Design criteria and guidelines, derived from experimentation and process/device simulation, are based on the following considerations: trench DRAM storage node capacitance, DRAM leakage mechanisms, retention time, n-well electrical parametrics, pnp bipolar current gain, latchup, and electrostatic discharge (ESD) performance. The methodology is discussed for achieving optimum power, signal, retention time, performance, reliability and ESD performance.<<ETX>>","PeriodicalId":287098,"journal":{"name":"1992 International Technical Digest on Electron Devices Meeting","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126842653","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 technology is named Tetraethylorthosilicate (TEOS) Ozone Pulse-wave Plasma Enhanced Chemical Vapor Deposition (TOP-PECVD). In the TOP-PECVD technology, TEOS-O/sub 3/ thermal film deposition and O/sub 2/+O/sub 3/ plasma film modification processes are alternately repeated in the same reaction chamber to obtain a thick and homogeneous film. The TOP-PECVD film has high conformality (Side/Top) of over 90%, which is much larger than that for a conventional TEOS-PECVD film (41%). On the other hand, it has less moisture content and smaller leakage current as compared to the conventional TEOS-PECVD film. Carbon content, measured by SIMS, is one hundredth times less than that in the TEOS-PECVD film. Delineation etching patterns show that the TOP-PECVD film has a good homogeneous quality.<<ETX>>","PeriodicalId":287098,"journal":{"name":"1992 International Technical Digest on Electron Devices Meeting","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116051956","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}

It was found that by reducing the concentration of the HF solution, the loss of thermal oxide and TEOS can be reduced almost to thicknesses which are equivalent to the native oxide thickness which has to be removed. To accelerate the reaction, higher temperatures can be used. In the case of poly-Si, it was found that the etching of the last monolayer of the native oxide is much slower than for monocrystalline Si. In the poly-Si case, this can be easily accelerated by the use of higher temperatures.<<ETX>>","PeriodicalId":287098,"journal":{"name":"1992 International Technical Digest on Electron Devices Meeting","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116271541","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}
