Method and apparatus for reducing noise in electrical power supplied to a semiconductor

摘要

A method and apparatus for decoupling a voltage supply from a semiconductor device is provided. A substrate has a plurality of spaced apart electrical connections positioned on thereon, wherein at least first and second ones of the connections are coupled to first and second terminals of a voltage supply respectively. A capacitor is coupled to the substrate and interstitially positioned within the spaced apart connections. The capacitor has first and second leads coupled with the first and second terminals of the voltage supply. A semiconductor device is coupled to the substrate in mating relationship with the pattern of spaced apart electrical connections, wherein the capacitor is positioned below the semiconductor device and immediately adjacent the voltage supply terminals of the semiconductor device.
