System, apparatus and method of selective laser repair for metal bumps of semiconductor device stack
Abstract:
Exemplary embodiments of the selective laser repair apparatus and method may allow the repair of metal bumps in a semiconductor device stack by applying a laser beam to a damaged and/or defective bump. Metal bumps may be repaired and individual chips and/or packages forming a device stack need not be separated. The operation of a control unit and a driving unit may position a laser unit such that a laser beam may be irradiated at the damaged and/or defective metal bump. An X-ray inspection unit may obtain information about the damaged and/or defective metal bump.
