| 摘要 |
There are provided a MOS transistor having a double gate and a manufacturing method thereof. The MOS transistor includes a substrate on which an insulating layer is formed, a first gate embedded in the insulating layer, in which the top surface of the first gate is exposed, a first gate oxide layer formed on the insulating layer and the first gate, a silicon layer formed on the first gate oxide layer, a source region and a drain region formed in the silicon layer to be in contact with the first gate oxide layer, a second gate oxide layer formed on the silicon layer to be in contact with the source and drain regions, and a second gate formed on the second gate oxide layer disposed between the source region and the drain region.
