Abstract:
In a dual substrate stage, double exposure lithography system, a method comprising:loading a first reticle onto a reticle stage in an exposure system; loading, processing, and exposing a first pair of substrates, which are transported into and out of the exposure system via the dual substrate stage; exchanging the first reticle for a second reticle; processing and exposing the first pair of substrates, which are transported into and out of the exposure system via the dual substrate stage; exchanging a second pair of substrates for the first pair of substrates; processing and exposing the second pair of substrates, which are transported into and out of the exposure system via the dual substrate stage; exchanging the second reticle for the first reticle; processing and exposing the second pair of substrates, which are transported into and out of the exposure system via the dual substrate stage; exchanging a third pair of substrates for the second pair of substrates; processing and exposing the third pair of substrates, which are transported into and out of the exposure system via the dual substrate stage; exchanging the first reticle for the second reticle; and processing and exposing the third pair of substrates, which are transported into and out of the exposure system via the dual substrate stage.
