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.
