Molecular devices and methods of manufacturing the molecular device are provided. The molecular device may include a lower electrode on a substrate and a self-assembled monolayer on the lower electrode. After an upper electrode is formed on the self-assembled monolayer, the self-assembled monolayer may be removed to form a gap between the lower electrode and the upper electrode. A functional molecule having a functional group may be injected into the gap.

In semiconductor devices, and methods of formation thereof, both planar-type memory devices and vertically oriented thin body devices are formed on a common semiconductor layer. In a memory device, for example, it is desirable to have planar-type transistors in a peripheral region of the device, and vertically oriented thin body transistor devices in a cell region of the device. In this manner, the advantageous characteristics of each type of device can be applied to appropriate functions of the memory device.

Semiconductor devices include a semiconductor substrate with a stack structure protruding from the semiconductor substrate and surrounded by an isolation structure. The stack structure includes an active layer pattern and a gap-filling insulation layer between the semiconductor substrate and the active layer pattern. A gate electrode extends from the isolation structure around the stack structure. The gate electrode is configured to provide a support structure for the active layer pattern. The gate electrode may be a gate electrode of a silicon on insulator (SOI) device formed on the semiconductor wafer and the semiconductor device may further include a bulk silicon device formed on the semiconductor substrate in a region of the semiconductor substrate not including the gap-filing insulation layer.

Channels of two transistors are vertically formed on portions of two opposite side surfaces of one active region, and gate electrodes are vertically formed on a device isolation layer contacting the channels of the active region. A common bit line contact plug is formed in the central portions of the active region, two storage node contact plugs are formed on both sides of the bit line contact plug, and an insulating spacer is formed on a side surface of the bit line contact plug. A word line, a bit line, and a capacitor are sequentially stacked on the semiconductor substrate, like a conventional semiconductor memory device. Thus, effective space arrangement of a memory cell is possible such that a 4F2 structure is constituted, and a conventional line and contact forming process can be applied such that highly integrated semiconductor memory device is readily fabricated

A semiconductor device includes a semiconductor substrate having a recess therein. A gate insulator is disposed on the substrate in the recess. The device further includes a gate electrode including a first portion on the gate insulator in the recess and a second reduced-width portion extending from the first portion. A source/drain region is disposed in the substrate adjacent the recess. The recess may have a curved shape, e.g., may have hemispherical or ellipsoid shape. The source/drain region may include a lighter-doped portion adjoining the recess. Relate fabrication methods are also discussed.
