摘要： The present invention relates to a method of manufacturing a flash memory device. The method includes the steps of forming cell gate patterns and select transistor gate patterns on a semiconductor substrate; forming a low dielectric layer on the resultant structure; etching the low dielectric layer, leavinin gaps adjacent the cell gate patterns; and, forming a nitride layer spacer on one side wall of each of the select transistor gate patterns. The resulting flash memory device has an improved rate of change in the threshold voltage and reduces the contact resistance when a self-aligned contact method is subsequently performed.
