In the meantime, also ultrathin SOI layers can be produced by wafer bonding and proper thinning techniques. In addition, silicon wafer bonding has shown to be a versatile technique for fabricating sensors and actuators. Especially in this area it is desirable to perform bonding at a temperature as low as possible. Wafer bonding may also be used to produce combinations of materials which may differ in terms of structure, crystallinity or lattice constant. The last feature allows the fabrication of III-V compound combinations which are not lattice matched and may be used for vertical cavity surface emitting lasers.","PeriodicalId":286176,"journal":{"name":"Proceedings of 4th International Conference on Solid-State and IC Technology","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126482857","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}

Microdisk lasers were fabricated by E-Beam direct writing combined with selective chemical etching processing. In addition, we successfully investigated an ICP dry etching system with a high density plasma and obtained a 0.4 /spl mu/m linewidth pattern. E-Beam doping is a new method to obtain 0.1 /spl mu/m shallow junction depth. We successfully apply the above technology and other alternative approaches for manufacture of 0.2 /spl mu/m Si MOSFET's, a 0.3 /spl mu/m PHEMT, a vacuum microelectronic diode array, etc. Adopted PECVD and Ar/sup +/ laser recrystallization technology combined with SiN/sub x/ barrier Si quantum micro crystals of nm size and photoluminescence were obtained.","PeriodicalId":286176,"journal":{"name":"Proceedings of 4th International Conference on Solid-State and IC Technology","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114149542","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}

A new method of Ultraviolet Fluorescence Spectra (UFS) measurements has been used to determine the contents of Fe on the surfaces of Fe-implanted samples. We find that the Fe-impurities have their own ultraviolet fluorescent peak wavelength at room temperature and their characteristic spectral peak intensities are proportional to the Fe-doses (Fe-concentrations) in Fe implanted Si samples. This method is very sensitive, efficient and nondestructive for testing the Fe contamination on silicon. Some SOI (Silicon on Insulator) wafers and VLSI chips were evaluated with the UFS method. The results indicate that the UFS method is able to measure the very low Fe-contamination. The limit is below (10/sup 8/-10/sup 9/) Fe/cm/sup 2/ or (10/sup 13/-10/sup 14/) Fe/cm/sup 3/ in Si samples.","PeriodicalId":286176,"journal":{"name":"Proceedings of 4th International Conference on Solid-State and IC Technology","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116058979","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}

Both tensile and compressive stress and Young's modulus of thin film can be derived by use of the V/sub PI/ method. In the LBD method, axial strain of beams can be converted into large transverse deflection which can be measured easily. These techniques have been analyzed, tested experimentally and comparison with other known stress measurement techniques show good consistency. Both techniques have been shown to be quite promising for simple and accurate on-chip thin-film stress measurements.","PeriodicalId":286176,"journal":{"name":"Proceedings of 4th International Conference on Solid-State and IC Technology","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116254353","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}
