An HSG-Si layer is formed on a wafer under a uniform temperature condition. An apparatus for forming the HSG-Si layer includes a housing forming a process chamber, a first heater on which the wafer is positioned fixed in place at the bottom of the process chamber, a second heater at the top of the process chamber, and a thermal insulator which prevents the heat generated by the first heater from being transferred to the outside of the process chamber.
