Certain new phenomena are observed in both the devices below 60 K which are attributed to carrier freezeout and high-level injection. These experimental results also tend to suggest that the useful range of operation of these devices can be extended to below liquid nitrogen temperature.<<ETX>>","PeriodicalId":302949,"journal":{"name":"Proceedings of the 1988 Bipolar Circuits and Technology Meeting,","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115748403","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}

These devices were used to characterize electrically the quality of the SEG material. Three silicon bipolar transistors with almost identical doping profiles and geometries were simultaneously fabricated on the same wafer and their electrical characteristics compared. The three transistors were located in the substrate, a single SEG layer, and a double (interrupted growth) SEG layer. The SEG silicon was grown in a reduced pressure, RF-heated, pancake-type epitaxial reactor at 950 degrees C and 150 torr. The transistors were tested for junction ideality factors, junction reverse bias leakage currents, and forward DC current gain. Test results showed average ideality factors, leakage currents, and gains were similar for all device types, indicating the excellent device quality of the SEG material relative to the substrate.<<ETX>>","PeriodicalId":302949,"journal":{"name":"Proceedings of the 1988 Bipolar Circuits and Technology Meeting,","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124835234","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}

It is shown that such models describe the static and dynamic input and output behavior of a gate completely. A main advantage of the introduced macromodel structure is the low number of network nodes. The example presented here shows the good coincidence of the macromodel with the reference values obtained by simulation of the whole gate. An extensive development is planned in the area of model building for tolerance behavior of gates with respect to V/sub cc/ and temperature influence. An application of the presented macromodel structure is planned for HCMOS and ACL technologies.<<ETX>>","PeriodicalId":302949,"journal":{"name":"Proceedings of the 1988 Bipolar Circuits and Technology Meeting,","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130092263","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}

It is shown to be a viable technique for the fabrication of advanced bipolar transistors. The use of amorphous instead of polycrystalline silicon as the emitter contact material results in a shallower emitter-base junction and little effect of the boron diffusion on the obtained arsenic profile. The narrowing of the base yields a higher intrinsic base resistance for the same number of carriers leading to a decrease in current gain for the same intrinsic base resistance. The different processing of double diffusion compared to base implantation may also lead to a loss in emitter efficiency. Nevertheless uniformity of the basewidth seems to be excellent and good high-frequency characteristics (up to f/sub T/=15 GHz) are obtained.<<ETX>>","PeriodicalId":302949,"journal":{"name":"Proceedings of the 1988 Bipolar Circuits and Technology Meeting,","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114668635","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}

Results show that for devices with a continuous interfacial layer the interface resistance controls the emitter resistance and is between 200 and 450 Omega mu m/sup 2/. This resistance is found to be current dependent and good agreement between theory and experiment is obtained. Results for devices with a discontinuous interfacial layer indicate that low interface resistances (17-33 Omega mu m/sup 2/) suitable for VLSI applications can be obtained by deliberately breaking up the interfacial layer. In this case the metal contact resistance contributes significantly to the total emitter resistance.<<ETX>>","PeriodicalId":302949,"journal":{"name":"Proceedings of the 1988 Bipolar Circuits and Technology Meeting,","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122265990","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}

Using this technology, a number of very high-speed ICs-a 18-GHz 1/8 divider, a 2-Gbsps 6-bit AD converter, and 43-ps/5.2-GHz macrocell array LSIs-have been developed.
