    Abstract: A first protective layer, a mask layer, a second protective layer and a photoresist layer are sequentially formed on a substrate. A photoresist pattern is formed by partially removing the photoresist layer. An ion implantation mask is formed by sequentially etching the second protective layer, the mask layer and the first protective layer using the photoresist pattern. The ion implantation mask exposes the substrate. Impurities are implanted in an upper portion of the substrate exposed by the ion implantation mask.

    Abstract: A method of fabricating a semiconductor device includes forming a gate pattern on a substrate, and etching sides of the gate pattern using a first wet-etching process to form a first recess. The first wet-etching process includes using an etchant containing a first chemical substance including a hydroxyl functional group (—OH) and a second chemical substance capable of oxidizing the substrate. The concentration of the second chemical substance is 1.5 times or less the concentration of the first chemical substance.
