    • Embodiments relate to a method of manufacturing a CMOS image sensor in which, when a buried photodiode is formed, a p-type impurity region may be formed simultaneously with a p-type LDD region in the photo diode region. Additionally, a p-type impurity region may be formed under side wall spacers, which may reduce leakage current of the photodiode. In embodiments, the method may include providing a semiconductor substrate divided into a pMOS region, a nMOS region, and a diode region, forming a shallow trench isolation (STI) on the semiconductor substrate, opening only the nMOS region and implanting low density n-type impurities to form an n-type LDD region, opening the diode region and pMOS region and implanting impurities to form a p-type impurity region and a p-type LDD region, opening only the diode region and implanting impurities to form an n-type impurity region, forming side wall spacers on both side walls of the gate, opening only the nMOS region and implanting high density n-type impurities to form an n-type source and drain region, and opening only the pMOS region and implanting high density p-type impurities to form p-type source and drain region.
    • 实施例涉及制造CMOS图像传感器的方法,其中当形成掩埋光电二极管时,可以与光电二极管区域中的p型LDD区域同时形成p型杂质区域。 此外,可以在侧壁间隔物下形成p型杂质区,这可以减少光电二极管的漏电流。 在实施例中,该方法可以包括提供分成pMOS区域,nMOS区域和二极管区域的半导体衬底,在半导体衬底上形成浅沟槽隔离(STI),仅打开nMOS区域并注入低密度n- 形成n型LDD区域,打开二极管区域和pMOS区域并注入杂质以形成p型杂质区域和p型LDD区域,仅打开二极管区域并注入杂质以形成n型LDD区域, 在栅极的两个侧壁上形成侧壁间隔物,仅打开nMOS区域并且注入高密度的n型杂质以形成n型源极和漏极区域,并且仅打开pMOS区域并植入高密度 p型杂质形成p型源极和漏极区。

    • 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。
