摘要:
An embodiment of the invention provides a chip package including a semiconductor substrate (100) having a first surface (100a) and a second surface (100b) opposite thereto. A dielectric layer (130) is overlying the first surface of the semiconductor substrate and comprises an opening exposing a conducting pad (150). A side recess (200) is on at least a first side of the semiconductor substrate, wherein the side recess extends from the first surface (100a) towards the second surface (100b). An upper recess is on at least a first side of the dielectric layer outside the conducting pad. A conducting layer is electrically connected to the conducting pad (150) and extends to the upper recess and the side recess.

There is a need to improve reliability of the semiconductor device. A semiconductor device includes a printed circuit board and a semiconductor chip mounted over the printed circuit board. The semiconductor chip includes a pad, an insulation film including an opening to expose part of the pad, and a pillar electrode formed over the pad exposed from the opening. The printed circuit board includes a terminal and a resist layer including an opening to expose part of the terminal. The pillar electrode of the semiconductor chip and the terminal of the printed circuit board are coupled via a solder layer. Thickness h 1 of the pillar electrode is measured from the upper surface of the insulation film. Thickness h 2 of the solder layer is measured from the upper surface of the resist layer. Thickness h 1 is greater than or equal to a half of thickness h 2 and is smaller than or equal to thickness h 2 .

A flip-chip electrical coupling between first and second electrical components (250, 260). The coupling includes a bump (210) and a pad (220). The bump (210) is electrically coupled to the first electrical component (250). The pad (220) is electrically coupled to the second electrical component (260). The pad (220) is electrically coupled to and dimensioned smaller than a corresponding coupling surface (214) of the bump (210). The pad (220) and bump (210) may be electrically coupled together using an ultrasonic stub bump bonding process, conductive epoxy, etc.
