    摘要: A method for forming an integrated circuit structure includes forming a test wafer. The step of forming the test wafer includes providing a first semiconductor substrate; and forming a first plurality of unit blocks over the first semiconductor substrate. Each of the first plurality of unit blocks includes a plurality of connection block cells arranged as an array. Each of the connection block cells includes two connection blocks, and a metal line connecting the two connection blocks. The method further includes forming a plurality of unit block boundary lines separating the first plurality of unit blocks from each other; and forming a first plurality of metal lines connecting a portion of the first plurality of unit blocks.

    摘要: A scribe line layout design to reduce the damage caused by sawing the wafer is presented. An embodiment comprises metal plates located within the scribe lines and at least partially within the junctions of the scribe lines. Each of these metal plates has one or more slots to help relieve the pressure. Alternatively, instead of metal plates, grooves that may be filled with metal could be placed into the scribe lines. These metal plates could also be used concurrently with a seal ring for better protection during sawing.

    摘要: Keep out zones (KOZ) are formed for a through silicon via (TSV). A device can be placed outside a first KOZ of a TSV determined by a first performance threshold so that a stress impact caused by the TSV to the device is less than a first performance threshold while the first KOZ contains only those points at which a stress impact caused by the TSV is larger than or equal to the first performance threshold. A second KOZ for the TSV can be similarly formed by a second performance threshold. A plurality of TSVs can be placed in a direction that the KOZ of the TSV has smallest radius to a center of the TSV, which may be in a crystal orientation [010] or [100]. A plurality of TSV stress plug can be formed at the boundary of the overall KOZ of the plurality of TSVs.
