    摘要: A method of forming an ion implantation mask includes forming a field area on a semiconductor substrate, forming an amorphous carbon layer on the semiconductor substrate, forming a hard mask layer on the amorphous carbon layer, forming an etching mask pattern on the hard mask layer, and etching the hard mask layer and the amorphous carbon layer to expose the field area through the etching mask pattern, wherein etching the hard mask layer and the amorphous carbon layer forms a hard mask layer pattern and an amorphous carbon layer pattern.

    摘要: A semiconductor device includes a gate structure formed on a substrate. The gate structure includes an uppermost first metal silicide layer pattern having a first thickness. Spacers are formed on sidewalls of the gate structure. One or more impurity regions are formed in the substrate adjacent to at least one sidewall of the gate structure. A second metal silicide layer pattern, having a second thickness thinner than the first thickness, is formed on the one or more impurity regions.

    摘要: An overlay mark may include a main overlay pattern and an auxiliary overlay pattern, wherein the main overlay pattern may have an opening exposing a substrate and the auxiliary overlay pattern may be formed in the opening. The auxiliary overlay pattern may be spaced apart from a sidewall of the main overlay pattern defining the opening. The thickness ratio of the auxiliary overlay pattern to the main overlay pattern may be about 0.05:1 to about 0.30:1. Accordingly, overlay accuracy measurements may be improved using the clearer overlay mark according to example embodiments.
