Abstract
An integrated circuit power supply interconnection technique is disclosed having a highly doped, low resistivity substrate for distribution of the integrated circuit's most positive supply voltage. The substrate functions as the most positive voltage point and accomodates devices that are normally connected directly to this most positive supply voltage. A dielectric buried layer overlies a portion of the substrate and isolates the substrate supply voltage from devices that are not connected directly to the most positive supply voltage.
