Abstract

The present invention is to lessen work burden on a user, to eliminate determination error, to prevent a substrate from being damaged, and to prevent prolonged working time by automatically determining whether or not a particle to be removed is present. A particle inspection and removal apparatus of the present invention includes a particle information acquisition section acquiring particle information on a particle adhering onto a substrate surface, a particle removal section removing the particle adhering onto the substrate surface, a comparison section comparing a threshold set for each of regions of the substrate surface with the particle information on each of the region obtained by the particle information acquisition section, and a particle removal control section controlling the particle removal section to remove the particle on the substrate surface based on a comparison result of the comparison section.

Claims (10)

1. A particle inspection and removal apparatus comprising:

a particle information acquisition section acquiring particle information on a particle adhering onto a substrate surface;

a particle removal section removing the particle adhering onto the substrate surface;

a comparison section comparing a condition for particle removal set for each of a plurality of regions on the substrate surface with the particle information on each of the regions obtained by the particle information acquisition section; and

a particle removal control section controlling the particle removal section to remove the particle on the substrate surface if a comparison result of the comparison section indicates that the particle information satisfies the condition,

wherein the substrate is a reticle for transferring a circuit pattern onto a semiconductor wafer or a reticle with a pellicle, and the regions are set for different circuit patterns formed on the reticle.

2. A particle inspection and removal program for inspecting and removing a particle adhering onto a substrate surface using a particle information acquisition section acquiring particle information on a particle adhering onto a substrate surface and a particle removal section removing the particle adhering onto the substrate surface, the particle inspection and removal program causing a computer to function as:

a comparison section comparing a condition for particle removal set for each of a plurality of regions on the substrate surface with the particle information on each of the regions obtained by the particle information acquisition section; and

a particle removal control section controlling the particle removal section to remove the particle on the substrate surface if a comparison result of the comparison section indicates that the particle information satisfies the condition,

wherein the substrate is a reticle for transferring a circuit pattern onto a semiconductor wafer or a reticle with a pellicle, and the regions are set for different circuit patterns formed on the reticle.
