摘要:
A structure comprises a plurality of connectors formed on a top surface of a first semiconductor die, a second semiconductor die formed on the first semiconductor die and coupled to the first semiconductor die through the plurality of connectors and a first dummy conductive plane formed between an edge of the first semiconductor die and the plurality of connectors, wherein an edge of the first dummy conductive plane and a first distance to neutral point (DNP) direction form a first angle, and wherein the first angle is less than or equal to 45 degrees.

A die includes a substrate, a metal pad over the substrate, and a passivation layer that has a portion over the metal pad. A dummy pattern is disposed adjacent to the metal pad. The dummy pattern is level with, and is formed of a same material as, the metal pad. The dummy pattern forms at least a partial ring surrounding at least a third of the metal pad.

A structure comprises a top metal connector formed underneath a bond pad. The bond pad is enclosed by a first passivation layer and a second passivation layer. A polymer layer is further formed on the second passivation layer. The dimension of an opening in the first passivation layer is less than the dimension of the top metal connector. The dimension of the top metal connector is less than the dimensions of an opening in the second passivation layer and an opening in the polymer layer.

A die includes a substrate, a metal pad over the substrate, and a passivation layer covering edge portions of the metal pad. A metal pillar is formed over the metal pad. A portion of the metal pillar overlaps a portion of the metal pad. A center of the metal pillar is misaligned with a center of the metal pad.

Substrate stand-offs for use with semiconductor devices are provided. Active pillars and dummy pillars are formed on a first substrate such that the dummy pillars may have a height greater than a height of the active pillars. The dummy pillars act as stand-offs when joining the first substrate to a second substrate, thereby creating greater uniformity. In an embodiment, the dummy pillars may be formed simultaneously as the active pillars by forming a patterned mask having openings with a smaller width for the dummy pillars than for the active pillars. When an electro-plating process of the like is used to form the dummy and active pillars, the smaller width of the dummy pillar openings in the patterned mask causes the dummy pillars to have a greater height than the active pillars.

A device includes a first work piece bonded to a second work piece. The first work piece includes a solder resist at a surface of the first work piece, wherein the solder resist includes a solder resist opening, and a bond pad in the solder resist opening. The second work piece includes a non-reflowable metal bump at a surface of the second work piece. A solder bump bonds the non-reflowable metal bump to the bond pad, with at least a portion of the solder bump located in the solder resist opening and adjoining the non-reflowable metal bump and the bond pad. A thickness of the solder resist is greater than about 50 percent a height of the solder bump, wherein the height equals a distance between the non-reflowable metal bump and the bond pad.

A pillar structure for a substrate is provided. The pillar structure may have one or more tiers, where each tier may have a conical shape or a spherical shape. In an embodiment, the pillar structure is used in a bump-on-trace (BOT) configuration. The pillar structures may have circular shape or an elongated shape in a plan view. The substrate may be coupled to another substrate. In an embodiment, the another substrate may have raised conductive traces onto which the pillar structure may be coupled.
