A method for fabricating semiconductor components is performed using a laser
scanner
and a laser imaging process. A substrate, such as a semiconductor wafer, containing
multiple semiconductor components, such as dice or packages, is provided. The components
include integrated circuits, and component contacts in electrical communication
with the integrated circuits. Initially, the components are tested to identify
and locate good components and defective components on the substrate. Using data
from the testing step and the laser scanner, patterns of conductors are then formed
to either repair the defective components, to electrically isolate the defective
components for burn-in, or to form component clusters containing only the good
components. Alternately, using data from the testing step and the laser scanner,
a matching test board can be fabricated, and used to electrically engage the good
components, while the defective components remain isolated.
