Abstract
A method is used to form an intermetal dielectric layer. According to the invention, an unbiased-unclamped fluorinated silicate glass layer used as a protection layer is formed by high density plasma chemical vapor deposition on a biased-clamped fluorinated silicate glass layer formed by high density plasma chemical vapor deposition to prevent the biased-clamped fluorinated silicate glass layer from being exposed in a planarization process.
