Claim Text:
1. A method comprising: dividing a pattern into a first component pattern and a second component pattern; shaping radiation from a light source via a three-pore illumination shaper, wherein a first pore from the three pores of the three-pore illumination shaper is defined by a first edge of the shaper extending along a first axis and an opposing second edge of the shaper extending along a second axis, the first edge being connected to the second edge by a first plurality of edges of the shaper extending along the first axis and a second plurality of edges of the shaper extending along the second axis, the first axis being substantially perpendicular to the second axis, wherein a second pore from the three pores of the three-pore illumination shaper is defined by a third edge of the shaper extending along the first axis and an opposing fourth edge of the shaper extending along the second axis, the third edge being connected to the fourth edge by a third plurality of edges of the shaper extending along the first axis and a fourth plurality of edges of the shaper extending along the second axis; and projecting the first component pattern onto the substrate using the shaped radiation.
