    摘要: A substrate is provided having semiconductor device structures formed in and on the substrate. The semiconductor device structures comprise conductor layers embedded in openings in dielectric layers having a dielectric constant of less than 4.5. The dielectric layer has a roughness between the dielectric and the conductor wherein the roughness of the dielectric layer divided by the thickness of a barrier layer underlying the conductor layer is 0 to 1. The integrated circuit structure is prepared for failure analysis by removing the low dielectric constant dielectric layers and exposing the conductor layers for further failure analysis by optical examination or scanning electron microscope (SEM).

    摘要: A method of forming a strained silicon layer on a relaxed, low defect density semiconductor alloy layer such as SiGe, has been developed. In a first embodiment of this invention the relaxed, low density SiGe layer is epitaxially grown on an silicon layer which in turn is located on an underlying SiGe layer. During the epitaxial growth of the overlying SiGe layer defects are formed in the underlying silicon layer resulting in the desired, relaxation, and decreased defect density for the SiGe layer. A second embodiment features an anneal procedure performed during growth of the relaxed SiGe layer, resulting in additional relaxation and decreased defect density, while a third embodiment features an anneal procedure performed to the underlying silicon layer prior to epitaxial growth of the relaxed SiGe layer, again allowing optimized relaxation and defect density to be realized for the SiGe layer. The ability to obtain a strained silicon layer on a relaxed, low defect density SiGe layer, allows devices with enhanced carrier mobility to be formed in the surface of the strained silicon layer, with decreased risk of leakage due the presence of the underlying, relaxed, low defect density SiGe layer.
