This expansion is called vacuum photothermal processing (VPP). The treatment consists of a simultaneous irradiation of samples with electron flux and non-coherent light produced by a heated tungsten coil in vacuum. This paper presents studies of the influence of VPP on the interface between silicon substrates and metal coatings deposited on top of it was found that VPP provides for stabilizing the deposited coatings, improves homogeneity and curing the irreversible electrical breakdown in thin-film systems; it also improves the roughness of interfaces between semiconductor and metal coatings. These modifications and improvements are explained by the appearance of an intermediate layer which is made up while VPP and passivates the interface. This built-in layer, produced during VPP treatment, was discovered and is shown in this study","PeriodicalId":253409,"journal":{"name":"2005 13th International Conference on Advanced Thermal Processing of Semiconductors","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124337814","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 improved calibration procedure, which has been implemented in our NTM line of radiation thermometers, allows for more accurate wafer temperature measurement, particularly for very low emissivity wafers. The calibration procedure is improved by explicitly accounting for the localized drop in reflectivity of a calibration standard used for the reflectometer calibration, when this standard is brought in close proximity to the radiometer/reflectometer probe tip. The reflectivity of the standard decreases near the probe tip due to a small \"cavity effect\" interaction between the probe tip and the reflectivity standard. Failure to account for the decreased reflectivity of the calibration standard results in a small reflectometer calibration error, which causes the combined radiometer/reflectometer to exhibit a small residual emissivity dependence in the temperature measurement. The improved calibration procedure eliminates this small emissivity dependence, thus allowing improved temperature measurement accuracy, particularly for high reflectivity (low emissivity) wafers","PeriodicalId":253409,"journal":{"name":"2005 13th International Conference on Advanced Thermal Processing of Semiconductors","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129420524","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}

As device structures continue to shrink in geometry, integration of new materials and the complexity of process flows demand growth of high quality oxides with reduced thermal budget. This requirement poses a major challenge for thermal oxidation since lowering the process temperature causes degradation of oxide film quality, in general. Based on the fact that RadOxtrade have already demonstrated unique advantages in a variety of applications for current devices, it is expected that enabling radical oxidation at lower temperature would be beneficial for advanced devices. Highly concentrated ozone gas was employed as the source of radicals. The ozonator used for this study is capable to produce a gas mixture up to 90 vol% ozone (in oxygen) safely by adsorption/desorption technique. Several design of experiments (DOE) were carried out for thickness and thickness non-uniformity study, and film properties were compared with baseline processes using non-contact electrical measurements","PeriodicalId":253409,"journal":{"name":"2005 13th International Conference on Advanced Thermal Processing of Semiconductors","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132910713","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}
