Abstract
A semiconductor structure includes a substrate, a trench, a first conductive layer, a second conductive layer, a third conductive layer, a source region and a drain region, a bit line contact, and a storage node contact. The trench is disposed in the substrate. The first conductive layer is disposed in the trench. The second conductive layer is disposed on a top surface of the first conductive layer. The third conductive layer is disposed on the top surface of the first conductive layer and is electrically connected to the second conductive layer. The source region and the drain region are disposed in the substrate and disposed on opposite sides of the first conductive layer. The bit line contact is disposed on one of the source region and the drain region, and the storage node contact is disposed on the other of the source region and the drain region.
