Package Level Tuning Techniques for Propagation Channels of High-Speed Signals

摘要

Various semiconductor chip carrier substrate circuit tuning apparatus and methods are disclosed. In one aspect, a method of manufacturing is provided that includes assembling a semiconductor chip carrier substrate with a first input/output site adapted to electrically connect to an external component and a second input/output site adapted to electrically connect to an input/output site of a semiconductor chip. An inductor is placed in the semiconductor chip carrier substrate. The inductor is electrically connected between the first and second input/output sites. The inductor has a preselected inductance to reduce an impedance discontinuity between the first input/output site or the second input/output site due to coupling to a second conductor in the semiconductor chip carrier substrate.
