Inventor: CHOI JAE SIK
IPC: H01L21/56
Filed: 2019-03-28
Abstract: The present invention relates to a method for forming and packaging a semiconductor die to reduce the height of silicon debris (grooving burr or Si debris) by changing the structure of a passivation insulating film formed on a scribe line of the semiconductor die. The present invention provides a structure in which a passivation insulating film is removed in a scribe line region positioned between die regions, which is an IC chip region. With this structure, when a laser beam is emitted to the scribe line region according to a laser grooving process, the silicon debris is formed at a predetermined height from an upper surface of an interlayer insulating layer, not the passivation insulating layer. Therefore, the present invention can solve the problem of blocking the movement of an ACF conductive ball by the silicon debris formed from the conventional passivation insulating layer.
