The APC technology improves the productivity of equipments based on two main control mechanisms: fault management and R2R (run-to-run) recipe correction. This paper focuses on FDC (fault detection and classification) for the fault management, and proposes a run-by-run process fault detection method. The method consists of a process event detection algorithm to segment process data, and a pattern matching technique to classify the segmented data as normal or abnormal state. Experiments using the data collected from a RIE (reactive ion etching) process show that the proposed method is able to recognize normal/abnormal states with high accuracy.","PeriodicalId":325607,"journal":{"name":"2007 International Symposium on Semiconductor Manufacturing","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130135997","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}

A thin layer (~15 nm) of nitride at the bottom of some SNC holes was intentionally created, EBI were performed at two stages: post etch clean and after silicon nitride cap of SNC plug. Negative mode EBI after SNC nitride cap deposition successfully captured these contact open defects as bright voltage contrast (BVC) defects. The cross-section scanning electron microscope (SEM) confirmed the results. The inspection mechanism is also discussed in the paper.

We evaluated a new particle control method that uses the repulsive electrostatic force to prevent the adhesion of particles.

By conducting field interviews and empirical study, this research summarizes three phases of inter-firm business models which include: transaction-based, partnership-based, and collaboration-based relationship. In the third phase, the participating partners include not only the foundry/fabless players but also the third-party suppliers such as EDA vendors, IP providers and design service providers. The transaction targets are exchanged mainly to gain \"complementary assets\" so that each player can reduce its investment and development risks. To reduce the \"transaction costs\" within this alliance, these players need seamless collaboration processes and effective inter-firm engineering processes. Service management from the foundry side is also described using a generic framework and some business implications are provided.","PeriodicalId":325607,"journal":{"name":"2007 International Symposium on Semiconductor Manufacturing","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114718568","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}
