Abstract
An ultra lightweight semiconductor device comprises a substrate electrode, a body of semiconductor material, and a top electrode, and is manufactured by a process wherein the thickness dimension of a portion of the substrate electrode is decreased so as to reduce the weight of the device. The portions of the device having a thick substrate serve to support and reinforce the device during processing and handling. These portions may subsequently be severed away to further reduce the weight of the device. Also disclosed are configurations of ultra lightweight semiconductor devices.
