO (least absolute shrinkage and selection operator) technique of the sparse modelling were introduced to define the multi-dimensional quality. Because the high accuracy and quick computations are required for the VM modelling, in this study, the PCA-LASSO combination was applied before building the VM models based on the kernel SVM (kSVM), particularly the linear kernel for real-time use. Those usefulness was evaluated by three different data sets; a CVD (Chemical vapor deposition) process in an actual semiconductor factory, an open-data of higher dimension which is measured in a chemical process, and a scalable data which is generated by using a multivariate normal random numbers based on the original CVD data. We will investigate versatility of the proposed method.","PeriodicalId":398770,"journal":{"name":"2019 Joint International Symposium on e-Manufacturing & Design Collaboration(eMDC) & Semiconductor Manufacturing (ISSM)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126040725","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 minimize chiller power consumption without affecting the environment of wafer production, optimizing chiller system operations become a crucial issue. Conventionally, chiller operations greatly depend on engineers' practical experiences. However, various uncertainties, including changeable weather and complicated chiller combinations, lead to inconsistent decisions of switching chiller machines as well as energy waste [1]. To improve the operational performance of the system for energy saving, researchers have proposed many different types of solutions, but those technologies are not easy to widely adopted in practical applications due to the complicated and limited operations and models.","PeriodicalId":398770,"journal":{"name":"2019 Joint International Symposium on e-Manufacturing & Design Collaboration(eMDC) & Semiconductor Manufacturing (ISSM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131096892","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 obtain high breakdown voltage and low on-resistance, trench field-plate (FP) MOSFETs have been continuously developed in recent years. It is necessary to design deep trench and thick field-plate oxide for higher breakdown voltage FP-MOSFETs [1]–[6]. In state-of-the-art FP-MOSFETs, as shown in Fig. 1, high cell density design has been developed for the purpose of getting low on-resistance. Fundamentally, it needs to shrink cell pitch, which consists of trench width and mesa width. Forming vertical trench is one method to realize narrow cell pitch. Voids are, however, generated in source field-plate polysilicon or gate poly-silicon in general [7]. If voids are gathered widely at the bottom of the source field-plate polysilicon (Fig. 1(a)), the effect of field-plate such as high breakdown voltage and good device characteristics cannot be obtained properly. Furthermore, if voids are formed at the bottom edge of the gate poly-silicon (Fig. 1(b)), effective gate bottom edge is underlapped with p-base. Thus, it is difficult to form the channel inversion layer at gate oxide interface. As a result, the on-resistance becomes increased. Therefore, suppressing void generation is one of the most significant process controls for trench FP-MOSFETs.","PeriodicalId":398770,"journal":{"name":"2019 Joint International Symposium on e-Manufacturing & Design Collaboration(eMDC) & Semiconductor Manufacturing (ISSM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124517337","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}
