    摘要: Silicon oxide (210) is grown on a silicon region (130). At least a portion (210N) of the silicon oxide (210) adjacent to the silicon region (130) is nitrided. Then some of the silicon oxide (210) is removed, leaving the nitrided portion (210N). Additional silicon oxide is thermally grown on the silicon region (130) under the nitrided silicon oxide portion (210N). This additional silicon oxide and the nitrided portion (210N) form a silicon oxide layer (140) having a high nitrogen concentration adjacent to a surface opposite from the silicon region (130) and a low nitrogen concentration elsewhere. Another nitridation step increases the nitrogen concentration in the silicon oxide layer (140) adjacent to the silicon region, providing a double peak nitrogen profile.

    摘要: Thin oxide films are grown on silicon which has been previously treated with a gaseous or liquid source of chloride ions. The resulting oxide is of more uniform thickness than obtained on untreated silicon, thereby allowing a given charge to be stored on a floating gate formed over said oxide for a longer time than previously required for a structure not so treated.
