Abstract
Devices and methods for reducing lead inductance in integrated circuit (IC) packages. More specifically to an integrated circuit package configuration for high speed applications where the inductance of the leads is reduced or minimized in high capacity semiconductor device packages. The integrated circuit package assembly comprises a substrate, semiconductor device, insulating covering or coating, if desire, a semiconductor device retainer, lead frame, and wire bond interconnections.
