When the substrate S is seated on the inverted protrusion 321 as the inverted protrusion 321 protrudes from the inverted supporter 320, the transfer unit 200 is stabilized between the inverted supporter 320 and the substrate S To be inserted.

FIG.

Referring to FIGS. 7 to 10, the twist unit 400 is provided in the inversion unit 300 to fix the connection line 450 for connection with the inversion unit 300. Here, the connection line 450 may include at least one of a cable for electrical connection and a fluid line for fluid movement.

The torsion unit 400 may suppress or prevent line twist of the connection line 450 and may omit the installation of cable bails for unifying the connection lines 450, The connection line 450 can be prevented from being detached or damaged by the cable bare.

The torsion unit 400 may further include a torsional penetration portion 410 and a torsional fixation portion 420 and may further include at least a torsion support portion 423 among the torsion support portion 423 and the torsion socket portion 425 .

The torsional penetration portion 410 is provided in the reversing unit 300 so that the connection line 450 is passed.

The torsional penetration portion 410 may include a first bracket portion 411, a second bracket portion 412, and a torsion bearing portion 413.

The first bracket part 411 forms a center of rotation when the substrate S supported by the inverting support part 320 is reversed. The first bracket part 411 is formed as a hollow body so that the connection line 450 is passed therethrough.

The second bracket part 412 is rotatably coupled to the first bracket part 411 according to the operation of the reversing unit 300. The second bracket portion 412 is formed as a hollow body so that the connection line 450 is passed therethrough.

Here, it is advantageous that the first bracket part 411 and the second bracket part 412 are formed to overlap each other.

The torsion bearing portion 413 rotatably supports the second bracket portion 412 between the first bracket portion 411 and the second bracket portion 412.

It is possible to prevent the connection line 450 from interfering with the inversion unit 300 when the substrate S is inverted according to the configuration of the twist unit 400. [

For example, the first bracket part 411 may be provided in the inverting shaft part 330 or the swing bracket part 375 in the reversing unit 300 and may be rotated in accordance with the reversing operation of the substrate S, The first bracket portion 412 does not interfere with the rotation of the first bracket portion 411.

The second bracket portion 412 may be provided in the inverting shaft portion 330 or the swing bracket portion 375 of the reversing unit 300 so as to be rotated in accordance with the reversing operation of the substrate S, The first bracket portion 412 does not interfere with the rotation of the first bracket portion 411.

[

The connection line 450 may include a 180 degree or 360 degree twist between the first fixing part 401 and the second fixing part 402 in accordance with the normal rotation angle of the reversing unit 300 for reversing the substrate S. [ .

The connecting line 450 may be formed by twisting the first and second fixing units 401 and 402 in opposite directions from each other in accordance with the forward and reverse rotation angles of the reversing unit 300 for reversing the substrate S. [ .

Accordingly, the torsion of the connection line 450 becomes 180 degrees or 360 degrees, which is the normal and reverse rotation angles of the inversion unit 300, to a maximum of half such as 90 degrees or 180 degrees, so that the stress applied to the connection line 450 And extend the lifetime of the connection line 450. [0054]

For example, if the normal rotation angle of the reversing unit 300 is 180 degrees, the connection lines 450 may be linearly connected to the first fixing portion 401 and the second fixing portion 402 without twisting the connection line 450, And then operating the inversion unit 300, the connection line 450 can be twisted 180 degrees.

In this case, the twist angle of the connection line 450 may be twisted within a range of 0 to 180 degrees.

The connecting line 450 may have a center or torsional penetration portion 410 between the first fixing portion 401 and the second fixing portion 402 as a reference The connection line 450 is twisted by 90 degrees and fixed on the first fixing part 401 side and the connection line 450 is fixed by twisting by 90 degrees on the second fixing part 402 side, So that they are twisted in the directions opposite to each other on the side of the fixing portion 401 and the side of the second fixing portion 402. Accordingly, when the inversion unit 300 is operated, the connection line can be twisted within a range of 90 degrees in the forward direction from 90 degrees in the reverse direction.

In this case, the twist angle of the connection line 450 is reduced on the basis of the linear 0 degree of the connection line 450, thereby reducing the stress applied to the connection line 450 and extending the life of the connection line 450 .

[ In addition, the twist coupling portion 422 can fix the twist-gathering portion 421 in the second fixing portion 402 so as to face the first fixing portion 401. The torsional coupling part 422 can fix the torsion collecting part 421 to the reversing body part 310 of the reversing unit 300 at the second fixing part 402. [

However, when the process pressure is 0.01 mTorr or less, the process gas is difficult to be converted into the form of a complete gas cluster, and the process gas may be increased in speed and the processing operation of the substrate may become poor.

Also, if the process pressure is greater than 50 torr, the process gas may not be fully converted into a gas cluster form, excessive process gas input may result in damage to the pumping portion, and the effectiveness of substrate cleaning may be reduced.

Then, the process gas is supplied to the nozzle unit 563 via the process line unit 562 according to the operation of the process pumping unit 561, and is converted into a gas cluster form at the nozzle unit 563 and discharged.

In addition, the heat exchanging unit 565 can adjust the temperature of at least one of the accommodation space 531 and the nozzle unit 563 within a temperature range of minus 75 degrees or more and 0 degrees or less.

Accordingly, the process gas can be stably converted into a gas cluster shape in the nozzle unit 563, and the distance between the nozzle unit 563 and the substrate S that is moved up and down can be easily adjusted.

However, when the adjustment temperature range is larger than the upper limit value, the process gas is hardly completely converted into the form of a gas cluster, the process pressure of the process gas in the nozzle portion 563 is increased with the expansion of the process gas, And the substrate S to be moved up and down.

Further, when the adjustment temperature range is lower than the lower limit value, the process gas is difficult to be completely converted into the form of a gas cluster, the process pressure of the process gas must be increased along with the condensation of the process gas, It is difficult to adjust the distance between the nozzle portion 563 and the nozzle portion 563 and the nozzle portion 563 may be freezing in the accommodation space 531 and the nozzle portion 563 may be clogged or broken by freezing.

Further, the present invention can stably maintain the flatness of the substrate S when the substrate S is transferred or inverted.

Further, the present invention can prevent the outer shape of the substrate S from being deformed when the substrate S is adsorbed, and prevent the occurrence of unevenness (mura) on the surface of the substrate S.

The present invention also facilitates the inversion of the substrate S and prevents the protrusion of the substrate S (oscillation of the substrate S) transmitted to the inversion unit 300, It is possible to prevent the substrate S from being damaged by the substrate W.

In addition, the present invention can prevent the twist of the connection line 450 for connection with the inversion unit 300 in the inversion operation of the substrate S through the inversion unit 300.
