摘要:
It is an object of the present invention to cure an insulating film of a semiconductor device in a short time while keeping a low dielectric constant. In the present invention, a coating film made of porous MSQ is formed on a substrate, the substrate on which the porous MSQ is formed is placed in a vacuum vessel, and high-density plasma processing at a low electron temperature based on microwave excitation is applied to the coating film by using a plasma substrate processing apparatus, thereby causing an intermolecular dehydration-condensation reaction of hydroxyls in a molecule and another molecule included in the porous MSQ to bond the molecules together, so that a cured insulating film is generated while a low dielectric constant is maintained.
