A stack package may include a substrate having first and second faces opposite each other and an opening formed therein. The first semiconductor chip may be mounted on the first face of the substrate and include a through electrode in the middle region of the first semiconductor chip that is exposed through the opening. The second semiconductor chip may be stacked on the first semiconductor chip and electrically connected to the first semiconductor chip by the through electrode of the first semiconductor chip. The circuit pattern may be formed on the second face of the substrate and include a bonding pad arranged adjacent to the opening and electrically connected to the through electrode of the first semiconductor chip through the opening, an outer connection pad spaced apart from the bonding pad and a connection wiring extending from the opening to the outer connection pad via the bonding pad.

A decoupling capacitor, a wafer stack package including the decoupling capacitor, and a method of fabricating the wafer stack package are provided. The decoupling capacitor may include a first electrode formed on an upper surface of a first wafer, a second electrode formed on a lower surface of a second wafer, and an adhesive material having a high dielectric constant and combining the first wafer with the second wafer. In the decoupling capacitor the first and second electrodes operate as two electrodes of the decoupling capacitor, and the adhesive material operates as a dielectric of the decoupling capacitor.

An embodiment may comprise a test probe to measure electrical properties of a semiconductor package having ball-shaped terminals. The probe may include a signal tip and a ground tip. The signal tip may have a spherical lower surface allowing good contact with a ball-shaped signal terminal. The ground tip may be extended from a lower end of a ground barrel that encloses the signal tip. The ground tip may move independent of the signal tip by means of a barrel stopper and a spring. Thus, the probe can be used regardless of the size of and the distance between the package terminals.

A semiconductor chip package has a substrate that includes circuit lines provided on first and/or second surfaces, a power plane provided on the second surface, bump lands provided on the second surface and coupled to the circuit lines, and ball lands provided on the first surface. The package further has a semiconductor chip attached to the second surface of the substrate and electrically coupled to the circuit lines, and a dielectric layer provided on the second surface of the substrate. The dielectric layer surrounds laterally the chip, covers the power plane, and exposes the bump lands. The package further has a ground plane provided on both the chip and the dielectric layer, vertical connection bumps provided within the dielectric layer and on the bump lands and electrically coupled to the ground plane, and solder balls provided on the ball lands.

A vehicular power window safety device by which the state of a foreign object being stuck is recognized only when the foreign object makes contact with a weather strip mounted on the upper portion of a door frame, deforming the weather strip, and preventing an excessive contact between the window glass and run channel from being misjudged as an object being jammed therebetween and thereby enabling to obtain an operational trustworthiness on the power window safety device. The device comprises a motor for generating the driving power for lifting and lowering a window glass; a weather strip mounted on an upper area of a door frame and inherently provided with a sensor of which electric resistance is changed by pressure provided by a foreign object stuck in between the weather strip and the window glass due to the lifting of the window glass; and a controller for controlling the motor in response to signals supplied from the sensor.

In an integrated circuit (IC) chip and a flip chip package having the same, no wiring line is provided and the first electrode pad does not make contact with the wiring line in a pad area of the IC chip. Thus, the first bump structure makes contact with the first electrode regardless of the wiring line in the pad area. The second electrode pad makes contact with the wiring line in a pseudo pad area of the IC chip. Thus, the second bump structure in the pseudo pad area makes contact with an upper surface of the second electrode at a contact point(s) spaced apart from the wiring line under the second electrode.

A mounting substrate includes a substrate, a bonding pad and an induction heating pad. The bonding pad is formed on the substrate, and adhered to a solder ball to mount a semiconductor chip on the substrate. The induction heating pad is disposed adjacent to the bonding pad, the induction heating pad being induction heated by an applied alternating magnetic field to reflow the solder ball. The induction heating pad having a diameter greater than a skin depth in response to the frequency of the applied alternating magnetic field is selectively induction heated in response to a low frequency band of the alternating magnetic field. Accordingly, during a reflow process for a solder ball, the semiconductor chip may be mounted on the mounting substrate to complete a semiconductor package without damaging the mounting substrate, to thereby improve the reliability of the completed semiconductor package.
