    摘要: An anode active material is provided. The anode active material includes a silicon thin film containing crystalline silicon having a Raman shift in a Raman spectrum ranging from about 490 to about 500 cm−1 and a full width at half maximum (FWHM) ranging from about 10 to about 30 cm−1. The volume of the anode active material does not change significantly during charging and discharging. Thus, a lithium battery employing the anode active material has an excellent capacity retention rate and a longer cycle lifetime.

    摘要: Methods of fabricating semiconductor devices include forming a transistor on and/or in a semiconductor substrate, wherein the transistor includes a source/drain region and a gate pattern disposed on a channel region adjacent the source/drain region. An insulating layer is formed on the transistor and patterned to expose the source/drain region. A semiconductor source layer is formed on the exposed source/drain region and on an adjacent portion of the insulating layer. A metal source layer is formed on the semiconductor source layer. Annealing, is performed to form a first metal-semiconductor compound region on the source/drain region and a second metal-semiconductor compound region on the adjacent portion of the insulating layer. The first metal-semiconductor compound region may be thicker than the second metal-semiconductor compound region. The metal source layer may include a metal layer and a metal nitride barrier layer.
