    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: A semiconductor device with improved transistor operating and flicker noise characteristics includes a substrate, an analog NMOS transistor and a compressively-strained-channel analog PMOS transistor disposed on the substrate. The device also includes a first etch stop liner (ESL) and a second ESL which respectively cover the NMOS transistor and the PMOS transistor. The relative measurement of flicker noise power of the NMOS and PMOS transistors to flicker noise power of reference unstrained-channel analog NMOS and PMOS transistors at a frequency of 500 Hz is less than 1.

    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: 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.
