Abstract:
1. A microlithography projection exposure installation, comprising: a first microlithography projection system, comprising: a second microlithography projection system, spatially separated from the first projection system, the second microlithography system comprising: a single light source assigned to both the first and second microlithography projection systems; and an adjustable optical deflector in a light path downstream of the single light source, wherein: the adjustable optical deflector is capable of deflecting light from the single light source along a first partial path to the first projection system or along a second partial path to the second projection system, and the first and second microlithography projection systems each comprise a positioning device configured to position the substrate with the aid of measurement such that the position of the second substrate relative to a position of the first substrate is configured to be set with a positional error that is not greater than a smallest structural size to be projected onto the substrate.
