Abstract:
1. An integrated circuit system comprising: providing a first aperture plate including a first dipole opening and a second dipole opening oriented in a first direction; providing a first mask including a first feature oriented in a second direction; exposing the first mask to a radiation source to form an image of the first feature on a photoresist material that possesses a geometry that is different from a structure to be formed on a substrate that includes the integrated circuit system; providing a second aperture plate including the first dipole opening and the second dipole opening oriented in a second direction; providing a second mask including a second feature oriented in a first direction, the first direction being substantially perpendicular to the second direction; aligning the second mask over the image of the first mask; and exposing the second mask to the radiation source to form an overlap region in the photoresist material and to define the structure on the substrate.
