Description of the invention () (Technical field to which the invention belongs) < Please read the notes on the back before filling out this page) This invention relates to the surface of substrates used for semiconductors, glass, metals or polymer compounds Ultraviolet irradiation devices such as dielectric excitation lamps that perform cleaning and modification, especially for use with liquid crystal displays, PDP (Plasma Display Panel: Plasma Display Panel), or FED (Field Emission Display). The rectangular substrate surface is cleaned or modified by an ultraviolet irradiation device. (Conventional technology) Recently, attention has been paid to cleaning or modification of a substrate for a display and a silicon surface using an ultraviolet irradiation device such as a dielectric excitation lamp. The dielectric excitation lamp is filled with a discharge gas such as xenon and krypton bromide that form excited molecules in the discharge vessel, and is excited to form excited molecules by being silently charged, and then the light emitted by the excited molecules is taken out. The dielectric system uses synthetic quartz glass and the like. The dielectric excitation lamp emits short-wavelength ultraviolet rays below 175 nm and selectively and efficiently generates light of a single wavelength close to the spectrum. Therefore, it has various characteristics not available in conventional low-pressure mercury lamps and high-pressure arc discharge lamps. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. For example, when a dielectric excitation lamp uses a gas containing xenon, xenon atoms are excited to generate an excited state. When the excited state is reduced to xenon atoms, light with a wavelength of about 172 nm is generated. After the 172 nm wavelength light is irradiated to the atmosphere, the oxygen in the atmosphere is absorbed by the light, and ozone is generated from the oxygen. The generated ozone decomposes to produce active oxygen species and oxidizes organic matter. In addition, the energy of photons at 1 72 nm is as high as 7.2 e, which is greater than the binding energy of most organic compounds, so they can cut off their binding.

Dielectric excitation lamps are disclosed in, for example, Japanese Patent Laid-Open No. 2-73 53, U.S. Patent Publication No. 4,8 3, 7,484 and the like. Fig. 9 shows a schematic configuration of a dielectric excitation lamp. The dielectric excitation lamp 90 is composed of a double tube 91 and an excitation gas 92 such as xenon or the like, which is made of quartz glass, and sealed therein. An external electrode 93 and an internal electrode 94 are provided on the outer periphery and the inner periphery of the double tube 91, respectively. The external electrode 93 uses a mesh electrode in order to pass the light emitted from the dielectric excitation lamp. An inert gas 95 such as nitrogen and argon flows into the inner electrode 94 of the double tube 91, thereby suppressing the heat generation of the dielectric excitation lamp. Fig. 10 (A) is a schematic structural diagram of a lamp device including the dielectric excitation lamp 90 described above. The frame system of the lamp device 100 is a closed container, and the interior is filled with an inert gas such as nitrogen and argon, which do not easily absorb light. This suppresses the extent to which the ultraviolet rays radiated from the dielectric excitation lamp 90 are attenuated in the lamp device 100. A light-transmitting member 101 made of synthetic quartz glass or the like is provided below the lamp device 100 as a light extraction window. Ultraviolet rays emitted from the dielectric excitation lamp 90 pass through the light-transmitting member 101 and irradiate to the force port. Works. The lamp device 100 is further provided with a reflector 102 inside the reflector device. The reflector covers the upper part and the side part of the dielectric excitation lamp 90, and the light irradiated to the upper and the side faces downward, that is, the workpiece W, Light collection. Fig. 10 (B) shows the light amount distribution of the lamp device 100 over the width of its emission. From this curve, it can be understood that the amount of light is greatest under the dielectric excitation lamp, and it decays toward the periphery. -4- This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) ---! --------- f Packing -------- Order ---- -^ --- _ # (Please read the note on the back?

Description of Invention (3) In the past, the aforementioned dielectrics were used In the case of cleaning or modifying large glass substrates such as liquid crystals, PDPs, etc., the excitation lamp is a so-called multi-lamp integrated surface irradiation method in which a plurality of dielectric excitation lamps arranged in a line are used to irradiate the processed surface W collectively. FIG. 11 is a schematic configuration diagram showing a multi-lamp integrated surface irradiation method. The internal enqueuing device of the lamp device 1 1 0 has a plurality of dielectric excitation lamps 1 1 1. The pitch moment between the dielectric excitation lamps 11 1 is approximately 2 to 3 of the diameter of the dielectric excitation lamp η 1. Brilliance makes the amount of luminous light emitted by the dielectric excitation lamp reflected by each of the reflectors 1 12 as uniform as possible. In order to pass the light emitted from the dielectric excitation lamp π1 and irradiate the workpiece, a light transmitting member 13 made of synthetic quartz or the like is provided on the entire lower surface of the lamp device 110. However, in the case of performing cleaning or upgrading by the conventional multi-lamp integrated surface irradiation method, there are some problems described below. (1) As shown in Figure 10 (B), the amount of light emitted by each dielectric excitation lamp in its width direction is not uniform. Even if the arrangement of adjacent dielectric excitation lamps is optimized, each dielectric excitation lamp The amount of light emitted from time to time is still smaller than the amount of light directly below the dielectric excitation lamp. As a result, when the object to be processed is irradiated with ultraviolet rays for a certain period of time, the cumulative light amount of the object varies greatly, and the effect of cleaning or modifying the object is uneven. (2) It is necessary to irradiate large-scale glass substrates and other devices with ultraviolet rays. Because of the above-mentioned integrated surface irradiation, a considerable number of dielectric excitation lamps (and drive circuits for each lamp) must be provided. For example, when the size of the glass substrate is 680 legs X 880 legs, the multi-lamp integrated surface irradiation method usually requires 13 dielectric excitation lamps. In addition, it is necessary to make a large-scale paper size that applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) --- mt ------ --- installed --------- order- --- 丨 — _ # · (Please read the notes on the back before filling out this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 500630 A7 B7 V.

However, the water-cooled dielectric excitation lamp shown in FIG. 2 has the aforementioned cooling water 25 flowing inside the double tube, and even if a large driving power is input, it can prevent exceeding a predetermined amount of heat generation, thereby increasing the amount of luminous light. In one embodiment, the electric power per unit length of the dielectric excitation lamp is 15 W / Cm, and the amount of emitted light that is 5 times stronger than the aforementioned air-cooled type is obtained. -14- This paper size is in accordance with China National Standard (CNS) A4 (210 X 297 mm) ϋ nnnn ϋ ~ «ϋ ί ml I ί ϋ ϋ ϋ n a-0, · I nn IIII _ (Please read first Note on the back?

In addition, the initial position of the workpiece W considers the acceleration distance at which the moving speed of the workpiece w accelerates to a predetermined speed. In fact, its leading position (A in the figure) is located in front of the lamp device 40A. Fig. 5 shows an embodiment in which the workpiece w is moved back and forth in the ultraviolet irradiation range. In this embodiment, the workpiece W is moved back and forth across the ultraviolet irradiation range for cleaning or modification. That is, the processed object W provided in front of the lamp device 11 (on the left in the figure) is transferred to the ultraviolet irradiation range emitted by the lamp device 11 and temporarily when the processed surface completely passes the irradiation range. stop. Secondly, it is transferred in the reverse direction, and stops again after returning to the initial position through the ultraviolet irradiation range. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs In this embodiment, the processed object W passes twice under the lamp device 11. Therefore, in order to supply the processed object with the same cumulative light amount as in the case shown in Fig. 4, it is sufficient to move the processed object at a speed twice the speed described above. That is, in the case of this embodiment, the moving speed of the workpiece W in the ultraviolet irradiation range can be set to V = 2aPN / J or less.

The irradiation method of this embodiment is effective for reducing the environment where the floor area occupied by the device is more important than the processing speed. When the irradiation method according to this embodiment is implemented, the three lamp devices 40 A to 40 C in the foregoing embodiment are arranged at equal intervals. When the length in the moving direction of the processed object W is L, the pitch between the lamp devices 40 A to 40 C is determined based on (L + a) / N. Here, a is the width of each lamp device, and N is the number of lamp devices. In this embodiment, a three-lamp device is used, so its pitch moment is (L + a) / 3. In relation to the arrangement of the lamp device, the workpiece W is placed in front of the innermost lamp device (the lamp device 40C in the figure) located at the front end A in the moving direction. The three lamp devices 40A to 40C are turned on in accordance with the start of the movement of the forced work W. As the workpiece W moves, each of the lamp devices 40 A to 4 0C irradiates and processes the processed area before, middle, and rear areas. When the rear end B of the workpiece W exceeds the irradiation range of the foremost lamp device (the lamp device 40A in the figure), the entire irradiation of the processed surface by ultraviolet rays is completed. The moving distance of the workpiece W is the same as the pitch of the lamp described above (L + a) / N. As in the previous embodiment, the accumulated light amount required for sufficient processing of each area of the processed surface determines the moving speed of the processed object W. The irradiation of ultraviolet rays in various fields is performed by a dielectric excitation lamp, so according to the above formula (1), the moving speed V is below V = aP / 3. For example, an ultraviolet irradiation device using a lamp device with a width a = 75 mm and an average unit area of irradiated light amount P = 20mW / cm 2 is set to be required for processing -18- This paper size applies to China National Standard (CNS) A4 specifications ( 210 X 297 mm) (Please read Note 3 on the back before filling out this page) Install Γ--mmat I ϋ J ^ I mmmmmm 1 · __ ·· 1 n 1- I 500 500630 A7 ____B7___ 5. Description of the invention (17) (Please read the precautions on the back before filling in this page) The cumulative light amount per unit area J is 100mJ / cm 2, and the processing speed v is v == 75 when processing the workpiece with L = 88〇mm · 20/100 = 15 wakes / S, in addition, the pitch moment between the aforementioned lamp devices and the moving distance of the workpiece W, from (L + a) / N = (880 + 75) / 3, the output is about 318.3 mm. From the above data, the processing time of the processed object W (the time from the start to the end of the movement) is calculated, t = 3 1 8 · 3/15, which is about 21.2 seconds. Fig. 7 is a graph showing the change of the distribution of the cumulative light amount of the workpiece W with respect to time in the aforementioned embodiment. Here, for the sake of simplicity, the illuminance distribution generated by a lamp device is set to a regular triangle. The distribution state of the cumulative light amount is shown at a distance of 1/4 of the width a of each lamp device. From this figure, it is understood that as the workpiece W moves, the amount of light accumulated in each area of the processed surface is accumulated. According to the triangular illuminance distribution formed by each of the lamp devices 40 A to 40 C, initially, the distribution of the cumulative light amount to the processed surface varies depending on the location, but when the rear end B of the workpiece W exceeds the original lamp device 40A That is, when the moving distance reaches (L + a) / 3, the amount of irradiation light in the entire field becomes uniform. Fig. 8 shows an embodiment in which the workpiece W is reciprocated by the same configuration of the lamp device as the previous embodiment.
