Method and system for measuring polycrystalline chunk size and distribution in the charge of a Czochralski process
A method and system for determining polycrystalline silicon chunk size for use with a Czochralski silicon growing process. Polycrystalline silicon chunks are arranged on a measuring background. A camera captures an image of the chunks. An image processor processes the image and determines the dimens...

| description | A method and system for determining polycrystalline silicon chunk size for use with a Czochralski silicon growing process. Polycrystalline silicon chunks are arranged on a measuring background. A camera captures an image of the chunks. An image processor processes the image and determines the dimensions of the chunks based on the captured image. A size parameter associated with the chunks is determined. |
