The method has been demonstrated to be effective in measurements of p-n junctions from /spl sim/10 nm to >1 nm and over a dose range of /spl sim/10/sup 11/ to >10/sup 15/ ions/cm/sup 2/. RsL metrology is the first tool to provide dose metrology coverage over the full depth and dose range of CMOS transistor doping. The stability of the measurement results in an Rs repeatability for all junction conditions and does not require surface preparation, such as oxide strip, prior to measurement. RsL methods provide direct evaluation of junction leakage current, which is especially useful for shallow junction technology evaluation. The RsL probe has been incorporated into a fully-automated tool for in-line pilot line and production process development and production control applications.","PeriodicalId":307038,"journal":{"name":"Extended Abstracts of the Fifth International Workshop on Junction Technology","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114610339","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 formed NiGe film has an orthorhombic structure with dimensions comparable to that of bulk NiGe. With increasing the annealing temperature from 400 to 600/spl deg/C, the film surface roughness increases due to the increase of the grain size.

For this reason, the plasma doping method is considered to be promising compared to the conventional ion implantation, since it has significant advantages such as very high throughput and more compact in system hardware [2]-[6]. Formation of ultra-shallow p-type junction using boron is considerably difficult due to low energy requirement on doping and rapid diffusion of boron during thermal annealing that can increase junction depth. Very short time annealing such as flash lamp annealing (FLA) or spike rapid thermal annealing (RTA) is required to form such shallow junctions [7]-[ 10]. Fig. 1 is a plot of the R,-Xj relationship using the combination of the plasma doping and dopant activation process by FLA or spike RTA, which shows a successful formation of ultra-shallow junction [11][ 12]. However, the study on the leakage current across the ultra-shallow junction has been relatively limited. Since the impurity profile, the condition of amorphization, and the defect formation in the silicon wafers doped by the plasma doping are different from those by the conventional ion implantation, the characteristics ofthe residual defects after the activation annealing, to which the electrical characteristics of the junction is sensitive, might be different between the two.","PeriodicalId":307038,"journal":{"name":"Extended Abstracts of the Fifth International Workshop on Junction Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129582752","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}

To investigate the characteristic change of the photo-resist after ion implantation, the photo-resist removal performance is studied by FT-IR and SEM cross-section image analysis. The result shows that carbonization of photo-resist is promoted by the ion implantation. Both i-line photo-resist and KrF photo-resist were studied. The Si wafer was covered by the 400nm SiO/sub 2/ film. The surface potential measurement results of photoresist coating on SiO/sub 2/ film for various implantations were investigated. The results suggest that the destruction of the finer device due to charging at medium dose implantation will occur more frequently as the resolution of photo-resist is improved by lowering the bonding energy.","PeriodicalId":307038,"journal":{"name":"Extended Abstracts of the Fifth International Workshop on Junction Technology","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116302344","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}
