This is a real
crystal lattice defect. It is remarkable because: |
| |
|
 |
It contains all 5 kinds of one-dimensional defects called dislocations that occur in fcc crystals.
|
|
It contains a two-dimensional defect - astacking fault. Two more stacking faults are seen in
the background. |
|
It is partially decorated with three-dimensional defects (small precipitates). |
|
It came into being by the agglomeration of zero-dimensional defects: Si interstitials. |
|
It was formed during the processing of Si integrated circuits |
|
It is a killer defect,
short-circuiting a transistor. |
|
It can only be identified by
transmission electron microscopy, one of the most important methods for the investigation of defects. |
