摘要
A maskless photolithoghrapic system includes a laser point-by-point scanning exposure unit, a plane-projection exposure unit, a mobile station and a calculation control unit that decomposes a pattern to be exposed, so that a pattern portion with a precision requirement below a pre-determined threshold is exposed by the laser point-by-point scanning exposure unit, and a pattern portion with a precision requirement greater than the pre-determined threshold is exposed by the plane-projection exposure unit; when conducting laser point-by-point scanning exposure on a sample on the mobile station, the light emitted by the laser point-by-point scanning exposure unit moves relative to the sample according to the pattern portion with a precision requirement below the pre-determined threshold; and when conducting plane-projection exposure on the sample, the plane-projection exposure unit emits light with a corresponding pattern shape onto the sample according to the graph with a precision requirement greater than the pre-determined threshold.
