Abstract: A semiconductor package including a substrate, a semiconductor device, a protection layer, a bonding wire, and a molding compound is provided. The substrate has a contact pad and a solder mask, and the contact pad is exposed from the solder mask. The semiconductor device is disposed on the substrate. The protection layer is disposed on the contact pad. The bonding wire connects the semiconductor device to the contact pad. An end of the bonding wire penetrates the protection layer and bonds with a portion of a surface of the contact pad to form a bonding region. The protection layer covers an entire surface of the contact pad except the bonding region. The molding compound covers the semiconductor device, the contact pad, and the bonding wire.

Abstract: A substrate having single patterned metal layer includes a patterned base having at least a plurality of apertures, the patterned metal layer disposed on the patterned base, and a first surface finish layer. Parts of the lower surface of the patterned metal layer are exposed by the apertures of the patterned base to form a plurality of first contact pads for downward electrical connection externally, and parts of the upper surface of the patterned metal layer function as a plurality of second contact pads for upward electrical connection externally. The first surface finish layer is disposed at least on one or more surfaces of the second contact pads, and the first surface finish layer is wider than the second contact pad beneath. A package applied with the substrate disclosed herein further comprises at least a die conductively connected to the second contact pads of the substrate.

Abstract: A chip package structure includes a substrate, a die, and a package body. The substrate includes a single patterned, electrically conductive layer, and a patterned dielectric layer adjacent to an upper surface of the electrically conductive layer. A part of a lower surface of the electrically conductive layer forms first contact pads for electrical connection externally. The patterned dielectric layer exposes a part of the upper surface of the electrically conductive layer to form second contact pads. The electrically conductive layer exposes the lower surface of the patterned dielectric layer on a lower periphery of the substrate. The die is electrically connected to the second contact pads, the patterned dielectric layer and the die being positioned on the same side of the electrically conductive layer. The package body is disposed adjacent to the upper surface of the electrically conductive layer and covers the patterned dielectric layer and the die.

Abstract: The present invention relates to a substrate of a window ball grid array package. The substrate includes at least one window, a first conductive layer, a second conductive layer, a dielectric layer, a plurality of first vias and a plurality of second vias. The window penetrates the substrate. The first conductive layer has a plurality of fingers and at least one first power/ground plane, and the fingers are disposed at the periphery of the window. The second conductive layer has at least one second power/ground plane. The dielectric layer is disposed between the first conductive layer and the second conductive layer. The first vias electrically connect the first power/ground plane to the second power/ground plane. The second vias are disposed between the fingers and the window, and electrically connect some of the fingers to the second power/ground plane. Thus, the substrate can control the characteristic impedance and increase the signal integrity.
