Method of forming a metal interconnection in a semiconductor device |
| abstract |
A method includes at least one of: forming a metal interconnection in a semiconductor device; forming an inter-metal dielectric layer over a substrate and/or a lower metal layer; forming a photoresist pattern over an inter-metal dielectric layer; forming a via hole by selectively etching an inter-metal dielectric layer using a photoresist pattern as a mask; forming an ionization layer in a via plug by ion implantation on a sidewall of a via hole; forming a barrier metal layer and a via plug in the via hole; and/or forming a metal interconnection. In embodiments, a barrier metal layer may include titanium nitride and/or a via plug may include tungsten. |
