Specific embodiment

In the following, the embodiment of the utility model is illustrated referring to the drawings.Fig. 1 is to be denoted as the utility model An embodiment substrate board treatment 100 approximate vertical view.Fig. 2A, Fig. 2 B, Fig. 2 C are the actions for representing embodiment Summary side elevation.The substrate board treatment 100 possesses conveying robot 3 and thermal treatment unit 4.Upstream side unit 2 is to perform The unit for handling (pretreatment procedure) more more forwardly of than the processing in thermal treatment unit 4.Pretreatment procedure is, for example, coating process Process, transmission device transportation process etc..It should be noted that in Fig. 1 etc., X-Y plane represents horizontal plane, and Z-direction represents Vertical.

The substrate 5 received from upstream side unit 2 is carried to thermal treatment unit 4 by conveying robot 3.Substrate 5 is, for example, square The liquid crystal display device glass substrate of shape.In addition, substrate 5 or organic EL (Electro-Luminescence, Electroluminescent) display device glass substrate, display panel substrate used for solar batteries, PDP (Plasma Display Panel, etc. Gas ions display) use glass substrate or use in semiconductor manufacturing apparatus mask substrate etc..The length dimension example on one side of substrate 5 Such as it is more than 2m.

Conveying robot 3 possesses manipulator body 31, arm 32 and hand 33.Hand 33 is with flat-hand position supporting substrate 5. Hand 33 is divided into forked (comb teeth-shaped) of four for its front end.As shown in Figure 2 A, hand 33 has and is abutted with the back side of substrate 5 Multiple support portions 34.

Arm 32 is configured to stretch, circle round and lift.The substrate 5 supported by hand 33 is existed by the action of arm 32 It moves in horizontal plane, and is lifted in vertical.

Thermal treatment unit 4 is the heating processing unit for example heated to substrate 5.Thermal treatment unit 4 possesses chamber 41st, heating plate 42, fixed pin (proximity pin) 43 and lift-pin mechanism (not shown).Chamber 41 is to be formed in the interior thereof There is the substantially box shape of heat treatment space.The side of the chamber 41 opposite with conveying robot 31 forms opening.It is formed in the chamber The opening of room 41 mouth 7 and takes out of mouth as moving into for substrate 5.

Heating plate 42 is equipped in the inner bottom surface of chamber 41.Heating plate 42 is plate, and the size of its upper surface is set to compare The size of substrate 5 is larger.In the heat sources such as having heaters (not shown) built in heating plate 42.In the upper surface of heating plate 52 point It has been casually arranged with multiple fixed pins 43.Thermal treatment unit 4 heats the substrate 5 supported by multiple fixed pins 43 by heating plate 42. Heating plate 42 and multiple fixed pins 43 etc. are equivalent to the mounting portion of the utility model.It should be noted that it or is not provided with Fixed pin 43 and substrate 5 is directly positioned in the structure of the upper surface of heating plate 342.

Lift-pin mechanism (not shown) makes the front end of the multiple lift pins of insertion heating plate 42 compared with the upper of heating plate 42 It retreats in vertical direction on surface.Substrate 5 is handover to by heating plate 42 from conveying robot 31 by the lift-pin mechanism.

Electro-dissociator 6 is installed via bracket along the upper opening edge for moving into mouth 7 of chamber 41.Electro-dissociator 6 spray by The gas (hereinafter referred to as ionized gas) of ionization.Electro-dissociator 6 is, for example, pulse DC (Direct Current, direct current) Type applies DC voltage with predetermined time interval to a pair of positive/negative emitter, make each emitter generate respectively it is positive/negative from Son, also, the gas injection around each emitter spray the gas of ionization to defined direction.

Under pressurised conditions nitrogen or moisture-free, the air (purification air) of impurity are supplied to electro-dissociator 6.When so Nitrogen or purification air from the ejiction opening of electro-dissociator 6 spray when, ionize when being arranged on the electric discharge of electrode of electro-dissociator 6.

As shown in arrow in Fig. 2A etc., the injection direction that electro-dissociator 6 is configured to ionized gas is removing from chamber 41 Entrance 7 is towards the direction diagonally downward in chamber 41.In addition, electro-dissociator 6 is to the entire width side of substrate 5 along the X direction Injection ionized gas upwards.

Then, mainly the action of aforesaid substrate processing unit 100 is illustrated using Fig. 2A to Fig. 2 C.Fig. 2A is represented Conveying robot 3 from upstream side unit 2 receive substrate 5 after state by hand 33 towards 4 side of thermal treatment unit.Hand 33 exists Supporting substrate 5 on multiple support portions 34, and with chamber 41 to move into mouth 7 opposite.At this point, electro-dissociator 6 is to from moving into 7 direction of mouth The injection of direction diagonally downward ionized gas in chamber 41.

Fig. 2 B represent hand 33 via the state moved into the entrance chamber 41 of mouth 7.At this point, electro-dissociator 6 is to by removing Substrate 5 on the hand 33 of entrance 7 sprays ionized gas.The charged of the substrate 5 of ionized gas is injected with to obtain With so as to inhibit to generate electrostatic on substrate 5.

Fig. 2 C represent the multiple fixed pins 43 being handover to substrate 5 from hand 33 via lift-pin mechanism in heating plate 42 On state.So, in a state that substrate 5 is supported on multiple fixed pins 43, is carried out to substrate 5 stipulated time Heat.During this period, electro-dissociator 6 sprays ionized gas to the substrate 5 being supported on fixed pin 43.It is injected with The charged of substrate 5 of ionized gas is neutralized, so as to inhibit to generate electrostatic on substrate 5.

As described above, from shown in Fig. 2 B at the time of moving into action until the heating shown in Fig. 2 C at the time of until, Continue to spray ionized gas to substrate 5.In other words, electro-dissociator 6 is to the substrate 5 supported by hand 33 and subsequent by making The 5 sustained firing ionized gas of substrate loaded for the heating plate 42 of mounting portion.As a result, even if being large-scale substrate 5, Also it is charged that its can fully be inhibited.

After the defined time, the substrate 5 for completing to heat is handover to by hand 33 by lift-pin mechanism, is passed through It is taken out of by moving into mouth 7 (taking out of mouth) to outside chamber 41.At this point, electro-dissociator 6 is to the base passed through on the hand 33 for moving into mouth 7 Plate 5 sprays ionized gas.So, ionized gas also is sprayed to substrate 5 when taking out of, so as to further inhibit substrate 5 Upper generation electrostatic.

In the above-described embodiment, move into mouth 7 also to double as taking out of mouth, but can also will take out of mouth and separately be set with moving into mouth It puts.

Alternatively, it is also possible to be equipped with the heat treatment list for configuring coldplate to replace heating plate 42 to be cooled down to substrate 5 Member.That is, in Fig. 2A to Fig. 2 C, the structure represented by symbol 42 can be any one in heating plate, coldplate.Further The utility model can also be applied to the buffer cell for making substrate 5 temporarily standby in chamber 41 by ground.

Or the structure for configuring above-mentioned thermal treatment unit, buffer cell etc. in vertical multistage.
