ABSTRACT:
The invention concerns a method for minimizing “corner” effects in shallow silicon oxide trenches, by densifying the silicon oxide layer after it has been deposited in the trenches. Said densification is preferably carried out by irradiating the layer under luminous radiation with weak wavelength.
