    摘要: A method of fabricating a semiconductor device is provided. First, a semiconductor substrate and a dielectric layer positioned on the semiconductor substrate are prepared. Subsequently, the dielectric layer is etched to form a hole structure in the dielectric layer. Afterward, a degas process is performed. An ultraviolet (UV) treatment is carried out to the semiconductor substrate in the degas process so as to expel at least a gas contained in the dielectric layer. Next, a barrier layer is formed on the sidewall and on the bottom of the hole structure. Furthermore, the hole structure is filled with a conductive material. Since the UV treatment can degas the dielectric layer efficiently, the formed semiconductor device can have a fine and stable structure.
