Method for fabricating semiconductor device

A method for fabricating a semiconductor device includes forming a first wiring layer, the first wiring layer including a first metal wiring and a first interlayer insulating film wrapping the first metal wiring on a substrate, forming a first via layer, the first via layer including a first via that is in electrical connection with the first metal wiring, and a second interlayer insulating film wrapping the first via on the first wiring layer, and forming a second wiring layer, the second wiring layer including a second metal wiring that is in electrical connection with the first via, and a third interlayer insulating film wrapping the second metal wiring on the first via layer, wherein the third interlayer insulating film contains deuterium and is formed through chemical vapor depositionusing a first gas containing deuterium and a second gas containing hydrogen. 一种制造半导体器件的方法，包括：在衬底上形成第一布线层，所述第一布线层包括第一金属布线和包围所述第一金属布线的第一层间绝缘膜，在所述第一布线层上形成第一通孔层，所述第一通孔层包括与所述第一金属布线电连接的第一通孔和包围所述第一通孔的第二层间绝缘膜；并且在所述第一通孔层上形成第二布线层，所述第二
