- the weight of the substrate is mainly supported by the holder main body, and the holder main body is manufactured to be thick and strong because it is pivoted and rocked at a predetermined angle. Needs to be increased, and the substrate holder is becoming very heavy with the increase in size of the substrate. In recent years, glass substrates larger than 2000 mm have appeared, and thus glass substrates When the size of the substrate holder increases, the size of the substrate holder supporting the peripheral portion has to be increased. In order to rotate such a large and heavy substrate holder to a predetermined angle for macro inspection, a large driving force is required, and there is a problem that the entire inspection apparatus becomes large.
- the length of the substrate support becomes longer in proportion to the size of the substrate, and the support itself is easily vibrated in the vertical direction by the rotation or swinging operation of the substrate holder.
- Another problem is that stagnation easily occurs due to the weight of the member itself. If the rigidity of the substrate support portion is increased to prevent this, the weight of the substrate holder is further increased, which is not preferable.
