A conservative design approach which operates the devices well below the maximum current resulted in good circuit yield of 64% and repeatable operation at DC and at high frequency. Good agreement between measured and predicted performance was obtained, indicating that the design environment adequately represents the process.<<ETX>>","PeriodicalId":286222,"journal":{"name":"Proceedings of the 1992 Bipolar/BiCMOS Circuits and Technology Meeting","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132002686","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 divide-by-two module consists of a pair of master-slave flip-flops. A maximum clocking frequency of 2.5 GHz at a record low power of 1.7 mW per flip-flop has been realized.

The radiplanar process includes two process steps which are not used in conventional IC technologies. The first is high-energy, high-flux electron irradiation, and the second is pulsed laser treatment. A semi-insulating substrate is formed by irradiating a standard Si substrate with high-energy electrons to generate point lattice defects. Then only the surface of the irradiated substrate is made semiconductive by laser processing. Semiconductor devices are produced in the semiconductive regions of the substrate formed in this manner.<<ETX>>","PeriodicalId":286222,"journal":{"name":"Proceedings of the 1992 Bipolar/BiCMOS Circuits and Technology Meeting","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121854425","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}
