摘要: A method of fabricating a semiconductor device includes performing pre-halo ion implantation on a semiconductor substrate, forming a first epitaxial layer over the entire upper surface of the semiconductor substrate, forming a second epitaxial layer over the entire surface of the first epitaxial layer, and forming a transistor at an active region of the second epitaxial layer. The first epitaxial layer prevents the ions implanted in the semiconductor substrate in the pre-halo implantation process from diffused into the second epitaxial layer under the effects of a process used to form the transistor.

摘要: A semiconductor device includes a substrate, a first region and a second region. Each of the first region and second region includes a trench, an epitaxial layer including a source/drain having a first part and a second part, the first part extending from a top surface of the substrate to a top surface of the source/drain and the second part extending from the top surface of the substrate to a bottom surface of the source/drain in the trench. The cross-sectional shape of the first part of the source/drain of the first region is the same as the cross-sectional shape of the first part of the source/drain of the second region. The cross-sectional shape of the second past of the source/drain of the find region is different from the cross-sectional shape of the second part of the source/drain of the second region.

摘要: In a method of forming an ohmic layer of a DRAM device, the metal silicide layer between the storage node contact plug and the lower electrode of a capacitor is formed as the ohmic layer by a first heat treatment under a first temperature and an instantaneous second heat treatment under a second temperature higher than the first temperature. Thus, the metal silicide layer has a thermo-stable crystal structure and little or no agglomeration occurs on the metal silicide layer in the high temperature process. Accordingly, the sheet resistance of the ohmic layer may not increase in spite of the subsequent high temperature process.
