ABSTRACT:
A semiconductor device has passive components integrated with the circuit and encapsulated in a plastic package for solder ball or leaded attachment. A plastic chip-scale semiconductor device has a substrate made of a plurality of patterned insulating layers alternating with patterned electrically conductive layers, the layers mutually adhering to form the substrate. The layers include a plurality of passive electrical components, such as capacitors, inductors, and resistors, and routing lines. Most routing lines terminate in a first plurality of bondable contact pads and a second plurality of solderable contact pads. The components and lines form a web and are configured mostly in a narrow peripheral band at least partially around a central substrate area, and are operable with high performance in conjunction with an integrated circuit (IC) chip. The chip is attached to the central substrate area and electrically connected to the first plurality of contact pads, respectively, whereby the passive components are integrated with the IC. Plastic encapsulation material surrounds the chip, first plurality of contact pads, and passive components such that the outline of the material is approximately the same as the outline of the chip.
