Patent ID: 6977718

Claim:
A lithography method for selectively exposing parts of first and second targets, comprising: performing a first patterning of a first target, wherein the first patterning includes: directing light from a light source through a re-configurable reflective condenser in a first configuration to a first reflective reticle portion; and reflecting the light from the first reflective reticle portion to a first target portion to be selectively exposed; after performing the first patterning, re-configuring the reflective condenser to a second configuration, wherein the re-configuring results in altering of light characteristics of light exiting the reflective condenser; and after the re-configuring, performing a second patterning of a second target, wherein the second patterning includes: directing light from a light source through the re-configurable reflective condenser in the second configuration to a second reflective reticle portion; and reflecting the light from the second reflective reticle portion to a second target portion to be selectively exposed.
