Method of Double Patterning, Method of Processing a Plurality of Semiconductor Wafers and Semiconductor Device

摘要

A method of double patterning is disclosed. The method includes forming a first photosensitive layer; exposing the first photosensitive layer using a first reticle; developing the first photosensitive layer thereby forming a first image pattern including first elements; forming a second photosensitive layer; exposing the second photosensitive layer using the first reticle; and developing the second photosensitive layer thereby forming a second image pattern.
