A method of forming a semiconductor device is provided. The method includes preparing a substrate having a transistor region and an alignment region, forming a first trench and a second trench in the substrate of the transistor region and in the substrate of the alignment region, respectively, forming a drift region in the substrate of the transistor region, forming two third trenches respectively adjacent to two ends of the drift region, and forming an isolation pattern in the first trench, a buried dielectric pattern in the second trench, and dielectric patterns in the two third trenches, respectively. A depth of the first trench is less than a depth of the third trenches, and the depth of the first trench is equal or substantially equal to a depth of the second trench.

Semiconductor devices and methods of forming the same

A semiconductor device includes a body region of a first conductivity type and a gate pattern disposed on the body region. The gate pattern has a linear portion extending in a first direction and having a uniform width and a bending portion extending from one end of the linear portion. The portion of a channel region located beneath the bending portion constitutes a channel whose length is greater than the length of the channel constituted by the portion of the channel region located beneath the linear portion.

Semiconductor device

A semiconductor device comprises a device isolation pattern, an active region, a gate pattern, a first source/drain region, and a first barrier region. The device isolation pattern defines an active portion in a semiconductor substrate and the active portion comprises first and second sidewalls extending in a first direction and doped with a first conductive type dopant. The gate pattern extends in a second direction perpendicular to the first direction to cross over the active portion. The first source/drain region and the first barrier region are disposed in the active portion at one side of the gate pattern. The first barrier region is disposed between the first source/drain region and the first sidewall and contacts the first sidewall. The first barrier region is doped with the first conductive type dopant and the first source/drain region is doped with a second conductive type dopant.
