Abstract

A method of fabricating a semiconductor device is provided. The method includes preparing a semiconductor substrate having first and second regions, forming a mask layer pattern on the second region, growing an oxidation retarding layer on the first region and removing the mask layer pattern. The method further includes growing a silicon oxide layer on the semiconductor substrate to form gate insulating layers having different thicknesses from one another on the first and second regions.
