Method for producing a substrate including a step of thinning with stop when a porous zone is detected |
摘要 |
A method for producing a substrate, the method including: forming a porous zone in an inner layer of the substrate; progressively thinning a thickness of the substrate towards the inner layer including the porous zone; completing the progressively thinning by polishing; and controlled stopping of the polishing by detecting the porous zone during the polishing, the detecting including measuring at least one measurable physical parameter admitting a significant variation during a transition between two layers. |
