This is a Scanning Electron Microscope image of metal oxide film on silicon substrate. The sparkling objects are made by water vapor emitted from the oxide layer during deoxidation process. The sparkling ranges from 3 to a few ten microns. In the center of the broken layer by water vapor, we can see the silicon substrate intermittently.
