Patent ID: 8153495

Claim:
A method of manufacturing a semiconductor device, comprising: forming a polycrystalline film on a substrate; forming a gate insulator on the polycrystalline film; implanting ions into the polycrystalline film; forming a source and a drain in both sides of the polycrystalline film and a channel therebetween; forming a hydrogen-supplying film on the gate insulator; forming a gate electrode on the hydrogen-supplying film; forming an inner dielectric layer to cover the gate electrode and the hydrogen-supplying film; performing an annealing process to diffuse hydrogen atoms from the hydrogen-supplying film to the channel so as to transform unsaturated bonds into hydrogen bonds in the polycrystalline film; forming a hydrogen film on the inner dielectric layer; applying another annealing process to the hydrogen film; forming two wires to extend through the inner dielectric layer and the hydrogen film so as to contact with the source and the drain, respectively; and forming a passivation layer to cover the inner dielectric layer, wherein the passivation layer includes a silicon nitride with a plurality of hydrogen atoms.
