    Abstract: A method of manufacturing metallic interconnects for an integrated circuit includes forming an interconnect layout including at least one line including a non-diffusing material, forming a diffusing barrier layer on the line, forming an opening extending completely through the diffusing barrier layer and exposing a portion of the line, depositing a diffusing layer on the diffusing barrier layer such that a portion of the diffusing layer contacts the portion of the line, and thermally reacting the diffusing layer to form the metallic interconnects. Thermally reacting the diffusing layer chemically diffuses a material of the diffusing layer into the at least one line and causes at least one crystalline grain to grow along a length of the at least one line from at least one nucleation site defined at an interface between the portions of the diffusing layer and the line.

    Abstract: A method provides a source-drain stressor for a semiconductor device including source and drain regions. Recesses are formed in the source and drain regions. An insulating layer covers the source and drain regions. The recesses extend through the insulating layer above the source and drain regions. An intimate mixture layer of materials A and B is provided. Portions of the intimate mixture layer are in the recesses. The portions of the intimate mixture layer have a height and a width. The height divided by the width is greater than three. A top surface of the portions of the intimate mixture layer in the recesses is free. The intimate mixture layer is reacted to form a reacted intimate mixture layer including a compound AxBy. The compound AxBy occupies less volume than a corresponding portion of the intimate mixture layer.

    Abstract: Integrated circuit devices including contacts and methods of forming the same are provided. The devices may include a fin on a substrate, a gate structure on the fin and a source/drain region in the fin at a side of the gate structure. The devices may further include a contact plug covering an uppermost surface of the source/drain region and a sidewall of the gate structure. The contact plug may include an inner portion including a first material and an outer portion including a second material different from the first material. The outer portion may at least partially cover a sidewall of the inner portion, and a portion of the outer portion may be disposed between the sidewall of the gate structure and the sidewall of the inner portion.

    Abstract: Exemplary embodiments provide methods and systems for fabricating a metal source-drain stressor in a MOS device channel having improved tensile stress. Aspects of exemplary embodiment include forming a recess in source and drain areas; forming a metal contact layer on surfaces of the recess that achieves low contact resistivity; forming a metallic diffusion barrier over the metal contact layer; forming a layer M as an intimate mixture of materials A and B that substantially fills the recess; capping the layer M with a capping layer so that layer M is fully encapsulated and the capping layer prevents diffusion of A and B; and forming a compound AxBy within the layer M via a thermal reaction resulting in a reacted layer M comprising the metal source-drain stressor.
