  • Patent number: 9026240
    Abstract: A coating and developing treatment apparatus includes a substrate transfer mechanism; and a defect inspection section. A transfer control part controls transfer of a substrate. A defect classification part classifies a defect based on the state of the defect. A storage part stores a transfer route of the substrate by the substrate transfer mechanism when the substrate has been treated by treatment sections. A defective treatment specification part specifies, based on a kind of the defect classified by the defect classification part and the transfer route of the substrate stored in the storage part, a treatment section which is a cause of occurrence of the classified defect, and judges presence or absence of an abnormality of the specified treatment section. The transfer control part controls the substrate transfer mechanism to transfer a substrate bypassing the treatment section which has been judged to be abnormal by the defective treatment specification part.

  • Publication number: 20140174482
    Abstract: In one embodiment, after rinsing a semiconductor substrate having a fine pattern formed thereon with pure water, the pure water staying on the semiconductor substrate is substituted with a water soluble organic solvent, and then, the semiconductor substrate is introduced into a chamber in a state wet with the water soluble organic solvent. Then, the water soluble organic solvent is turned into a supercritical state by increasing a temperature inside of the chamber. Thereafter, the inside of the chamber is reduced in pressure while keeping the inside of the chamber at a temperature enough not to liquefy the pure water (i.e., rinsing pure water mixed into the water soluble organic solvent), and further, the water soluble organic solvent in the supercritical state is changed into a gaseous state, to be discharged from the chamber, so that the semiconductor substrate is dried.
