| 摘要 |
A semiconductor device having a conductor line free of cracks is produced by forming an insulating layer on a semiconductor substrate, opening a contact hole in the insulating layer, forming a contact electrode comprising a high-melting point metal or a silicide of a high-melting point in the contact hole, filling a gap between the contact electrode and the side of the contact hole with polycrystalline silicon to form a substantially level surface, forming a conductor line on the level surface, and alloying the polycrystalline silicon with the conductor line and/or the contact electrode by heating.
