Described cooling unit is arranged on the outside of body 110, by the refrigerating gases such as nitrogen are flowed into the inside of body 110 and cooling after the interior processed substrate 50 of chamber 111, is expelled to the outside of body 110.Described cooling unit comprises: import unit 160, supported by the left outer surface of body 110, import refrigerating gas to the inside of body 110; Deliverying unit 170, is supported by the right side outer surface of body 110, the inside that is directed into body 110 is expelled to the outside of body 110 with the refrigerating gas of cooling base 50.
Importing unit 160 comprises: ingress pipe 161, supported by the left outer surface of body 110, and enter for cooling gas flow; Exhaust nozzle 163, left end is communicated with ingress pipe 161, and right-hand member inserts the first supported hole 115 and is positioned at the inside of body 110, is expelled to the inside of body 110 from ingress pipe 161 receives refrigerating gas.
Now,, be communicated with and be provided with multiple exhaust nozzles 163 across interval along above-below direction on an ingress pipe 161 across being arranged at intervals with multiple ingress pipes 161 from the front side of body 110 to the direction of rear side.
The left outer surface of body 110 is combined with the first support 165, the first supports 165 supports the lower end of ingress pipe 161.Be specially, on the first support 165, be formed with through hole 165a, the lower end of ingress pipe 161 connects through hole 165a.And, on the outer peripheral face of the lower end of ingress pipe 161, be formed with the bonding pad 161a being combined on the first support 165.Because the first support 165 is combined on the left outer surface of body 110, and ingress pipe 161 is combined on the first support 165 by bonding pad 161a, and therefore, ingress pipe 161 is arranged on the left outer surface of body 110 securely.
Be combined with the first support component 167 that is formed with guiding in channel 167a in inside at the left outer surface of body 110.And the bottom of multiple ingress pipes 161 is supported by the first support component 167 respectively, and is communicated with respectively on guiding in channel 167a.
Because multiple ingress pipes 161 are interconnected by guiding in channel 167a, therefore, in the time that refrigerating gas is injected in the lower end to the first support component 167, refrigerating gas, by guiding in channel 167a, flows in each ingress pipe 161.Therefore, be convenient to inject refrigerating gas.In addition, the first support component 167 being bonded on body 110 due to ingress pipe 161 supports, and therefore ingress pipe 161 is set to more firm.
The left end of exhaust nozzle 163 is communicated with on ingress pipe 161, and right-hand member is inserted in the first supported hole 115.But if ingress pipe 161 is made up of rigid body completely, the tolerance during due to production and assembling, is difficult to exhaust nozzle 163 to be inserted in the first supported hole 115.In order to address this is that, on ingress pipe 161, be formed with pleated portions 161b.Thus, ingress pipe 161 can stretch or bending, has tolerance even if therefore import unit 160, also can easily exhaust nozzle 163 be inserted in the first supported hole 115.
Deliverying unit 170 comprises: discharge pipe 171, is supported by the right side outer surface of body 110, for discharging refrigerating gas; Gas absorption spray 173, left end is inserted in the second supported hole 117 and is positioned at the inside of body 110, and right-hand member is communicated with discharge pipe 171, sucks after flowing into the refrigerating gas of body 110 inside and is transported to discharge pipe 171.
Now, across interval, multiple discharge pipes 171 are set to the direction of rear side from the front side of body 110, on a discharge pipe 171, are communicated with multiple gas absorption sprays 173 are set across interval along above-below direction.
The right side outer surface of body 110 is combined with the second support 175, the second supports 175 supports the lower end of discharge pipe 171.At length say, on the second support 175, be formed with through hole 175a, the lower end of discharge pipe 171 connects through hole 175a.And, on the outer peripheral face of the lower end of discharge pipe 171, be formed with the bonding pad 171a being combined on the second support 175.Because the second support 175 is combined on the right side outer surface of body 110, and discharge pipe 171 is combined on the second support 175, and therefore, discharge pipe 171 is arranged on the right side outer surface of body 110 securely.
The right side outer surface of body 110 is combined with and is formed with second support component 177 of discharging runner 177a in inside.And the bottom of multiple discharge pipes 171 is supported by the second support component 177 respectively, and be communicated with respectively on discharge runner 177a.
Because multiple discharge pipes 171 are interconnected by discharging runner 177a, therefore, the refrigerating gas of discharging from multiple discharge pipes 171 is discharged from by the lower end of the second support component 177.Thus, be convenient to process the refrigerating gas of discharging.In addition, the second support component 177 being bonded on body 110 due to discharge pipe 171 supports, and therefore discharge pipe 171 is set up firmer.
The right-hand member of gas absorption spray 173 is communicated with on discharge pipe 171, and left end is inserted in the second supported hole 117.But if discharge pipe 171 is made up of rigid body completely, the tolerance during due to production and assembling, is difficult to gas absorption spray 173 to be inserted in the second supported hole 117.In order to address this is that, on discharge pipe 171, be formed with pleated portions 171b.Thus, discharge pipe 171 can stretch or bending, even if therefore deliverying unit 170 exists tolerance, also can easily gas absorption spray 173 be inserted in the second supported hole 117.
Because exhaust nozzle 163 and gas absorption spray 173 are positioned at the inside of the body 110 that keeps the condition of high temperature, be therefore likely subject to hot impact and damage.In order to prevent this phenomenon, exhaust nozzle 163 and gas absorption spray 173 are made up of quartz material respectively, and in addition, ingress pipe 161 and discharge pipe 171 are made up of metal material respectively.
But quartz and metal are difficult to mutually combine.Therefore, ingress pipe 161 and exhaust nozzle 163 are interconnected by the tube connector 169 being formed by synthetic resin, and discharge pipe 171 and gas absorption spray 173 are interconnected by the tube connector 179 being formed by synthetic resin.Now, be preferably, tube connector 169,179 is formed by the polytetrafluoroethylene (Polytetrafluoroethylene) of thermal endurance and chemical resistance excellence.
The refrigerating gas of discharging from exhaust nozzle 163 easily flow into body 110 inside.But the refrigerating gas that flow into body 110 inside is not easy to flow into the inside of gas absorption spray 173.Therefore the internal diameter that, is preferably gas absorption spray 173 is greater than the internal diameter of exhaust nozzle 163.
Between exhaust nozzle 163 and the first supported hole 115 and between gas absorption spray 173 and the second supported hole 117, certainly seal by seal member (not shown).
