Abstract
There is provided a semiconductor device manufacturing apparatus and a semiconductor device manufacturing method capable of recovering a damage of a low dielectric insulating film exposed to COplasma to obtain the low dielectric insulating film in a good state, thus improving performance and reliability of a semiconductor device. The semiconductor device manufacturing method includes: an etching process for etching a low dielectric insulating film formed on a substrate; a COplasma process for exposing the substrate to COplasma after the etching process; and a UV process for irradiating UV to the low dielectric insulating film after the COplasma process.
