As size reaches nanometric dimensions, changes in materials aim at performing a reliable and compliant technology with a maximum capability to reduce delay time and power consumption. At the 32 nm node, k value reduction of existing porous SiOCH and optimization of metallization with thin barrier, conformal seed and plating should mitigate RC and offer an improvement compared to current materials of the 45 nm node.","PeriodicalId":403602,"journal":{"name":"2007 IEEE International Interconnect Technology Conferencee","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115682659","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}

We compare two promising interconnects: carbon nanotube (CNT) and optical, with traditional Cu/low-K wires. We find that the optical wires yield the lowest latency and the highest bandwidth density. However, in terms of a system's top- down, novel, metric-bandwidth density per latency per power, CNTs can yield comparable performance to optical wires provided a certain mean free path and packing density is achieved. We quantify these technology parameters and also examine the impact of CNT diameter and bundle width on the performance comparison with Cu/low-K.","PeriodicalId":403602,"journal":{"name":"2007 IEEE International Interconnect Technology Conferencee","volume":"31 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130184110","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}
