    • PURPOSE: A method for forming a low dielectric layer is provided to form a silicon carbide layer including a low dielectric constant, a low leakage current and an excellent mechanical property by introducing source gas of silicon, carbon and oxygen and inactive gas and by generating an electric field while using low frequency RF power and high frequency RF power, thereby making plasma discharge occurs in a reaction region. CONSTITUTION: Silicon source, carbon source, oxygen source and inactive gas are supplied to the inside of a reaction region in which a substrate is located. An electric filed is formed in the reaction region by using low frequency RF energy and high frequency RF energy generated from an RF power supply part. The silicon source is reacted with the carbon source to deposit a silicon carbide layer on the substrate. The RF power supply part generates and supplies average power to the surface of an electrode used in plasma discharge in the reaction region and generates high frequency RF power and low frequency RF power during a process.
