摘要
This paper reviews the DRAM technology challenges for overcoming the 50nm barrier. First the product requirements and barriers to shrink the DRAM cell beyond 50nm will be addressed. Then the technology solutions for DRAM cell capacitor, cell transistor, and support transistors will be presented. Key enablers are high aspect ratio cell capacitor structures, new capacitor materials, 3-dimensional cell transistor schemes and high performance LSTP support device technologies.
