发明名称 Memory device having buried source/drain region and fabrication thereof
摘要 A method of fabricating a memory device having a buried source/drain region is provided, in which a dielectric layer and a word-line is sequentially formed on the substrate, then a buried source/drain region is formed in the substrate. After that, a barrier layer is formed on the exposed surface of the word-line, then a metal layer is formed over the substrate. The metal layer is patterned to leave a portion covering the buried source/drain region beside the word-line and crossing over the word-line.
