SEMICONDUCTOR STRUCTURE, AND METHODS FOR FABRICATING SAME

摘要

The invention relates to a method of producing a semiconductor structure, the method comprising: - forming in a first semiconductor material substrate (30) a first dielectric area (32a-c) of a first dielectric material having a first thickness and a second dielectric area (34a-b) having a second thickness, - assembling said first substrate with a second semiconductor material substrate (40), - fracturing the portion of the substrate in which the weakened layer is produced, and- thinning one or both substrates.
