    • Disclosed are an apparatus and a method for controlling lamps which are provided in a dispenser and a backlight of a manipulation button array. According to the present invention, at least one lamp is provided in the dispenser and an illumination sensor for sensing the surrounding brightness of a refrigerator or a sensor for detecting a user approaching the refrigerator is also provided. There is also provided a memory unit for previously storing a reference luminous intensity, the value of which is capable of being changed by the user. There is also provided a lamp driving unit for selectively controlling the brightness of the lamp by controlling the output signal thereof according to a driving control signal of a control unit. According to the present invention, the user can easily take ice or water from the dispenser because the lamp is turned on. In addition, because the reference luminous intensity can be changed and stored in relation to the surrounding brightness of the refrigerator, it is possible to control the condition for turning on or off the lamp according to the surrounding environment or the user's taste. Moreover, because the dispenser and the backlight are normally illuminated with the minimum brightness, it is easy to use the dispenser, and because the dispenser and the backlight are illuminated with the maximum brightness for a predetermined length of time and then the illumination is gradually returned to the minimum brightness or turned off, it is possible to efficiently use the dispenser.
    • 公开了一种用于控制灯的装置和方法,其设置在操作按钮阵列的分配器和背光中。 根据本发明,在分配器中设置至少一个灯,并且还提供用于感测冰箱或用于检测接近冰箱的用户的传感器的周围亮度的照明传感器。 还提供了一种存储单元,用于预先存储参考发光强度,其值可由用户改变。 还提供了一种灯驱动单元,用于根据控制单元的驱动控制信号控制其输出信号来选择性地控制灯的亮度。 根据本发明,由于灯被打开,用户可以容易地从分配器中取出冰或水。 此外,由于可以相对于冰箱的周围亮度改变和存储参考发光强度,因此可以根据周围环境或用户的口味来控制打开或关闭灯的状态。 另外,由于分配器和背光通常以最小的亮度被照亮,因此容易使用分配器,并且由于分配器和背光源以最大亮度照亮预定的时间长度,然后照明逐渐返回 到最小亮度或关闭,可以有效地使用分配器。

    • A flash memory device includes a source region formed in an active region of a semiconductor substrate; a recessed region formed in the active region on either side of the source region, the recessed region including a recess surface having sidewalls; floating gates formed at the sidewalls of the recess surface by interposing a tunnel insulating film; a source line formed on the source region across the active region; and control gate electrodes formed at sidewalls of the source line across a portion of the active region where the floating gates are formed. The floating gates and the control gate electrodes are formed by anisotropically etching a conformal conductive film to have a spacer structure. Cell transistor size can be reduced by forming a deposition gate structure at both sides of the source line, and short channel effects can be minimized by forming the channel between the sidewalls of a recess surface.
    • 闪速存储器件包括形成在半导体衬底的有源区中的源区; 形成在所述源极区域的任一侧上的有源区域中的凹陷区域,所述凹陷区域包括具有侧壁的凹部表面; 通过插入隧道绝缘膜形成在凹槽表面的侧壁处的浮动栅极; 源极线,形成在源极区域上跨过有源区; 以及形成在源极线的侧壁的跨越形成有浮动栅极的有源区的一部分的控制栅电极。 浮置栅极和控制栅电极通过各向异性蚀刻共形导电膜以形成间隔结构而形成。 可以通过在源极线的两侧形成沉积栅极结构来减小晶体管尺寸,并且可以通过在凹陷表面的侧壁之间形成通道来最小化沟道效应。
