    摘要: Disclosed herein are various methods of forming conductive contacts with reduced dimensions and various semiconductor devices incorporating such conductive contacts. In one example, one method disclosed herein includes forming a layer of insulating material above a semiconducting substrate, wherein the layer of material has a first thickness, forming a plurality of contact openings in the layer of material having the first thickness and forming an organic material in at least a portion of each of the contact openings. This illustrative method further includes the steps of, after forming the organic material, performing an etching process to reduce the first thickness of the layer of insulating material to a second thickness that is less than the first thickness, after performing the etching process, removing the organic material from the contact openings and forming a conductive contact in each of the contact openings.

    摘要: A contact element may be formed on the basis of a hard mask, which may be patterned on the basis of a first resist mask and on the basis of a second resist mask, to define an appropriate intersection area which may represent the final design dimensions of the contact element. Consequently, each of the resist masks may be formed on the basis of a photolithography process with less restrictive constraints, since at least one of the lateral dimensions may be selected as a non-critical dimension in each of the two resist masks.

    摘要: Methods are provided for fabricating integrated circuits that include forming first and second spaced apart gate structures overlying a semiconductor substrate, and forming first and second spaced apart source/drain regions in the semiconductor substrate between the gate structures. A first layer of insulating material is deposited overlying the gate structures and the source/drain regions by a process of atomic layer deposition, and a second layer of insulating material is deposited overlying the first layer by a process of chemical vapor deposition. First and second openings are etched through the second layer and the first layer to expose portions of the source/drain regions. The first and second openings are filled with conductive material to form first and second spaced apart contacts, electrically isolated from each other, in electrical contact with the first and second source/drain regions.
