    摘要: A semiconductor device is prepared by an annealing process to interconnect at least two components of the device by a conductor line surrounded by an insulator material. The annealing process results in formation of residual stresses within the conductor line and the insulator material. A notch is designed in the layout on a selective portion of the mask for patterning conductor line. The existence of a shape of notch on the selective portion generates extra stress components within the conductor line than if without the existence of the notch. The position of the notch is selected so that the extra stress components substantially counteract the residual stresses, thereby causing a net reduction in the residual stresses. The reduction in the residual stresses results in a corresponding mechanical stress migration and therefore improvement in the reliability of the device.

    摘要: The present invention provides two or more test structures/substructures (100) that are used in a test pattern (500, 600, 700, 800) to determine a cracking threshold for a dielectric material (104) on a substrate. Each test structure/substructure (100) includes two metal structures (102) separated by the dielectric material (104) having a width (G) which is different for each test structure/substructure (100). The cracking threshold will be approximately equal to the largest width (G) of dielectric material (104) that is cracked after processing. The present invention also provides a method for determining the cracking threshold for the dielectric material (104). Two or more test structures (100) are formed on the substrate (402) followed by a determination of whether the dielectric material (104) between the two metal structures (102) for each test structure (100) has cracked during processing (404).

    摘要: A structure for a multi-level interconnect inter-level dielectric layer (ILD), a method of manufacturing thereof, and a semiconductor device including the ILD layer. The ILD layer includes a first low-dielectric constant material sub-layer, and a second low-dielectric constant material sub-layer disposed over the first low-dielectric constant material sub-layer. The second low-dielectric constant material sub-layer has at least one different material property than the first low-dielectric constant material sub-layer. A third low-dielectric constant material sub-layer is disposed over the second low-dielectric constant material sub-layer, the third low-dielectric constant material sub-layer having at least one different material property than the second low-dielectric constant material sub-layer. The first, second and third low-dielectric constant materials sub-layers are preferably comprised of the same material, deposited continuously in one or more deposition chambers while the deposition conditions such as the gas flow rate, power, or gas species are adjusted or changed.
