Presented herein are an interconnect structure and method for forming the same. The interconnect structure includes a contact pad disposed over a substrate and a connector disposed over the substrate and spaced apart from the contact pad. A passivation layer is disposed over the contact pad and over connector, the passivation layer having a contact pad opening, a connector opening, and a mounting pad opening. A post passivation layer including a trace and a mounting pad is disposed over the passivation layer. The trace may be disposed in the contact pad opening and contacting the mounting pad, and further disposed in the connector opening and contacting the connector. The mounting pad may be disposed in the mounting pad opening and contacting the opening. The mounting pad may be separated from the trace by a trace gap, which may optionally be at least 10 μm.

A method of forming a package on package (PoP) structure includes forming a first die package, and bonding an external connector of a second die package to a solder paste layer of the first die package. The forming the first die package includes forming a contact pad over a substrate, attaching a metal ball with a convex surface to the contact pad, and applying a solder paste layer over a distal end of the metal ball and leaving at least a portion of the metal ball without solder paste. The forming the first die package also includes attaching a semiconductor die to the substrate, and forming a molding compound between the semiconductor die and the metal ball, where the solder paste layer has a first portion extending above an upper surface of the molding compound and a second portion extending below the upper surface of the molding compound.

3D joining of microelectronic components and a conductively self-adjusting anisotropic matrix are provided. In an implementation, an adhesive matrix automatically makes electrical connections between two surfaces that have electrical contacts, and bonds the two surfaces together. Conductive members in the adhesive matrix are aligned to automatically establish electrical connections between at least partially aligned contacts on each of the two surfaces while providing nonconductive adhesion between parts of the two surfaces lacking aligned contacts. An example method includes forming an adhesive matrix between two surfaces to be joined, including conductive members anisotropically aligned in an adhesive medium, then pressing the two surfaces together to automatically connect corresponding electrical contacts that are at least partially aligned on the two surfaces. The adhesive medium in the matrix secures the two surfaces together.

An apparatus relating generally to a substrate is disclosed. In such an apparatus, a first bond via array has first wires extending from a surface of the substrate. A second bond via array has second wires extending from the surface of the substrate. The first bond via array is disposed at least partially within the second bond via array. The first wires of the first bond via array are of a first height. The second wires of the second bond via array are of a second height greater than the first height for coupling of at least one die to the first bond via array at least partially disposed within the second bond via array.

A semiconductor structure includes an oval-shaped pad and a dielectric layer. The oval-shaped pad is on a substrate and includes a major axis corresponding to the largest distance of the oval-shaped pad. The major axis is toward a geometric center of the substrate. The dielectric layer covers the substrate and surrounds the oval-shaped pad.

Stack packages are provided. The stack package includes a first chip and a second chip. The first chip includes a first chip body, first through electrodes penetrating the first chip body, and an insulation layer disposed on a bottom surface of the first chip body. The second chip includes a second chip body and bumps disposed on a top surface of the second chip body. The first and second chips are vertically stacked such that the bumps penetrate the insulation layer to pierce the first through electrodes and the top surface of the second chip body directly contacts the insulation layer. Related fabrication methods, electronic systems and memory cards are also provided.
