It is shown that the gate oxide damage by the plasma process can be monitored quantitatively by measuring the charge to breakdown Q/sub BD/. From Q/sub BD/ measurements, it is found that degradation occurs in the duration of over-etching, not in main etching. The breakdown spot in the gate oxide is detected by the photon emission method. The breakdown caused by plasma damage occurs at the local oxidation of silicon (LOCOS) edge. LOCOS structure plays an important role for the degradation by plasma damage.<<ETX>>","PeriodicalId":123048,"journal":{"name":"ICMTS 93 Proceedings of the 1993 International Conference on Microelectronic Test Structures","volume":"242 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123744013","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}

The models are based on a small set of measurable process characterization parameters, whose variation explains the range of performance seen during production. A statistical MOSFET model, based on these measurable process parameters, is developed using global optimization and regression modeling of key fitting parameters in order to accurately predict transistor characteristics over a wide range of process variation. These same process parameters can be measured on the manufacturing floor, both in-line and at electrical test, and can be used to predict the performance of the fabricated integrated circuit before packaging and final test. The models for use in manufacturing and design are integrated. Data taken from the manufacturing line can be used to identify process shifts, as well as to suggest design improvements for manufacturability enhancement.<<ETX>>","PeriodicalId":123048,"journal":{"name":"ICMTS 93 Proceedings of the 1993 International Conference on Microelectronic Test Structures","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130197141","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}
