We examine the interconnect issues for both charge-based and spin-based information systems. For charge-based systems, since there are substantial activities in optical interconnect, this paper focuses on other concepts and approaches. Self-assembled molecular wires, carbon nanotubes/nanowires and virus engineered metallic wires can be used for interconnects. The use of new nano-architectures such as cellular automata, which use mostly nearest neighbors, make the use of self-assembled interconnects even more attractive. These techniques may be applied readily to molecular devices. Spin-based devices offer a new opportunity for low power, high functional throughput applications. We analyze the use of spin waves for information transmission buses referred to as spin wave bus. By introducing these novel circuits built on the spin-based devices and spin wave interconnect, we anticipate enhanced logic functionality. The challenges and issues are discussed.","PeriodicalId":156268,"journal":{"name":"Proceedings of the IEEE 2005 International Interconnect Technology Conference, 2005.","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128027463","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 proposed single step scheme is simpler than the currently existing airgap approaches.

As compared to the Cu/LK3.0 DD, the Cu/LK2.5 DD, processed using similar etching and ashing processes and chemistries, showed a 14% line-to-line (L-L) capacitance reduction at S=0.1 /spl mu/m. Other physical, electrical and reliability results show that the Cu/LK2.5 DD is comparable to the Cu/LK3.0 DD with no degradations commonly associated with conventional porous LK2.5s formed using porogens, such as peeling or LK recess in CMP, k increase or trench bottom roughening in patterning, high L-L leakage, low L-L Vbd or low SM resistance. Further process extendibility studies revealed that k<2.0 is also achievable using this quasi-porogen approach which strongly enables its applicability to current and future Cu/LK BEOL technologies.","PeriodicalId":156268,"journal":{"name":"Proceedings of the IEEE 2005 International Interconnect Technology Conference, 2005.","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124063890","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}
