These systems consist of a rail network and OHT vehicles. The components of the rail system are subject to high stress through vehicle motion. Individual fault-related failures in the rail network can cause considerable damage and loss of production. Therefore, it is necessary to reduce the fault probability to a minimum. For this reason, extensive preventive maintenance should be used with such a rail system. In preparation to change to a condition-based maintenance strategy, we developed a measuring platform for rail condition monitoring. This article describes the design of this platform and presents a first example of 3-D measurement data acquisition for spatial alignments checks.","PeriodicalId":262428,"journal":{"name":"2018 International Symposium on Semiconductor Manufacturing (ISSM)","volume":"53 3-4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123471837","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}

Due to the field-plate effect, it can improve tradeoff between low drift layer resistance and high breakdown voltage. In this structure, wafer warpage is larger than that of conventional structure. It causes various problems, for example an error in vacuum adsorption or wafer handling. We predicted the warpage change in a newly designed FP-MOSFET by TCAD simulation, and studied the reason of the warpage peculiar to FP-MOSFET. Moreover, we made a countermeasure in some critical process steps, and controlled the wafer warpage until the end of process.","PeriodicalId":262428,"journal":{"name":"2018 International Symposium on Semiconductor Manufacturing (ISSM)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127752513","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}
