Zusammenfassung:There is provided a semiconductor device having a device isolation region of STI structure formed on a silicon substrate so as to define a device region, wherein the device isolation region comprises a device isolation trench formed in the silicon substrate, and a device isolation insulation film filling the device isolation trench. At least a surface part of the device isolation insulation film is formed of an HF-resistant film.
