Back-to-face wafer stacking using bumpless interconnects and ultra-thinning of wafers are key features used as alternatives to conventional micro-bumps and chip-based stacking technologies [2]-[6]. There is no need for a bump process involving solder bumps and Cu posts for die-to-die internal electronic connections. Ultra-thinning of wafers down to ~2 μm provides the advantage of a small form factor, not only in terms of the total volume of 3D ICs, but also the aspect ratio of through-silicon-vias (TSVs).","PeriodicalId":129300,"journal":{"name":"2016 IEEE Symposium on VLSI Technology","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134324475","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}

Using an accurate Lg = 30 nm FinFET model, L-K model parameters of ferroelectric (FE) layer are extracted from an experimental NC-FinFET data. With the experimentally calibrated model, we show for the first time that for the same inverter delay as the 14 nm ITRS FinFET, Vdd for NC-FinFET can be lowered from 0.7 V to 0.25 V, reducing energy by ~10×.
