摘要:
Semiconductor devices may include a gate pattern and a contact pattern disposed on an active region. The contact pattern may include a recessed portion near the gate pattern, and a rising portion away from the gate pattern. The gate pattern may include a gate insulating layer and a gate electrode disposed on the gate insulating layer. An upper surface of the recessed portion may be lower than an upper surface of the rising portion.

A robot refrigerator and a robot refrigerator system are provided. The robot refrigerator is remotely controlled. The robot refrigerator generates image information from a surrounding image and transmits the generated image information to a wireless communication device. The wireless communication device remotely controls the robot refrigerator, or monitors or remotely controls the robot refrigerator in real time, so that the robot refrigerator easily avoids an obstacle, and thus, minimizes a movement time of the robot refrigerator. Thus, user convenience and system reliability is improved.

Semiconductor devices including a first transistor and a second transistor are integrated on a substrate. Each of the first and second transistors include a nano-sized active region including source and drain regions provided in respective end portions of the nano-sized active region and a channel forming region provided between the source and drain regions. The source and drain regions of the first transistor have the same conductivity type as those of the second transistor, and the second transistor has a threshold voltage lower than that of the first transistor. The channel forming region of the second transistor may include a homogeneously doped region, whose conductivity type is the same as the source and drain regions of the second transistor and is different from the channel forming region of the first transistor.

Disclosed are a robot refrigerator and a robot refrigerator system. The robot refrigerator can be remotely controlled. The robot refrigerator generates image information from a surrounding image and transmits the generated image information to a wireless communication device. Then, the wireless communication device remotely controls the robot refrigerator, or monitors or remotely controls the robot refrigerator in real time, so that the robot refrigerator can easily avoid an obstacle to thus minimize a movement time of the robot refrigerator. Thus, user convenience and system reliability can be improved.

A semiconductor memory device performing an erase operation using an erase gate and a method of manufacturing the same are provided. The memory device may include a charge trap layer storing a first charge transfer medium having a first polarity and at least one erase gate. The at least one erase gate may be formed below the charge trap layer. A second charge transfer medium, which has a second polarity opposite to the first polarity, may be stored in the at least one erase gate. During the erase operation, the second charge transfer medium migrates to the charge trap layer causing the first charge transfer medium to combine with the second charge transfer medium.
