Problems solved by technology

Due to the space occupied by the trigger electrodes and the spacing required to avoid inadvertent discharges between the inner electrodes and the trigger electrodes in adjacent slots, the size of the inner electrodes is limited and cannot be arranged along the entire volume of the discharge vessel, thus making it difficult to Ensuring a sufficiently large discharge area within the discharge vessel

[0052] figure 1 A sectional view showing an excimer lamp device according to a first embodiment of the present invention. figure 2 A longitudinal sectional view of the excimer lamp 1 used in this excimer lamp device is shown.

[0053] The excimer lamp 1 has a vessel 5 made of quartz glass and having a length of 850 nm. Inside the container 5 are provided an inner tube 2 whose outer diameter is 23 mm and whose thickness is 1.2 mm, an outer tube 3 whose outer diameter is 35 mm and whose thickness is 1.2 mm, and an inner tube 2 and an outer tube 3 formed by a concentric arrangement. Airtight double cylindrical discharge space 4 in the space.

[0072] Figure 4 A sectional view showing an excimer lamp in an excimer lamp device according to a second embodiment of the present invention.

[0073] Compared with the first embodiment, the significant difference in the excimer lamp device according to the second embodiment lies in the following two points: First, the stable starting voltage of the excimer lamp is changed so as to have a frequency of 2 MHz and 8.1 kVp- p; and secondly, using a halogen lamp and a power circuit for starting the halogen lamp as an ultraviolet emitter. Other configurations are substantially the same as those of the first embodiment, so the same reference numerals used in the first embodiment are used to describe these elements.

[0074] The halogen lamp 23 (power consumption 100W, rated voltage 12V) used as an ultraviolet emitter mainly reflects light whose wavelength region is in the visible and infrared range, but a small part of the light falls within the wavelength range of 250nm to 380nm i...

[0086] Compared with the second embodiment, the excimer lamp device according to the third embodiment is mainly different in the following: an infrared transmission filter 30 for transmitting infrared rays in the light emitted from the excimer lamp 1 is provided; An infrared detector is a silicon photodiode 40 for detecting infrared rays, and a lighting controller 50 for controlling the excimer lamp 1 and the halogen lamp 23 to be switched on. The other configurations are substantially the same as those of the first and second embodiments, so the same reference numerals in the first and second embodiments are used to describe these elements.

Abstract

By arranging a pair of electrodes along the entire length of the discharge vessel, the present invention provides an excimer lamp device with advanced start-up performance for start-up application and start-up stability under voltage variations without any Trigger electrodes. The ultraviolet emitter is arranged to irradiate the discharge gas within the discharge vessel with ultraviolet light, and the excimer lamp is activated by exposure to ultraviolet light from the ultraviolet emitter.

Description

technical field [0001] The present invention relates to an excimer lamp device that radiates ultraviolet rays for, for example, curing resin or semiconductor wafers, surface treatment and / or surface cleaning of glass substrate lamps. Background technique [0002] An excimer lamp included in an excimer lamp device is disclosed in Japanese Unexamined Patent Application Publication No. 2000-311658. [0003] The excimer lamp is an electrodeless field discharge excimer lamp comprising a discharge vessel containing a discharge gas therein and having an external electrode wound around its outside. A highly electrically insulating tube with an inner electrode wound around its outside is inserted approximately in its center into the discharge vessel. Excimer lamp illumination is realized by applying high frequency from 1 MHZ to 100 MHZ to the internal electrodes via electric field discharge. The highly insulating tube has a trigger electrode and an inner electrode with two branch s...
