| Abstract: | The double-exposure technique,which is used for optical lithography,has the advatages to enhance the contrast and the resolution,to improve the depth of focus and finally to improve the lithography quality. The principle and several double-exposure techniques are introduced,the double-exposure technique with the phase-shifting mask and the optical proximity correction are used for the enhancement of the lithography resolution.An example of double-exposure techniques and its computer simulat ed results are presented. |
