In our experiment, laser light of 633 nm wavelength is absorbed in the Si material through the generation of electron-hole pairs which, if generated in the depletion region, are separated by the high local field to give rise to a photocurrent that can be measured.<<ETX>>","PeriodicalId":308249,"journal":{"name":"Proceedings of 1993 IEEE International SOI Conference","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121160799","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 is mainly because SOI manufacturing yields have been considered to be lower than their conventional bulk counterparts. In spite of the recent development of fully depleted SOI devices fabricated in ultra-thin silicon on insulator films which are considered very attractive for high-speed submicron ULSI applications because of the reduced short-channel effect in addition to the generic SOI advantages of latchup immunity and reduced parasitic capacitances, several problems which should be overcome still remain, both in materials and device technology as well as in manufacturing aspects,before thin-film SOI can be considered mainstream. The major potential application for ultra-thin SOI films is quarter micron CMOS devices for advanced logic circuits. It is anticipated that CMOS devices having design rules of 0.25 /spl mu/m or less will be in mass production by the end of this century, and conventional bulk silicon seems to be unsuitable for such ULSI devices mainly because of severe short channel effects. Instead, thin-film SOI with fully depleted silicon films is expected to be an alternative.<<ETX>>","PeriodicalId":308249,"journal":{"name":"Proceedings of 1993 IEEE International SOI Conference","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126482863","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}

However, there is a lack of hot carrier information in SOS MOSFETs. SOS material differs from bulk material in that electron mobility is lower while hole mobility remains unchanged. Reduced mobility is not observed for holes because the mechanical strain in the epitaxial layer due to lattice mismatch between sapphire and silicon lifts the degenerate valence band significantly to make SOSFETs light hole devices. Since hot hole injection into the oxide is commonly observed in devices biased at low gate voltages, it is of great interest to study the contributions of light hole injection to device degradation mechanisms in both floating and non-floating body operation conditions. In this work, we will investigate the behavior of light holes at the oxide interface, and examine the effects of light hole injection under floating body operation on device degradation.<<ETX>>","PeriodicalId":308249,"journal":{"name":"Proceedings of 1993 IEEE International SOI Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122293298","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}

Continuous improvements in the quality of SIMOX materials has been demonstrated on a number of DoD programs, and a steady progression of devices from 16 K SRAM complexity to 1 M SRAM complexity have been produced. Even with the outstanding progress demonstrated in fabrication, the reliability of devices produced on SIMOX materials has not been extensively discussed. Of particular interest is the reliability effects of the SIMOX buried oxide, because of the unique processes used in its formation, and the previous identification of various types of defects which may be present. This paper presents reliability data on devices fabricated on SIMOX substrates, as reviewing on-going reliability evaluations of the SIMOX buried oxide itself. Data on circuit reliability testing at several rad-hard IC manufacturers are used to document the ability of SIMOX based devices to meet stringent military reliability qualification requirements. Evaluation of failures in the reliability testing show that the failure modes for SIMOX devices are much the same as for bulk devices. No new failure modes have been found that can be associated with the presence of the buried oxide.<<ETX>>","PeriodicalId":308249,"journal":{"name":"Proceedings of 1993 IEEE International SOI Conference","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122951669","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}
