The technology was designed to be integration-compatible with 1.3- mu m optical detectors. Integration levels ranged from 42 to 91 devices. For comparison, wafers were made with and without the optical detector epitaxial layers. High-speed performance with high yield has been achieved, showing that integration levels can be increased to realize more powerful optoelectronic circuit functions. Ring oscillator gate delays, with optical layers present, were as low as 61 ps at 16 mW/gate, and divide-by-2 operated to 1.6 GHz. Simulations show that optimized device sizing should significantly improve circuit performance. The high yield across four wafers indicates that complex OEICs are feasible.<<ETX>>","PeriodicalId":138960,"journal":{"name":"International Conference on Indium Phosphide and Related Materials","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124144392","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 calculations take into account the high-frequency dependence of the base noise current and the correlation of different currents contributing to the collector noise current. The high current gain and the excess noise observed in the input noise current could cause some limitations for low-level wideband applications. Scaling the emitter size is required to reduce the excess high-frequency noise. This can be done in the InP/InGaAs system without degrading its performance due to the low surface recombination velocity. Very high DC current gain could reduce the bandwidth where the noise remains low.<<ETX>>","PeriodicalId":138960,"journal":{"name":"International Conference on Indium Phosphide and Related Materials","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115739778","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}

High quality p/sup +/-n junctions on the order of 1 to 2 mu m are produced in a controllable manner at 500 degrees C.
