An integrated circuit structure includes a first chip including a first edge; and a second chip having a second edge facing the first edge. A scribe line is between and adjoining the first edge and the second edge. A heat spreader includes a portion in the scribe line, wherein the heat spreader includes a plurality of vias and a plurality of metal lines. The portion of the heat spreader in the scribe line has a second length at least close to, or greater than, a first length of the first edge.

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.

A system and method for forming an underbump metallization (UBM) is presented. A preferred embodiment includes a raised UBM which extends through a passivation layer so as to make contact with a contact pad while retaining enough of the passivation layer between the contact pad and the UBM to adequately handle the peeling and shear stress that results from CTE mismatch and subsequent thermal processing. The UBM contact is preferably formed in either an octagonal ring shape or an array of contacts.

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.

An integrated circuit structure comprising a fuse and a method for forming the same are provided. The integrated circuit structure includes a substrate, an interconnection structure over the substrate, a fuse connected to the interconnection structure, and an anti-reflective coating (ARC) on the fuse. The ARC has an increased thickness and acts as a remaining oxide, and no further remaining passivation layer exists on the ARC.

A system and method for conductive pillars is provided. An embodiment comprises a conductive pillar having trenches located around its outer edge. The trenches are used to channel conductive material such as solder when a conductive bump is formed onto the conductive pillar. The conductive pillar may then be electrically connected to another contact through the conductive material.

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.

A 3D semiconductor package using an interposer is provided. In an embodiment, an interposer is provided having a first die electrically coupled to a first side of the interposer and a second die electrically coupled to a second side of the interposer. The interposer is electrically coupled to an underlying substrate, such as a packaging substrate, a high-density interconnect, a printed circuit board, or the like. The substrate has a cavity such that the second die is positioned within the cavity. The use of a cavity may allow smaller conductive bumps to be used, thereby allowing a higher number of conductive bumps to be used. A heat sink may be placed within the cavity to aid in the dissipation of the heat from the second die.
