Abstract:
A contact structure and a method for forming the contact structure are provided. The contact structure includes an insulating layer formed on a substrate. The contact structure includes a conductive element formed on the substrate and in the insulating layer. The contact structure includes a first liner formed in the insulating layer and on sidewalls of an upper portion of the conductive element. The contact structure includes a second liner formed on the sidewalls of the conductive element. A conductive contact plug is formed by the second liner and the conductive element. At the upper portion of the conductive element, the second liner is interposed between the conductive element and the first liner. At the lower portion of the conductive element, the second liner is interposed between the conductive element and the insulating layer.

Claim (Index 9):
A method for forming a contact structure, comprising:\n forming an insulating layer on a substrate; performing a first etching process to form a contact hole in the insulating layer; forming a first liner material on sidewalls and a bottom of the contact hole; performing a second etching process to remove the first liner material on the bottom of the contact hole and to increase a depth of the contact hole, wherein the first liner material remaining on the sidewalls of the contact hole forms a first liner; forming a second liner on the sidewalls and the bottom of the contact hole; and filling a conductive material into the contact hole to form a conductive element on the substrate and in the insulating layer, wherein the second liner and the conductive element form a conductive contact plug, wherein the second liner is interposed between the conductive element and the first liner at an upper portion of the conductive element, and wherein the second liner is interposed between the conductive element and the insulating layer at a lower portion of the conductive element, and wherein a horizontal bottom portion of the second liner is interposed between the conductive element and the substrate.
