Disclosed herein is a method of manufacturing a semiconductor device having a step gate, which can improve the refresh characteristics of the device. The method comprises the steps of: forming on a silicon substrate having active and field regions a first hard mask exposing the field region; etching the exposed field region to form a trench; forming an isolation film by filling an insulating film in the trench; forming a second hard mask exposing both sides of the active region by etching the first hard mask; forming a metal film on the resulting substrate including the second hard mask; forming a metal silicide film on both sides of the active region by annealing the resulting substrate; removing the metal film unreacted in the annealing step and the metal silicide film, thereby recessing both sides of the active region; removing the second hard mask; and forming a step gate on both edges of the central portion of the active region and the recessed portion of the active region, adjacent to each of the edges.

The present invention relates to an antenna module which can minimize the occupying space in an electronic device, enhancing degrees of freedom to increase efficiency in space utilization, thereby accommodating miniaturization and multi-functionality of the electronic device, and an electronic device having the same. The antenna module includes a flexible substrate, an antenna element having a feeder part, a first fixing part, and a radiation part. The antenna module further includes a feeder line connected to the feeder part having a feeder pad, a first fixing pad connected to the first fixing part, and a pad coupling element. In the invention, signals are processed via interaction between the resonance of the current running through the feeder line to the radiation part and the resonance of the current coming into the pad coupling element.

A voltage level shifting circuit and method that can be used for shifting the voltage level of an input signal to provide an output signal having a higher output voltage level. The voltage level shifting circuit includes pull-up transistors that are switched OFF by the voltage of a pair of switching nodes and not the voltage at the output node. The speed at which the pull-up transistors can be switched OFF is decoupled to some extent from the speed at which the voltage at the output node changes. Additionally, having the output node separated from the nodes that switch the pull-up transistors OFF further allows for dimensions of the various transistors of the voltage level shifting circuit to be scaled advantageously.
