Abstract:
1. A system for the manufacture of a semiconductor device, the system comprising: a first exposure unit with a first degree of freedom; wherein the first exposure unit exposes a first pattern on a semiconductor substrate in a shape adjusted with the first degree of freedom; a first pattern forming unit for developing a first pattern formed through a first exposure step performed by the first exposure unit; a second exposure unit, with a different exposure method than the first exposure unit and a second degree of freedom equal to or lower than the first degree of freedom; wherein the second exposure unit exposes a second pattern on the semiconductor substrate aligned with the first pattern in a shape adjusted with the second degree of freedom; a second pattern forming unit for developing a second pattern formed through a second exposure step performed by the second exposure unit; a pattern measuring unit for conducting a pattern measuring step, wherein the pattern measuring unit measures a difference in at least one of the shape and position between the first pattern and the second pattern; and a pattern adjustment unit for conducting a pattern adjustment step, wherein the the pattern adjustment unit relies on said difference to adjust the shape of a first pattern in a successive first patterning step performed after the first patterning step in which the difference is measured.
