Patent ID: 7557011

Claim:
A method for fabricating a semiconductor device, comprising the steps of: (a) forming a first hydrogen barrier film; (b) forming a capacitor device on the first hydrogen barrier film; (c) the step of etching an exposed portion of the surface of the first hydrogen barrier film, after the step (b) has been performed; (d) forming a second hydrogen barrier film so that the second hydrogen barrier film covers the capacitor device and comes into contact with the first hydrogen barrier film around the perimeter of the capacitor device, after the step (c) has been performed, and wherein the first and second hydrogen barrier films each contain at least one common type of atoms for allowing the first and second hydrogen barrier films to adhere to each other, the step (c) dissociates bonds of combining atoms of the type commonly contained in the first and second hydrogen barrier films to produce dangling bonds, and the first and second hydrogen barrier films adhere to each other by chemical bonding of the atoms of the common type.
