Wafer die separation |
摘要 |
A method of singulating a wafer starts with fracturing the wafer. The method may also include attaching the dicing tape sheet to a ring frame; relatively raising a portion of the dicing tape sheet supporting the wafer with respect to the ring frame; and attaching support tape to the ring frame and the dicing tape sheet. |

1. A method of singulating a wafer and separating die that are supported on a dicing tape sheet comprising:
fracturing wafer to form a plurality of singulation lines dividing the wafer into a plurality of dies; attaching the dicing tape sheet to a ring frame; relatively raising a portion of the sheet supporting the wafer with respect to the ring frame; and attaching a plurality of radially extending strips of support tape to the ring frame and the dicing tape sheet. |
