    • PURPOSE: A method for manufacturing a semiconductor device with a metal-semiconductor compound region is provided to reduce a contact resistance of source and drain regions of a transistor by forming a metal-semiconductor compound region using a semiconductor element source layer like a silicon layer formed on the source and drain regions of the transistor. CONSTITUTION: A semiconductor substrate(1) has a first device region(A) and a second device region(B). A first transistor(TR1) is formed on the first device region of the semiconductor substrate. The first transistor is formed on the upper sides of a first source and drain region and a channel region between the first source and drain regions. An insulation layer(27,30) is formed on the semiconductor substrate including the first transistor. A first opening(33a) exposes the part of the first source and drain region by patterning the insulation layer. A first semiconductor element source layer(42a,42b) is formed on the first source and drain region exposed by the first opening and the upper side of the insulation layer adjacent to the first opening unit. A metal device source layer(55a,55b,55c) is formed on the semiconductor substrate including the first semiconductor element source layer. First and second metal-semiconductor compound regions are formed with a silicide heat process. The first metal-semiconductor region is formed on the first source and drain regions. The second metal-semiconductor compound region is formed on the upper side of the insulation layer adjacent to the first opening.

    • A method for manufacturing a capacitor is provided to prevent damages on a lower dielectric film by patterning an upper electrode containing nickel silicide using a wet-etching process. An interlayer dielectric is formed on a substrate(100). A lower electrode pattern(130) containing a metal is formed on the interlayer dielectric. A dielectric film is formed on the interlayer dielectric and the lower electrode pattern. An upper electrode pattern(142) containing NiSi, is formed on the dielectric film. At least a portion of the upper electrode pattern is formed to be opposed to the lower electrode pattern. The upper electrode pattern is formed by forming a polysilicon film on the dielectric film. The polysilicon film is partially removed, such that the dielectric film is partially exposed. A polysilicon film is formed to be at least partially opposed to the lower electrode pattern. A nickel film is formed on the polysilicon pattern and the dielectric film. The NiSi pattern is formed by performing an RTP(Rapid Thermal Process) on the resultant material. The remaining nickel film is removed using a wet etching process.
    • 提供一种用于制造电容器的方法,以通过使用湿蚀刻工艺图案化含有硅化镍的上电极来防止对下电介质膜的损伤。 在基板(100)上形成层间电介质。 在层间电介质上形成含有金属的下电极图案(130)。 在层间电介质和下电极图案上形成电介质膜。 在电介质膜上形成含有NiSi的上部电极图案(142)。 上电极图案的至少一部分形成为与下电极图案相对。 上电极图案通过在电介质膜上形成多晶硅膜而形成。 部分去除多晶硅膜,使得电介质膜部分暴露。 多晶硅膜形成为至少部分地与下电极图案相对。 在多晶硅图案和电介质膜上形成镍膜。 通过对所得材料进行RTP(快速热处理)形成NiSi图案。 使用湿蚀刻工艺除去剩余的镍膜。
