A semiconductor device and a process for producing the same. The device has two conducting layers that are spaced from each other and an organic insulating film for electrically insulating these two conducting layers from each other. The organic insulating film contains contact holes with plugs being embedded therein so as to electrically connect these two conducting layers by the plugs. The process contains a step of forming the organic insulating film on the lower conducting layer. An impurity having a kinetic energy is introduced into the organic insulating film. Next, contact holes are formed in the organic insulating film, and then plugs are formed in the contact holes. An upper conducting layer is formed on the organic insulating film so as to be electrically connected to the plugs.

Semiconductor devices and an insulating layer with an impurity

A semiconductor producing method includes the steps of: forming an SOG pre-film on a semimanufactured semiconductor device by means of spin-on-glass (SOG) process; and forming a modified SOG film by doping the SOG pre-film with at least one impurity ion selected from: inert gas ions; simple ions of Groups IIIb, IVb, Vb, VIb, VIIb, IVa and Va elements; and ions of compounds containing any one of Groups IIIb, IVb, Vb, VIb, VIIb, IVa and Va elements.

Process for producing semiconductor devices

A pair of source/drain regions are formed on a semiconductor substrate at a predetermined interval. A gate insulator film is formed on the semiconductor substrate between the source/drain regions of the pair. A gate electrode is formed on the gate insulator film. A film for covering the gate electrode and the source/drain regions has a low permeability against water and a hydroxide group, and has a thickness greater than 3 nm and less than 5 nm.
