The semiconductor device includes a substrate, a thin film transistor formed on the substrate and having a semiconductor layer, a gate insulating layer, a gate electrode, and an interlayer dielectric, and a contact hole penetrating the gate insulating layer and the interlayer dielectric and exposing a portion of the semiconductor layer. The contact hole has a multiple profile in which an upper portion of the contact hole has a wet etch profile and a lower portion of the contact hole has at least one of the wet etch profile and a dry etch profile. | 08-27-2009 |
