A highly manufacturable I l0nm Embedded DRAM technology with stack A1,03 MIM capacitor has been demonstrated successfully for the first time. High-density DRAM core with 0.1pm2 cell size and high performance logic circuits have been realized at the same time by separation of the gate pattern at memory cell and peripheral logic region. Low temperature BDL process, highly reliable A124 MIM capacitors have been developed to control process temperature. DRAM cell performance has been improved by introducing tungsten wordline, CoSi, plug and tungsten bitline. 7 levels Cu and CVD-OSG low-k material have been implemented to satisfy the requirement of high performance logic circuits design.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
