Abstract:

The present invention may be a semiconductor device including of a fluorinated insulating film and a SiCN film deposited on the fluorinated insulating film directly, wherein a density of nitrogen in the SiCN film decreases from interface between the fluorinated insulating film and the SiCN film. In the present invention, the SiCN film that is highly fluorine-resistant near the interface with the CFx film and has a low dielectric constant as a whole can be formed as a hard mask.

Abstract(Chinese):

本发明可以是包括直接沉积在氟化绝缘膜上的氟化绝缘膜和SiCN膜的半导体器件，其中SiCN膜中的氮密度从氟化绝缘膜和SiCN膜之间的界面减小。在本发明中，作为硬掩模，可以形成与CFx膜的界面附近具有高介电常数的SiCN膜作为整体的低介电常数。
