Abstract:
In a process for producing a semiconductor device having an upper conducting layer and a lower conducting layer that are spaced from each other and an organic insulating film for electrically insulating said upper conducting layer and said lower conducting layer from each other, said organic insulating film containing a contact hole having a plug embedded therein that connects said upper conducting layer and said lower conducting layer, said process comprising the steps of:forming the organic insulating film on said lower conducting layer;introducing one of a nitrogen ion and a boron ion, which serves as an impurity into said organic insulating film to decompose organic compounds contained in the organic insulating film and thus form a modified insulating film;forming said contact hole in said modified insulating film;forming said plug in said contact hole; andforming an upper conducting layer on said modified insulating film so as to be electrically connected to said plug.
