    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: A method of forming an improved seal ring structure is described. A continuous metal seal ring is formed along a perimeter of a die wherein the metal seal ring is parallel to the edges of the die and sloped at the corner of the die so as not to have a sharp corner and wherein the metal seal ring has a first width at the corners and a second width along the edges wherein the first width is wider than the second width.
