The excimer lamp includes: a discharge container having a substantially quadrangular shape with a cross section, the discharge container having a pair of flat walls extending in a longitudinal direction and a pair of side walls connecting the flat walls; a pair of external electrodes facing each other disposed on outer surfaces of the pair of flat walls, respectively; a first internal electrode disposed inside the discharge container so as to extend toward inner surfaces of the pair of flat walls; and a second internal electrode disposed inside the discharge container at a position spaced apart from the first internal electrode in the longitudinal direction so as to extend toward the inner surfaces of the pair of flat walls. The first internal electrode and the second internal electrode are respectively disposed at positions between end parts and central parts of the external electrodes in the longitudinal direction.

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.

Desmearing method and desmearing device

The present invention has as its object the provision of a desmear treatment device and a desmear treatment method capable of reliably performing a desmear treatment with high treatment efficiency. In the desmear treatment method of the present invention, when irradiating a to-be-treated object disposed in a treatment space with vacuum ultraviolet rays via an ultraviolet transmitting window member to remove smear in the to-be-treated object, a treatment gas containing active species to be activated by the irradiation of the vacuum ultraviolet rays and having contained moisture is supplied into the treatment space. The desmear treatment device includes treatment gas supply means having a humidifying mechanism for causing a treatment gas containing active species to be activated by vacuum ultraviolet rays from an ultraviolet light source to contain moisture.

A template washing method and a photowashing apparatus which ensure removal of resist residual remaining on a pattern surface of a template, a pattern forming method and a nanoimprint apparatus which ensure formation of patterns with fewer defects are provided. The template washing method of the invention for photowashing the pattern surface of the template used in nanoimprint includes a vacuum-ultraviolet light irradiation process for irradiating the pattern surface of the template with vacuum ultraviolet light under an atmosphere of dry air.
