摘要:
An ashing apparatus includes a treatment chamber having an object to be processed therein, and a lamp chamber having an ultraviolet lamp that radiates the object with an ultraviolet beam. The ashing apparatus is configured to accurately maintain an irradiation distance between a light source and the object. Thus, it is possible to efficiently remove a smear from a wiring board. The treatment chamber and the lamp chamber are moved relative to each other and in parallel to a surface of the object to be processed. The treatment chamber has a stage that supports the object, a gas inlet opening for supplying a treatment gas into the treatment chamber, and a gas outlet opening for discharging the treatment gas. An ultraviolet transmitting window member that partitions the treatment chamber and the lamp chamber from each other is fixed to the treatment chamber.

Provided are a desmearing method and a desmearing device which are able to reliably remove a smear derived from any of an inorganic substance and an organic substance, and eliminate the need to use a chemical that requires a waste liquid treatment. The desmearing method of the present invention is directed to a desmearing method for a wiring substrate material that is a laminated body of insulating layers made from resin containing a filler and a conductive layer, and includes an ultraviolet irradiation treatment step for irradiating the wiring substrate material with ultraviolet beams with a wavelength of 220 nm or less, and a physical vibration treatment step for applying physical vibrations to the wiring substrate material which has undergone the ultraviolet irradiation treatment step.

A light irradiation apparatus that can uniformly treat the entire to-be-treated surface of a to-be-treated subject having a light irradiation apparatus including: a treatment chamber in which a to-be-treated subject is disposed; an ultraviolet emitting lamp for emitting vacuum ultraviolet rays to the to-be-treated subject; and gas supply means for supplying a treatment gas containing a source of active species to the treatment chamber. A gas supply port for supplying the treatment gas to the treatment chamber and a gas discharge port for discharging the gas in the treatment chamber are provided on respective sides of a to-be-treated subject placement area in the treatment chamber so as to form a gas flow channel through which the treatment gas flows from the gas supply port toward the gas discharge port in the treatment chamber. How much of a gas amount at the gas supply port reaches the gas discharge port is controlled to be 60 to 95%.
