| 20110180868 | SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING THE SAME - The present invention relates to a semiconductor device and a method for manufacturing the same. According to the present invention, a method of manufacturing a semiconductor device includes: forming a recess on a semiconductor substrate; forming a first gate electrode material and a hard mask layer on an entire surface including the recess; etching the hard mask layer and the first gate electrode material to form the first gate electrode pattern on a lower portion of inside of the recess; forming a second gate electrode material on an entire surface including the recess; and etching the second gate electrode material and separating the second gate electrode material. | 07-28-2011 |
| 20110260242 | TRANSISTOR OF SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING THE SAME - Provided are a transistor of a semiconductor device and a method for manufacturing the same. A gate induced drain leakage (GIDL) current is reduced by decreasing a work function at an upper portion of a gate electrode, and a threshold voltage of the transistor is maintained by maintaining a work function at a lower portion of the gate electrode at a high level, thereby reducing a leakage current of the transistor and reducing a read time and a write time of the semiconductor device. The transistor of the semiconductor device includes: a recess with a predetermined depth in a semiconductor substrate; a first gate electrode disposed within the recess; and a second gate electrode disposed on the first gate electrode into which ions of one or more of nitrogen (N), oxygen (O), arsenic (As), aluminum (Al), and hydrogen (H) are doped. | 10-27-2011 |
