| 摘要 |
A semiconductor device and a method for manufacturing the same are disclosed. A recess gate structure is formed between an overlapping region between a gate and a source/drain so as to suppress increase in gate induced drain leakage (GIDL), and a gate insulation film is more thickly deposited in a region having weak GIDL, thereby reducing GIDL and thus improving refresh characteristics due to leakage current.
