A semiconductor device of an embodiment includes: a first semiconductor element; a first insulating resin that seals the first semiconductor element; a wiring substrate having a pad; a first wiring that extends from the first semiconductor element toward the wiring substrate, and has a first head portion and a first column portion, the first column portion connected to the first semiconductor element and the first head portion exposed on a surface of the first insulating resin; and a first conductive bonding agent that electrically connects the first head portion of the first wiring and the pad. When a surface of the first head portion facing a side of the first insulating resin is defined as a first surface. A surface of the first insulating resin on a side of the wiring substrate is defined as a second surface. A distance from a surface of the wiring substrate on a side of the first insulating resin to the first surface is defined as a first distance, and a distance from a surface of the wiring substrate on the side of the first insulating resin to the second surface is defined as a second distance. The first distance is shorter than the second distance.

In an embodiment, a device includes: a substrate having a first side and a second side opposite the first side; an interconnect structure adjacent the first side of the substrate; and an integrated circuit device attached to the interconnect structure; a through via extending from the first side of the substrate to the second side of the substrate, the through via being electrically connected to the integrated circuit device; an under bump metallurgy (UBM) adjacent the second side of the substrate and contacting the through via; a conductive bump on the UBM, the conductive bump and the UBM being a continuous conductive material, the conductive bump laterally offset from the through via; and an underfill surrounding the UBM and the conductive bump.

A method of increasing a volume and a height of a solder bump present on a contact pad of a substrate is provided, including the steps: a) placing a solder ball having a predetermined volume in a capillary which is placed over the solder bump, b) liquefying the solder ball by applying laser energy from the laser source to the solder ball through the capillary, c) ejecting the liquefied solder ball from the capillary onto the solder bump by applying pressurized gas to the liquefied solder ball through the capillary, and d) melting the solder bump by transferring thermal and kinetic energy to the solder bump from the ejected liquefied solder ball and merging the liquefied solder ball with the melted solder bump.

A microelectronic device includes a die with input/output (I/O) terminals, and a dielectric layer on the die. The microelectronic device includes electrically conductive pillars which are electrically coupled to the I/O terminals, and extend through the dielectric layer to an exterior of the microelectronic device. Each pillar includes a column electrically coupled to one of the I/O terminals, and a head contacting the column at an opposite end of the column from the I/O terminal. The head extends laterally past the column in at least one lateral direction. Methods of forming the pillars and the dielectric layer are disclosed.

A semiconductor package and a manufacturing method thereof are described. The semiconductor package includes a package having dies encapsulated by an encapsulant, a redistribution circuit structure, first and second modules and affixing blocks. The redistribution circuit structure is disposed on the package. The first and second modules are disposed on and respectively electrically connected to the redistribution circuit structure by first and second connectors disposed there-between. The first and second modules are adjacent to each other and disposed side by side on the redistribution circuit structure. The affixing blocks are disposed on the redistribution circuit structure and between the first and second modules and the redistribution circuit structure. The affixing blocks include first footing portions located below the first module, second footing portions located below the second module, and exposed portions exposed from the first and second modules. The affixing blocks join the first and second modules to the redistribution circuit structure.
