摘要： In methods of selectively forming an epitaxial semiconductor layer on a single crystalline semiconductor and semiconductor devices fabricated using the same, a single crystalline epitaxial semiconductor layer and a non-single crystalline epitaxial semiconductor layer are formed on a single crystalline semiconductor and a non-single crystalline semiconductor pattern respectively, using a main semiconductor source gas and a main etching gas. The non-single crystalline epitaxial semiconductor layer is removed using a selective etching gas. The main gases and the selective etching gas are alternately and repeatedly supplied at least two times to selectively form an elevated single crystalline epitaxial semiconductor layer having a desired thickness only on the single crystalline semiconductor. The selective etching gas suppresses formation of an epitaxial semiconductor layer on the non-single crystalline semiconductor pattern.

摘要： Methods of fabricating a semiconductor device using a selective epitaxial growth technique include forming a recess in a semiconductor substrate. The substrate having the recess is loaded into a reaction chamber. A semiconductor source gas and a main etching gas are injected into the reaction chamber to selectively grow an epitaxial semiconductor layer on a sidewall and on a bottom surface of the recess. A selective etching gas is injected into the reaction chamber to selectively etch a fence of the epitaxial semiconductor layer which is adjacent to the sidewall of the recess and grown to a level that is higher than an upper surface of the semiconductor substrate.

摘要： A transistor includes a semiconductor substrate that has a first surface of a {100} crystal plane, a second surface of the {100} crystal plane having a height lower than that of the first surface, and a third surface of a {111} crystal plane connecting the first surface to the second surface. First heavily doped impurity regions are formed under the second surface. A gate structure is formed on the first surface. An epitaxial layer is formed on the second surface and the third surface. Second heavily doped impurity regions are formed at both sides of the gate structure. The second heavily doped impurity regions have side faces of the {111} crystal plane so that a short channel effect generated between the impurity regions may be prevented.

摘要： Methods of fabricating a MOS transistor having a fully silicided metal gate electrode are provided. The method includes forming an isolation layer in a predetermined region of a semiconductor substrate to define an active region. An insulated gate pattern which crosses over the active region is formed. A spacer is formed on sidewalls of the gate pattern. A selective epitaxial growth process is applied to form semiconductor layers on the gate pattern and on the active region at both sides of the gate pattern. In this case, a poly-crystalline semiconductor layer is formed on the gate pattern while single-crystalline semiconductor layers are concurrently formed on the active region at both sides of the gate pattern. The semiconductor layers are selectively etched to form a gate-reduced pattern and elevated source and drain regions. Respective desired thicknesses of the gate-reduced pattern and the elevated source and drain regions may be obtained using an etch selectivity between the poly-crystalline semiconductor layer and the single-crystalline semiconductor layer. A silicidation process is applied to the semiconductor substrate where the gate-reduced pattern is formed to simultaneously form a fully silicided metal gate electrode and elevated source and drain silicide layers.
