    摘要: A recessed gate electrode structure includes a first recess and a second recess in communication with the first recess both formed in a substrate. The second recess is larger than the first recess. A gate dielectric layer is formed on a top surface of the substrate and on an inner surface of the first and second recesses. A first polysilicon layer fills the first recess and is doped with impurities at a first impurity density. A second polysilicon layer fills the second recess and is doped with the impurities at a second impurity density. A void is defined within the second polysilicon layer. A third polysilicon layer is formed on the gate dielectric and first polysilicon layers and is doped with the impurities at a third impurity density. Due to impurities in the second polysilicon layer, migration of the void within the second recess may be substantially prevented.

    摘要: In a method of forming a layer having a lower electrical resistance and a method of manufacturing a semiconductor device, a first layer may be formed on a single crystalline substrate using amorphous silicon doped with impurities. A heat treatment may be performed on the single crystalline substrate at a temperature of about 550° C. to about 600° C. to convert the first layer into a second layer including a single crystalline silicon film transformed from a lower portion of the first layer contacting the single crystalline substrate and a polysilicon film transformed from an upper portion of the first layer. The layer may be formed at a relatively low temperature by a selective epitaxial growth process, and thus degradation or damage to a semiconductor device, which may be generated in a high temperature process, may be reduced.

    摘要: In a method for forming a gate electrode having an excellent sidewall profile, after a gate structure is formed on a substrate, a first oxide film is formed on a sidewall of the gate structure and on the substrate by re-oxidizing the gate structure and the substrate under an atmosphere including an oxygen gas and an inert gas. The gate structure has a gate oxide film pattern, a polysilicon film pattern and a metal silicide film pattern. A portion of the first oxide film formed on a sidewall of the polysilicon film pattern has a thickness substantially identical to that of a portion of the first oxide film formed on a sidewall of the metal silicide film pattern. A failure of a semiconductor device having the gate electrode can be minimized because the gate electrode has an improved sidewall profile.

    摘要: A method of fabricating a static random access memory device includes selectively removing an insulating film and growing a single crystalline silicon layer using selective epitaxy growth, the single crystalline silicon layer being grown in a portion from which the insulating film is removed; recessing the insulating film; and depositing an amorphous silicon layer on the single crystalline silicon layer and the insulating film, such that the amorphous silicon layer partially surrounds a top surface and side surfaces of the single crystalline silicon layer.
