ABSTRACT:
Provided are a DRAM semiconductor device and a method for fabricating the DRAM semiconductor device. The method provides forming a silicon epitaxial layer on a source/drain region of a cell region and a peripheral circuit region using selective epitaxial growth (SEG), thereby forming a raised active region. In addition, in the DRAM semiconductor device, a metal silicide layer and a metal pad are formed on the silicon epitaxial layer in the source/drain region of the cell region. By doing this, the DRAM device is capable of forming a source/drain region as a shallow junction region, reducing the occurrence of leakage current and lowering the contact resistance with the source/drain region.
