摘要

Semiconductor devices including a dummy gate structure on a fin are provided. A semiconductor device includes a fin protruding from a substrate. The semiconductor device includes a source/drain region in the fin, and a recess region of the fin that is between first and second portions of the source/drain region. Moreover, the semiconductor device includes a dummy gate structure overlapping the recess region, and a spacer that is on the fin and adjacent a sidewall of the dummy gate structure.

說明書

The controller 1110 may include at least one of a microprocessor, a digital signal processor, a microcontroller, and logic elements capable of functions similar to those of these elements. The I/O 1120 may include at least one of a keypad, a keyboard, a display device, and so on. The memory device 1130 may store data and/or commands. The interface 1140 may perform functions of transmitting data to a communication network or receiving data from the communication network. The interface 1140 may be wired or wireless. For example, the interface 1140 may include an antenna or a wired/wireless transceiver, and so on. The electronic system 1100 may further include high-speed DRAM and/or SRAM as a working memory for improving the operation of the controller 1110. The semiconductor devices 1 to 11 according to some embodiments of present inventive concepts may be provided in the memory device 1130 or may be provided as some components of the controller 1110 or the I/O 1120.

The electronic system 1100 may be applied to a personal digital assistant (PDA), a portable computer, a web tablet, a wireless phone, a mobile phone, a digital music player, a memory card, or any type of electronic device capable of transmitting and/or receiving information in a wireless environment.
