The substrates were obtained from 2 SIMOX suppliers (IBIS and SOITEC) and one bonded supplier (HDOS). Substrates were routinely obtained over a period of more than two years and this has given us some insight into the various manufacturers quality and reproducibility as well as improvement efforts. The material parameters such as film uniformity, contamination, defects, and wafer warp and bow will be discussed. In addition, the integrity of gate oxides grown on these substrates will be compared to those grown on bulk wafers. Device results such as threshold voltage control (Vt) and subthreshold leakage for devices built on SIMOX and BESOI wafers will be compared. These results have been obtained from several lots processed in our line and thus represent variations in both the material and the process.","PeriodicalId":149490,"journal":{"name":"1995 IEEE International SOI Conference Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1995-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123945623","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}

In order to meet the requirements regarding reliability, low area consumption and flexibility the dielectric isolation is superior to the other isolation techniques such as self isolation or junction isolation. Integrated power devices on fully isolated SOI wafers showed the advantages of bonded SOI material for this application. However, the full isolation restricts the power devices to area consuming lateral devices or up-drain DMOS type devices only suitable for medium power applications. Devices with high current and high breakdown voltage capability require vertical transistor types. So far, different attempts have been made to integrate vertical connected and dielectrically isolated areas on one wafer. We have developed a process, which allows the fabrication of vertical connected areas and device isolation before bonding and requires no special alignment. First, the area for the vertical contact is patterned and covered with a silicon nitride layer. Subsequently, V-grooves are patterned, etched and thermally oxidised. After removal of the nitride layer the V-grooves are filled with polysilicon. Depending on the deposition conditions, the vertical contact area is filled with polysilicon or epitaxial grown silicon. Thinning occurs by chemo-mechanical polishing. As in the \"classical\" DI process the oxide at the bottom of the V-groove serves as a polishing stop resulting in a better SOI thickness uniformity.","PeriodicalId":149490,"journal":{"name":"1995 IEEE International SOI Conference Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1995-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122701974","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 dramatically different behavior for SOI implies that the antenna design rule requirements for bulk and SOI MOSFETs will not be the same.
