Claim 17:
18. A method of forming a contact, comprising:
forming an interlayer insulating layer on a semiconductor substrate, the semiconductor substrate comprising a transistor;
forming a contact hole by etching the interlayer insulating layer;
forming a TiO2 layer on the interlayer insulating layer by supplying a source gas including TiCl4 and H2 onto the interlayer insulating layer;
forming a barrier layer by igniting a plasma using the source gas; and
forming a metal layer on the barrier layer,
wherein the forming the TiO2 layer includes adjusting a thickness of the TiO2 by adjusting a partial pressure of the TiCl4 to a level and maintaining the level.
