Abstract
A method and structure for fabricating an electronic device using an SOI technique that results in formation of a buried oxide layer. The method includes fabricating at least one first component of the electronic device and fabricating at least one second component of the electronic device, wherein the first component and the second component are on opposite sides of the buried oxide layer, thereby causing the buried oxide layer to perform a function within the electronic device.
Entire circuits can be designed around this technique.
