Abstract:

A structure and method for an insulator layer having carbon-graded layers above a substrate is disclosed, wherein the concentration of carbon increases in each successive carbon-graded layer above the substrate. The insulator comprises a low-k dielectric having a dielectric constant less than 3. 3. The carbon-graded layer increases adhesion between the substrate and the insulator and between the insulator and the conductor layer. The structure may also include stabilization interfaces between the carbon-graded layers. More specifically, the carbon-graded layers include a first layer adjacent the substrate having a carbon content between about 5% and 20%, a second layer above the first layer having a carbon content between about 10% and 30%, and a third layer above the second layer having a carbon content between about 20% and 40%.

International Classification:

H01L 29/06

US Classification:

257506

Abstract:

A substrate is provided. An STI trench is formed in the substrate. A fill material is formed in the STI trench and then planarized. The substrate is exposed to an oxidizing ambient, growing a liner at a bottom and sidewalls of the STI trench. The liner reduces the Vt-W effect in high-k metal gate devices.

US Classification:

427 8

Abstract:

An apparatus for processing a layer on a workpiece includes a source of reactant fluid, a reaction chamber having a support for the workpiece and a fluid delivery apparatus for feeding an input fluid into the reaction chamber with the input fluid being utilized to process the material. An infrared sensor is adapted to cooperate with the fluid delivery apparatus for sensing the concentration of a component of the input fluid. The infrared sensor includes an infrared light source positioned to direct a beam of infrared light at an infrared light detector through the input fluid. The infrared light detector produces an electrical output signal indicative of the amount of light received by the detector and therefore not absorbed by the input fluid.

Abstract:

A metal connection for an integrated circuit device is effectively "cast" in place at any level of an integrated circuit. The "mold" for the connection is formed by depositing and patterning a sacrificial material, such as aluminum oxide or other metal oxides, and covering the sacrificial material with a protective material such as silicon dioxide or other insulators. After forming bore holes to the deposit of sacrificial material through the protective layer, the sacrificial material is removed by isotropic etching to form a cavity beneath and at least partially overlaid by the protective layer. Alternatively, a defect may be produced below the protective layer and filled with metal either with or without enlargement by further removal of material. This cavity is then filled with metal by deposition of the metal by, for instance, evaporation, sputtering and chemical vapor deposition or combinations thereof. Connections formed by this technique can be produced at any level of the integrated circuit and do not interfere with surface wiring.
