Abstract: PURPOSE: A method of forming a low permittivity interlayer dielectric is to form the interlayer dielectric by a sputtering technique to forcibly form a void between wires, thereby improving permittivity of a semiconductor device. CONSTITUTION: A metal wire pattern(102) is formed on a semiconductor substrate(100). An interlayer dielectric(104) as an oxide film is formed on the substrate, on which the metal wire pattern is formed, by a sputtering technique. In the sputtering process, while sputtering a silicon target, an oxygen source is blown into a sputtering chamber to form the oxide film. A void(106) is formed in the interlayer dielectric. The void reduces a parasitic capacitance together with the interlayer dielectric to increase an operating speed of a semiconductor device. Since the interlayer dielectric has a hardness similar to a CVD(chemical vapor deposition) oxide film. An additional CVD oxide film is not needed. After completely depositing the interlayer dielectric, interlayer dielectric is planarized by a CMP(chemical mechanical polishing) process.
