  • Patent number: 7319065
    Abstract: A semiconductor component having a composite via structure with an enhanced aspect ratio and a method for manufacturing the semiconductor component. Vias having a first aspect ratio are formed in a contact layer disposed on a semiconductor substrate and filled with a metal. The metal is planarized and a dielectric layer is formed over the contact layer. Via extension structures having the same aspect ratio as those in the contact layer are formed in the dielectric layer and aligned with the vias in the contact layer. The vias in the dielectric layer are filled with metal and the metal is planarized. The contact vias in the contact layer and the dielectric layer cooperate to form a composite via structure having the enhanced aspect ratio. Additional dielectric layers having via structures can be included in the composite contact structure to further enhance the aspect ratio of the via structure.

  • Patent number: 7314793
    Abstract: During the formation of a transistor element, sidewalls spacers are removed or at least partially etched back after ion implantation and silicidation, thereby rendering the mechanical coupling of a contact etch stop layer to the underlying drain and source regions more effective. Hence, the mechanical stress may be substantially induced by the contact etch step layer rather than by a combination of the spacer elements and the etch stop layer, thereby significantly facilitating the stress engineering in the channel region. By additionally performing a plasma treatment, different amounts of stress may be created in different transistor devices without unduly contributing to process complexity.

The electrically conductive material and the underlying dielectric layers are anisotropically etched to form a dielectric structure on which a gate electrode is disposed. A metal layer is formed on the dielectric structure and the gate electrode and treated so that portions of the metal layer diffuse into the porous dielectric layer. Then the metal layer is removed.

  • Patent number: 7310155
    Abstract: A system that facilitates extraction of line edge roughness measurements that are independent of proprietorship of a metrology device comprises a structure patterned onto silicon with known line edge roughness values associated therewith. A metrology device obtains line edge roughness measurements from the structure, and a correcting component generates an inverse function based upon a comparison between the known line edge roughness values and the measured line edge roughness values. The metrology device can thereafter measure line edge roughness upon a second structure patterned on the silicon, and the inverse function can be applied to such measured line edge roughness values to enable obtainment of line edge roughness measurements that are independent of proprietorship of the metrology device.
