Abstract:

An integrated circuit (IC) device includes a substrate having a top surface including active circuitry including a plurality of I/O nodes, and a plurality of die pads coupled to the plurality of I/O nodes. A first dielectric layer including first dielectric vias is over the plurality of die pads. A redirect layer (RDL) including a plurality of RDL capture pads is coupled to the plurality of die pads over the first dielectric vias. A second dielectric layer including second dielectric vias is over the plurality of RDL capture pads. At least one of the second dielectric vias is a crack arrest via that has a via shape that includes an apex that faces away from a neutral stress point of the IC die and is oriented along a line from the neutral stress point to the crack arrest via to face in a range of 30 degrees from the line. Under bump metallization (UBM) pads are coupled to the plurality of RDL capture pads over the second dielectric vias, and metal bonding connectors are on the UBM pads.

International Classification:

H01L 23/495
H01L 21/58

US Classification:

257666, 438123, 257E21499, 257E23039

Abstract:

An integrated circuit package includes a die, a bump, an underbump metallization layer formed between the bump and the die, a portion of the underbump metallization layer under the bump having a first radius, and a redistribution layer formed between the underbump metallization layer and the die. The redistribution layer has a pad positioned under the underbump metallization layer. The pad has a second radius, and makes contact with the underbump metallization layer. The second radius is less than or equal to the first radius. The integrated circuit package also includes a first dielectric layer disposed between the die and the redistributing layer.

International Classification:

H01L 23/52
G06F 9/455

US Classification:

257778, 716 11, 257E23141

Abstract:

An integrated circuit device includes a functional circuit die with a patterned rewiring layer defining a first rewiring pad and one or more second rewiring pads on opposite sides of a neutral point of the die. The device also includes at least one dielectric layer having bump opening features over the rewiring pads. The device further includes electrically conductive bump pad features formed on the dielectric layer over the bump opening features. The bump pad features make contact with the rewiring pads via the bump opening features. In the device, a center of the bump opening features are laterally offset from a center of the bump pad feature towards a neutral point of the die.
