  • Patent number: 8759183
    Abstract: A method of forming a semiconductor device may include forming a metal layer on a silicon portion of a substrate, and reacting the metal layer with the silicon portion to form a metal silicide. After reacting the metal layer, unreacted residue of the metal layer may be removed using an electrolyzed sulfuric acid solution. More particularly, a volume of sulfuric acid in the electrolyzed sulfuric acid solution may be in the range of about 70% to about 95% of the total volume of the electrolyzed sulfuric acid solution, a concentration of oxidant in the electrolyzed acid solution may be in the range of about 7 g/L to about 25 g/L, and a temperature of the electrolyzed sulfuric acid solution may be in the range of about 130 degrees C. to about 180 degrees C.

  • Patent number: 8207040
    Abstract: A method of manufacturing a semiconductor device includes forming a gate electrode on a semiconductor substrate and a sidewall spacer on the gate electrode. Then, a portion of the semiconductor substrate at both sides of the sidewall spacer is partially etched to form a trench. A SiGe mixed crystal layer is formed in the trench. A silicon layer is formed on the SiGe mixed crystal layer. A portion of the silicon layer is partially etched using an etching solution having different etching rates in accordance with a crystal direction of a face of the silicon layer to form a capping layer including a silicon facet having an (111) inclined face.

  • Patent number: 7709927
    Abstract: A semiconductor device includes a sidewall oxide layer covering an inner wall of a trench, a nitride liner on the sidewall oxide layer and a gap-fill insulating layer filling the trench on the nitride liner. A first impurity doped oxide layer is provided at edge regions of both end portions of the sidewall oxide layer so as to extend from an entry of the trench adjacent to an upper surface of the substrate to the nitride liner. A dent filling insulating layer is provided on the nitride liner in the trench to protect a surface of the first impurity doped oxide layer. Related methods are also disclosed.
