Design of automatic detection algorithm for dislocation contrasts in birefringence images of SiC wafers

– IOPscience

Abstract

Birefringence imaging
is one of the powerful methods for non-destructive characterization of defects in the semiconductor crystals.

However, due to the complicated and unclear contrasts of dislocations in the birefringence image,

it was considered to be difficult to automatically detect the position of the dislocation contrasts by the conventional image processing.

In the present study,
we designed the automatic detection algorithm for the dislocation contrasts taking into account the characteristic feature of the dislocation contrasts, which were always pair of black and white contrasts.

To detect the large change in the contrast level near the dislocation contrast,

the automatic detection algorithm
was constructed by using a variance filter.

Finally,
we succeeded in detecting the position of the dislocation contrasts with relatively high precision and sensitivity.
