  • Patent number: 8748289
    Abstract: A method for manufacturing a semiconductor device makes it possible to efficiently polish with a polishing tape a peripheral portion of a silicon substrate under polishing conditions particularly suited for a deposited film and for silicon underlying the deposited film. The method includes pressing a first polishing tape against a peripheral portion of a device substrate having a deposited film on a silicon surface while rotating the device substrate at a first rotational speed, thereby removing the deposited film lying in the peripheral portion of the device substrate and exposing the underlying silicon. A second polishing tape is pressed against the exposed silicon lying in the peripheral portion of the device substrate while rotating the device substrate at a second rotational speed, thereby polishing the silicon to a predetermined depth.
