Abstract

In a method of manufacturing a semiconductor device, a tungsten layer pattern having an oxidized surface is formed on a substrate. A source gas including silicon is provided to the oxidized surface of the tungsten layer pattern to form a protecting layer on the oxidized surface of the tungsten layer pattern. The protecting layer prevents an abnormal growth of oxide contained in the oxidized surface. The protecting layer prevents a whisker from growing from the oxidized surface of the tungsten layer pattern.
