Merged selective epitaxial growth of silicon was used to create local area SOI islands. Chemical-mechanical polishing was used to form well-controlled submicrometer-thick single-crystal SOI film using local area nitride as etch stops. Epitaxial lateral growth which was initiated from a vertical seed is demonstrated. The technique produces a generic full-wafer SOI structure. To obtain multiple layers of silicon over oxide, this SOI process can be repeated several times without damage to the previously formed layers and therefore makes three-dimensional integration possible.<<ETX>>","PeriodicalId":163406,"journal":{"name":"Proceedings Ninth Biennial University/Government/Industry Microelectronics Symposium","volume":"118 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120868115","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}

This resulted in a rapid drop of defect density and the correction of many systematic yield problems before full process lots were affected. The design of the test devices and the methodology is important to the success of the effort utilizing simple, statistically valid, large-scale arrays in the test chips, and a Pareto-driven, brutal focus analysis and improvement methodology.

Several measurement techniques including constant voltage, constant current, and voltage pulse were used. Consistent results have been obtained. time-dependent currents were observed in the low field region, i.e. less than 8 MV/cm for oxides thicker than 50 AA due to displacement currents and charge trapping. The slope of the Fowler-Nordheim plot is sensitive to the way the oxide field is estimated. For thicker oxides (greater than 100 AA), the slope may have a value between 240 approximately 300 MV/cm depending on the estimated oxide field. For thinner oxides, the slope is smaller due to the enhancement in the direct tunneling effect.<<ETX>>","PeriodicalId":163406,"journal":{"name":"Proceedings Ninth Biennial University/Government/Industry Microelectronics Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129450701","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 NMOS process described represents the first step toward the long-range goal of developing a CMOS technology. The design goals for the University of Florida NMOS (UF NMOS) process were to check the performance limits of the fabrication facilities and to develop a process flow which could be integrated into a one semester undergraduate laboratory. Processing capabilities include ion implantation and low-pressure chemical vapor deposition (LPCVD) of polysilicon and silicon dioxide. The availability of these processes allows design of an all-implanted technology including threshold-adjustment implants and polysilicon gates with a self-aligned MOS structure. The process description is given. Process design tools and layout tools are described. Testing procedures are outlined, and the laboratory implementation is discussed.
