FIG. 1 is a schematic sectional view of a conventional ultraviolet irradiation apparatus used for the above-mentioned purpose. Inside the processing chamber 1, a processing stage 1a is provided.
A work W to be processed, such as a substrate on which a circuit is formed, is placed on the upper surface of the substrate. A loading / unloading port 1c is provided on one side surface of the processing chamber 1, and the workpiece W is loaded and unloaded by the transport system 2 via the loading / unloading port 1c. On the other hand, a light irradiation box 3 is placed above the processing chamber 1 so as to surround the upper surface of the processing chamber, and is fixed to each other via, for example, a hinge R1. Inside the light irradiation box 3, two sets of lamps L that emit light including ultraviolet rays, for example, a bar-shaped high-pressure mercury lamp, and two mirrors M that reflect light including ultraviolet rays emitted from the lamps L are substantially parallel. The lamp L is fixed to the bottom 3a of the light irradiation box 3 via the lamp position adjusting mechanism A, and the mirror M is fixed to the mirror mounting portion 3d of the light irradiation box 3.

Further, a light transmitting window F made of a quartz glass plate or the like is provided at the bottom 3a of the light irradiation box 3 which is in contact with the processing chamber 1, and includes a direct light from the lamp L and a light from the mirror M, including ultraviolet rays. The reflected light is irradiated onto the work W through the light transmission window F. In addition, a duct 4 is provided above the light irradiation box 3, and the duct 4 is connected to an exhaust system (not shown). Then, when the lamp L is turned on, the exhaust damper 4a is opened to exhaust the air in the light irradiation box 3, and the air outside the light irradiation box 3 is taken in from the air inlet 3c provided on the side surface of the light irradiation box 3. That is, when the lamp L is turned on, the heat inside the light irradiation box 3 is exhausted through the duct 4 so that the heat generated by the lighting of the lamp L does not accumulate inside the light irradiation box 3. The lamp L is cooled by taking in air from outside.

By the way, as for the lamp L, as the lighting time elapses, the ultraviolet irradiance (hereinafter sometimes referred to as illuminance) and the illuminance distribution decrease, and the illuminance and the illuminance set by the user based on the processing process. It is necessary to replace when the illumination distribution becomes lower. When replacing the lamp L, as shown in FIG. 2, the light irradiation box 3 is lifted up in the direction of arrow Y and held around the hinge R1 as the center of rotation. Next, the light transmission window F is removed from the bottom 3a of the light irradiation box 3, and the used lamp L and the new lamp L are exchanged. Here, when installing a new lamp L, it is necessary to adjust the position of the lamp L with respect to the mirror M and the balance of the illuminance of the two lamps so that the set illuminance and the illuminance distribution are obtained.
The light irradiation box 3 of the conventional ultraviolet irradiation apparatus is provided with a lamp position adjusting mechanism A in advance, and the position of the lamp L can be adjusted using the lamp position adjusting mechanism A. However, after replacing the lamp L, in order to confirm whether the desired illuminance and illuminance distribution were obtained, the light transmission window F was attached to the light irradiation box 3, and the light irradiation box 3 was rotated in the direction opposite to the arrow Y. Then, it is necessary to confirm the position of the illuminance and the illuminance distribution measuring device on the processing stage 1a by turning on the lamp L. When the desired illuminance and illuminance distribution are not obtained, the lamp L is turned off, the light irradiation box 3 is again rotated and held in the direction of the arrow Y, the light transmission window F is removed, and the lamp L is turned off. It is necessary to adjust and replace the position of L again.

In this embodiment, the irradiation unit support 6 is provided with the concave portion 62a as a guide portion. However, the structure of the guide portion is not limited to this. For example, the structure of the guide portion may be a convex portion. The exhaust port 5 may be formed with a concave portion that engages with the convex portion. Further, it is also possible to adopt a structure in which a wheel is provided on one of the guide portion and the exhaust port of the irradiation unit support, and the irradiation unit support slides on the guide portion by rotation of the wheel. And, by adopting the above configuration, by increasing the size of the irradiation unit,
Even when the weight increases, the slide in the guide portion can be easily performed.

As described above, according to the light irradiation box of the ultraviolet irradiation apparatus and the irradiation unit of the ultraviolet irradiation apparatus of the present invention, the irradiation unit having the lamp and the mirror provided on the holding member when replacing the lamp. Is moved to the outside of the light irradiation box along the guide portion. Then, a new irradiation unit, which is provided on the holding member by adjusting the lamp and the mirror so that a desired illuminance and illuminance distribution is obtained, is inserted into the inside of the light irradiation box, and the inside of the light irradiation box is guided along the guide portion. And fix it. The exhaust duct provided in the light irradiation box and the exhaust port provided in the holding member are connected at the same time that the light irradiation unit is supported and fixed to the light irradiation box. Therefore, the lamp provided inside the light irradiation box of the ultraviolet irradiation device can be quickly replaced, and the desired illuminance and illuminance distribution can be easily obtained. Further, as described above, since the position of the lamp L with respect to the work W is determined,
At a desired illuminance and illuminance distribution. Further, it is possible to sufficiently cool the lamp provided in the irradiation unit of the ultraviolet irradiation device so that the lamp is stably turned on.
