When substrate W is maintained on the pedestal 2, initiating signal is sent to the camera driving control device 22 of control gear 20 so that camera 4 moves to default reference position, simultaneously, make mobile carrying mechanism 3 move to the reference position, and utilize the telltale mark 2d of 4 pairs of pedestals 2 of camera to photograph, and make camera 4 move to the predeterminated position of substrate W, for example substrate edge part (or alignment mark (not shown)) is photographed, and view data is imported control gear 20 by view data input media 23, simultaneously, utilize position detecting device 24 to resolve the view data of being imported, thereby detect substrate position and pedestal position (detecting step S3).
When detecting the position of substrate W and pedestal 2, it is mobile according to separately position pedestal 2 to be calibrated, thereby makes mobile carrying mechanism 3 actions to carry out calibrating operation (calibration steps S4) by calibrating installation 25, mobile carrying mechanism driving control device 27 etc.In this calibrating operation, carry out substrate W and move in the calibration of θ direction, afterwards, when substrate W when X rectilinear direction and Y rectilinear direction move, make substrate W move to the relative position that can carry out laser beam irradiation and ultraviolet light irradiation.
Then, the calibrating position of the substrate W after the calibrating installation 25 of control gear 20 will be calibrated exports substrate position arithmetic unit 26 to, simultaneously, exports mobile carrying mechanism driving control device 27 to.In substrate position arithmetic unit 26, calculate shift position (laser begin irradiation position) and the translational speed (calculation step S5) of substrate W in laser beam irradiation according to the calibrating position data of the substrate W that sends here and the kind data that are stored in the substrate W in the memory storage 31.At this moment, also make substrate W rotation move 90 shift position and translational speeds when spending to carry out computing to described later.
When shift position that calculates substrate W and translational speed, by mobile carrying mechanism driving control device 27, first 3A of mobile guide mechanism (or second 3B of mobile guide mechanism) via mobile carrying mechanism, the pedestal 2 that keeps substrate W is gone up in X rectilinear direction (or Y rectilinear direction) is moved, thus be carried under the laser beam unit 5 precalculated position (for example reference position of the identification marking among the neighboring area Wc of substrate W) (S6).When substrate W is carried to the precalculated position, when substrate W is moved at a predetermined velocity, make 5 actions of laser beam unit, from each laser beam 5A, 5A, 5A illuminating laser beam, so that identification marking is exposed successively (laser beam irradiation step S7).
When illuminating laser beam, the translational speed of the mobile carrying mechanism 3 that substrate W moves and the exposure rate that laser beam is exposed are synchronously carried out.That is, make sound equipment optical element 7a (AOM) and Electronic Speculum unit 7c (Electronic Speculum) synchronous, thereby AOM make from the once light inflection of high speed shield and guarantee mark light, therefore can high-speed exposure.Therefore, when carrying out the irradiation of laser beam, substrate W does not stop, and can move with predetermined speed.
At this moment, this device 1 is in ultraviolet irradiation unit 9 sides, utilize control gear 20, the position data of the substrate W that sends here according to the kind data that are stored in the substrate W in the memory storage 31 with from mobile carrying mechanism driving control device 27, via travel mechanism 12 framework 9k is moved in the Y rectilinear direction, thereby the end avris of irradiation mouthful 9m is adjusted to and is positioned to cover the area of the pattern Wp of substrate W with the position (S8) (with reference to Figure 12 (a)) to neighboring area Wc side irradiates light.Meanwhile, exposure and identification mark M1 in the irradiation by laser beam and in the Wc of the neighboring area of substrate W, and when delivering to ultraviolet irradiation unit 9 sides, if the irradiation place of ultraviolet is the neighboring area Wc of substrate W both sides, then 20 pairs of irradiation areas adjustings of control gear shield mechanism 10 controls, make and do not use irradiation area to regulate the shield T1 of shield mechanism 10, and use shield T2, T3, thereby prepare to carry out all edge exposures.Then, when the beginning irradiation position of the ultraviolet of the actual arrival of substrate W ultraviolet irradiation unit 9, make the light path shield 9c of mechanism action, thereby use among shield T1, T2, the T3 any, with neighboring area Wc irradiation ultraviolet radiation light (ultraviolet irradiating step S10) substrate W
When the identification marking M1 on the X of the substrate W rectilinear direction and neighboring area Wc thereof are exposed, judge the neighboring area Wc of substrate W on X rectilinear direction (rectilinear direction) and this two direction of Y rectilinear direction (another rectilinear direction) finish (S11) (for example according to the operating state of the 3rd 3C of mobile guide mechanism) that whether expose to a plate base W, when being "No", in case be back to the mobile end on the X rectilinear direction or carry out mobile beginning of calibrating operation, move arbitrary place in terminal or mobile beginning at this and utilize the 3rd 3C of mobile guide mechanism of mobile carrying mechanism 3 that pedestal 2 is revolved to turn 90 degrees, thereby make substrate W rotation move 90 degree (S12).Then, by similarly carrying out the operation of step 6 (S6) as mentioned above, at the neighboring area of substrate W Wc exposure and identification mark M2, simultaneously to step 10 (S10), by remaining neighboring area Wc that exposes, and finish all edge exposures to all neighboring area Wc of substrate W.
When all edge exposures of substrate W finished, substrate W was by mechanical arm (not shown) taking out of oral-lateral (not shown) or taking out of (S13) from the oral-lateral of moving into of moving into substrate W from the mobile end side that is formed at substrate W.Then, move into new substrate W,, carry out the peripheral exposure operation of suitable substrate W by repeating each above-mentioned step S1~S13.
At this, the translational speed of pedestal 2 is described.
The mobile carrying mechanism driving control device 27 of control gear 20 is determined the translational speed of substrate W according to default irradiation energy.But sometimes if the zone of identification marking M is big, or the required exposure of photoresist China ink liquid is big, and then forming mark by laser beam unit 5 needs the time.In the case, mobile carrying mechanism driving control device 27 calculates laser beam unit 5 and forms the needed time of mark, to determine the translational speed Sa of substrate W.On the other hand, with the translational speed Sa of substrate W, all edge exposures of ultraviolet irradiation unit 9 have the situation of overexposure.Therefore, ultraviolet ray irradiation driving control device 29 receives the translational speed Sa of substrate W from mobile carrying mechanism driving control device 27.Then, irradiation area is regulated the position that shield mechanism 10 regulates width adjusting shadow shield 13a.
On the contrary, in photoresist China ink needed exposure of liquid and ultraviolet relation, the translational speed Sb of the substrate W when mobile carrying mechanism driving control device 27 is also determined ultraviolet irradiation unit 9 exposures.In the case, laser beam irradiation driving control device 28 receives the translational speed Sb of substrate W from mobile carrying mechanism driving control device 27.Intensity of laser beam is determined corresponding to translational speed Sb in laser beam unit 5 then.
For example, when the signal of sending here from mobile carrying mechanism driving control device 27 is translational speed Sa, regulate the irradiated area of shield mechanism 13 by ultraviolet ray irradiation driving control device 29 control irradiated areas corresponding to this translational speed Sa.Promptly, ultraviolet ray irradiation driving control device 29 for example preestablishes the arithmetic expression that just can become suitable exposure status corresponding to the great irradiated area of translational speed Sa, translational speed Sa substitution is somebody's turn to do in the default arithmetic expression to calculate irradiated area, and try to achieve the amount of movement (shift position) of width adjusting shadow shield 13a, thereby control width adjusting shadow shield moving part 13a from this operation result.
In addition, when the signal of sending here from mobile carrying mechanism driving control device 27 is translational speed Sb, laser beam irradiation driving control device 28 changes laser beam intensity by the light quantity that excites that changes laser beam source 5a, or change the integrated intensity of laser beam by the toggle frequency that changes laser beam, again or the modulation by sound equipment optical element 7a changes laser beam intensity, so that corresponding to translational speed Sb.And, corresponding to this translational speed Sb, by the reflection direction of the laser beam among the laser beam irradiation driving control device 28 control Electronic Speculum unit 7c, so that corresponding to translational speed Sb.
So, laser beam irradiation driving control device 28 is constituted as corresponding to the translational speed of substrate W with ultraviolet ray irradiation driving control device 29 and moves.And, under the translational speed Sa situation identical, in each unit 5,9, control, to carry out exposure operation by the action that is set to benchmark with translational speed Sb.
Then, with reference to Figure 12 and Figure 13, specifically the situation at the neighboring area Wc of substrate W exposure describes.Promptly, shown in Figure 12 (a) and (b), irradiation area is regulated shield mechanism 10 and is utilized shield mobile device 10A via slide mechanism 10A5 shield T2 to be positioned on the Y rectilinear direction, and to make the position of the shielding portion t2a of shield T2 be to be overlapped on the position of identification marking M1 to carry out the position of shading.And at this, shielding portion t2a is mounted in advance with identification marking M1, M2 has area identical.If the neighboring area Wc of substrate W approaches irradiation mouthful 9m, then ultraviolet irradiation unit 9 makes the light path shield 9c of mechanism action, makes shadow shield 9c1 move in the mode of keeping out of the way from light path, thereby the ultraviolet illumination of the lamp of self discharge in the future 9a side is incident upon neighboring area Wc.
Then, after the position of identification marking M1 is sent here along with moving of substrate W, the shielding portion t2a of locational shield T2 that is overlapped in this identification marking is with the synchronous speed of the translational speed of substrate W, move in the mode of crossing irradiation mouthful 9m, thereby under the state that covers identification marking M1, by carrying out all edge exposures at remaining neighboring area Wc irradiation ultraviolet radiation light.
In addition, shown in Figure 12 (c), in the Wc of the neighboring area of substrate W, because follow-up identification marking M1 is continuous with irradiation mouthful 9m, so shield T3 and shield T2 similarly be positioned at identification marking M1 position overlapped on, and by synchronously moving with the translational speed of substrate W under the state that covers follow-up identification marking M1, to remaining neighboring area Wc irradiation ultraviolet radiation light to carry out all edge exposures.
And, shown in Figure 12 (d), cross irradiation mouthful 9m and the shield T2 that covers identification marking M1 moves on the direction opposite with substrate W moving direction at high speed with predetermined timing, thereby crossed an irradiation mouthful 9m once again.And, though carry out the exposure operation of the neighboring area Wc of substrate W this moment, be high-speed mobile, so do not hinder for the exposure operation of neighboring area Wc owing to cross when shining mouth 9m.Then, shield T2 is with previous described roughly the same, be positioned with the 3rd position that identification marking M1 overlaps on, and cross an irradiation mouthful 9m, thereby identification marking M1 covered and other neighboring area Wc is exposed by moving with the translational speed identical with substrate W.
So, irradiation area is regulated shield mechanism 10 when utilizing shield T2, T3 to cover (shading) identification marking, moving and crossing irradiation mouthful 9m with the translational speed identical with substrate W, and during corresponding to follow-up identification marking, high-speed mobile on the direction opposite repeatedly with substrate W moving direction, crossing an irradiation mouthful 9m, thereby even the quantity increase of identification marking M1 (M2) also can tackle.
In addition, shown in Figure 13 (a)~(d), when there is area of the pattern in the both sides at the neighboring area of substrate W Wc, shield T1 and shield T2, T3 are used, to tackle.
Shown in Figure 13 (a), at first, via travel mechanism 12 framework 9k is moved on the Y rectilinear direction, thereby an end that will shine mouthful 9m is adjusted on the position of the area of the pattern Wp that can cover substrate W.Then, when using shield T1, make the second framework 10B1 move to the precalculated position, and carry out shield T2, the T3 location on the Y rectilinear direction along slide mechanism 10A5.And, via Y direction mobile device 10D, shield T1 is moved on the Y rectilinear direction, and send to the position that can cover area of the pattern Wp, cover with the preset width on the Y rectilinear direction of contrast loophole 9m, make light can't expose on the area of the pattern Wp of opposition side of neighboring area Wc.
Then, under the state of the irradiated area that reduces irradiation mouthful 9m by shield T1, use shield T2, T3, and as illustrated among Figure 12 (b)~(d), when covering identification marking M1 to neighboring area Wc exposure, thereby carry out disposing all edge exposures under the state of area of the pattern Wp in the both sides of neighboring area Wc.And the control of irradiation area adjusting shield mechanism 10 is suitably carried out according to the kind data of substrate W and the position data of substrate W by the ultraviolet ray irradiation driving control device 29 of control gear 20.
When the identification marking M1 on the X of the substrate W rectilinear direction and neighboring area Wc thereof are exposed, judge the neighboring area Wc of substrate W on X rectilinear direction (rectilinear direction) and this two direction of Y rectilinear direction (another rectilinear direction) finish (S11) (for example according to the operating state of the 3rd 3C of mobile guide mechanism) that whether expose to a plate base W, when being "No", in case be back to the mobile end on the X rectilinear direction or carry out mobile beginning of calibrating operation, move arbitrary place in terminal or mobile beginning at this and utilize the 3rd 3C of mobile guide mechanism of mobile carrying mechanism 3 that pedestal 2 is revolved to turn 90 degrees, thereby make substrate W rotation move 90 degree.Then, by similarly carrying out the operation of step 6 (S6) as mentioned above, at the neighboring area of substrate W Wc exposure and identification mark M2, simultaneously to step 10 (S10), by remaining neighboring area Wc that exposes, and finish all edge exposures to all neighboring area Wc of substrate W.
When all edge exposures of substrate W finished, substrate W was by mechanical arm (not shown) taking out of oral-lateral (not shown) or take out of from the oral-lateral of moving into of moving into substrate W from the mobile end side that is formed at substrate W.
And, according to the kind of substrate W, the substrate that does not form identification marking at the Centromedian neighboring area Wc of substrate W shown in Figure 3 is also arranged, in the case, in Figure 13, only utilize shield T1 to cover the light of the irradiation mouth 9m on the Y rectilinear direction and finish all edge exposures.
And, according to the kind of substrate W,, as shown in Figure 3, be the state of no identification marking M2 when revolving when turning 90 degrees.In the substrate W of so no identification marking M2, do not use laser beam and only use the ultraviolet irradiation of ultraviolet irradiation unit 9 sides, therefore pass through location by the framework 9k of travel mechanism's 12 realizations, and irradiation area regulates the location of the shield 1 of shield mechanism 10, can carry out the exposure operation of ultraviolet.Therefore, control gear 20 utilizes the kind data of substrate W to control, and makes the translational speed of substrate W become the initial conditions of substrate W.So, owing to be the state that does not have identification marking M2, so revolving the translational speed of the substrate W when turning 90 degrees is to be set under state as described below, that is: in irradiation mouthful 9m, the irradiated area of being regulated 13 realizations of shield mechanism by irradiated area becomes maximum state, from being configured to improve the efficient of exposure operation.

This device 1 utilizes the 11b of travel mechanism of illumination photometry portion of measuring appliance 11 that the 11a of illumination photometry portion is moved to from retreating position and locates, and is located under the irradiation mouthful 9m.Then, this device 1 makes the shadow shield 9c1 action of the light path shield 9c of mechanism, and from irradiation mouthful 9m illumination measurement section 11a is carried out rayed to measure the illumination of light.Then, the result after the mensuration delivers to ultraviolet ray irradiation driving control device 29 from the measurement mechanism 30 of control gear 20, so that discharge lamp 9a is carried out the adjusting of curtage, thereby regulates illumination.
Even this device 1 is in laser beam unit 5, substrate W is not on the position of illuminating laser beam the time, utilize CCD photographic element 6b and power meter 6c or power meter 8a and CCD photographic element 8b to carry out the status adjustment of laser beam, for example carry out the adjusting of laser beam source 5a, the adjusting of sound equipment optical element 7a, or more than in the adjusting of beam expander 8c any one, thereby make laser beam be always maintained at proper state.
And as shown in figure 14, the structure of the also available laser beam of this device 1 unit 15 replaces laser beam unit 5.Figure 14 is the side view of other structure of laser beam unit.And, in the structure of optical path length regulon 6,, therefore omit its explanation with not variation of structure shown in Figure 5.
The laser radiation unit 17 of laser beam unit 15 (herein being three) forms with identical structure respectively, thereby forms from the structure of optical path length regulon 6 via optical fiber 15a transmission laser bundle.
