    摘要: A CMP apparatus and process sequence. The CMP apparatus includes multiple polishing pads or belts and an in-line metrology tool which is interposed between adjacent polishing pads or belts in the apparatus. A material layer on each of multiple wafers is successively polished on the polishing pads or belts. The metrology tool is used to measure the thickness of a material layer being polished on each of successive wafers in a lot prior to the final polishing step, in order to precisely polish the layer to a desired target thickness at the final polishing step. This renders unnecessary an additional process cycle to polish the layer on each wafer to the desired target thickness. The metrology tool may be modularized as a unit with the polishing pads or belts.

    摘要: A thin wafer handling structure includes a semiconductor wafer, a release layer that can be released by applying energy, an adhesive layer that can be removed by a solvent, and a carrier, where the release layer is applied on the carrier by coating or laminating, the adhesive layer is applied on the semiconductor wafer by coating or laminating, and the semiconductor wafer and the carrier is bonded together with the release layer and the adhesive layer in between. The method includes applying a release layer on a carrier, applying an adhesive layer on a semiconductor wafer, bonding the carrier and the semiconductor wafer, releasing the carrier by applying energy on the release layer, e.g. UV or laser, and cleaning the semiconductor's surface by a solvent to remove any residue of the adhesive layer.
