A less void bonding interface was observed reveals a good bonding quality for the bonded samples. In addition, a large quasi-single grain was identified in the bondedfilm. Based on these results, it is believed that high strength and durable bonding structure can be accomplished by bonding two highly (111)-oriented nt-Cu films.","PeriodicalId":183993,"journal":{"name":"2017 5th International Workshop on Low Temperature Bonding for 3D Integration (LTB-3D)","volume":"166 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122149817","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 presence of CMOS circuitry with its limited thermal budget and the requirement of low pressures inside the microchamber impose strict requirements on the bonding process. We will describe metal-based approaches that leverage mature deposition and patterning techniques developed for integrated circuits (ICs) and micro-electro-mechanical systems (MEMS). The ability to produce finely patterned metal seals significantly reduces the real estate required for bonding and therefore lowers the size, weight, and cost of the device. In addition, massively parallel wafer-level processing drastically reduces the cost of the device. Metal-based approaches can be executed at low temperatures compatible with CMOS circuits and can be integrated with various substrate materials and topographies, making them ideal for smart sensors such as microbolometer FPAs.","PeriodicalId":183993,"journal":{"name":"2017 5th International Workshop on Low Temperature Bonding for 3D Integration (LTB-3D)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126833022","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}
