Abstract: <P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a semiconductor device for forming a plurality of gate oxide films with different film thickness with each other in a way of not causing a damage to the gate oxide films.  <P>SOLUTION: The manufacturing method adopts the two-layer resist method to first form a thick film lower layer resist film on the gate oxide films 12 on the entire area of a substrate, then uses a Si containing resist material to form an upper layer resist film on the lower layer resist film, and forms an upper layer resist mask 24 covering a second substrate region by the lithography processing. The method uses a mask 24 to apply patterning to the lower layer resist film for forming a thick film resist mask 22 and then removes the gate oxide film 12 of a first substrate region 14, and forms another gate oxide film on the entire substrate after removing the resist mask. Thus, this method can form the thin gate oxide film on the first substrate region and the thick gate oxide film formed by a stacked film comprising the gate oxide film 12 left on the second substrate region 16 and the newly formed gate oxide film on the gate oxide film 12. Since this method uses the thick film resist mask 22 for the etching mask, it is prevented that an etchant transmits through the resist mask to reach the gate oxide film resulting in causing erosion or the like.  <P>COPYRIGHT: (C)2004,JPO
