- thermocouple T / C
- the leak port provided in the existing fluid control device is used as the temperature sensor insertion port.
- the diameter of the temperature sensor does not necessarily match the diameter of the leak port. For this reason, when the diameter of the temperature sensor is sufficiently smaller than the diameter of the leak port, it is necessary to fix the temperature sensor outside the leak port in order to prevent the temperature sensor from falling off the leak port. On the other hand, even if the leak port diameter is suitable for the temperature sensor diameter and the temperature sensor can be fitted into the leak port, the heat change is severe at the location where the leak port is provided. For this reason, the temperature sensor may fall off due to expansion and contraction.
- the fluid control device can be placed in various orientations, such as flat, vertical, and inverted, and the fluid control device itself vibrates or is affected by vibration from peripheral equipment such as a chamber.
- Fixing the sensor requires certainty that the temperature sensor can maintain thermal contact with the leak port in any orientation. Furthermore, in recent years where thinning of the thin film is required, such as the deposition method called ALD (Atomic Layer Deposition), which forms a thin film at the atomic or molecular thickness, there is a difference in fluid control equipment. Of course, it is necessary to ensure that there is no variation in fixing of each device even when fixing the temperature sensor.

- the main body 6 includes a valve body 61, an actuator body 62 disposed on the valve body 61, and a casing 63 disposed on the actuator body 62.
- the valve body 61 is provided with a flow path (not shown) through which a fluid flows and a leak port LP that can detect leakage of the fluid.
- the leak port LP is configured as a through hole having a length in the vertical direction of the fluid control device 3.
- One end of the leak port LP communicates with the outside, and the other end is shielded by the block-shaped joint 5 and is separated from the flow path by a sealing member such as a metal gasket.

- the length of the base portion 81 is a size equal to or smaller than the width of the valve body 61. This is a length that fits within the width of the gas line 2, and therefore the width of the gas line 2 is defined only by the width of the fluid control device 3, and not by the length of the sensor holding member 8.
- the width of the valve body 61 of this example shown in the figure is substantially the same in the length direction and the width direction. However, if the widths in the length direction and the width direction are different, the width in the short direction is set. The size fits.

Can be held. This also has the effect of preventing the temperature sensor 7 from falling off even when the fluid control device 1 is used in a state where it is tilted 90 degrees horizontally, for example.
- the through hole 8 a is formed in a direction slightly angled from a direction perpendicular to the mounting surface 831 of the base portion 81.
- an angle is formed in the length direction of the gas line 2 and away from the main body 6. Therefore, as shown in FIG. 7, the through-hole 8a and the leak port LP form a predetermined angle ⁇ in the length direction.

Abstract
Description
一方、リークポートの径が温度センサの径に適したものであり、リークポートに温度センサを嵌入させることができるような場合であっても、リークポートが設けられている箇所は熱変化が激しいため、膨縮により温度センサが脱落するおそれがある。また、流体制御機器は平置き、縦置き、逆置きなど、様々な向きで配置され得るし、流体制御機器自体が振動したり、チャンバ等の周辺設備から振動の影響を受けたりするため、温度センサの固定には、どの向きでも温度センサがリークポートとの熱接触を維持できる確実性が求められる。さらに、原子レベルや分子レベルの厚さで薄膜を形成するALD (Atomic Layer Deposition)という成膜方法が使われるなど、薄膜の一層の微細化が要求される近年においては、流体制御機器の機差を低減する必要があり、温度センサの固定においても当然、機器ごとの固定にばらつきがないようにする必要がある。
このような状況下においては、特許文献1に記載の流体制御装置のように、アクチュエータキャップの外周面上にサーマルセンサの支持部材を取り付けて横幅を広くしてしまうことは好ましくない。また、アクチュエータキャップに取付けられると、アクチュエータの動作時の振動の影響を受け易い。
図1は、本実施形態に係る流体制御機器3を備えた流体制御装置1を示している。流体制御装置1は、幅方向に隣接する複数のガスライン2(図1では3ライン)によって構成され、各ガスライン2がベース板金上に設置されている。
なお、以下の説明では、便宜的に図面上での方向によって部材等の方向を上下左右と指称することがあるが、流体制御装置1は仕様に応じて、図示上下左右の向きに設置されるため、特段の言及がない限り、指称する方向が本発明の実施あるいは使用の際の部材等の方向を限定することはない。
流体制御機器3は、図2及び図3に示されるように、本体6、温度センサ7、及びセンサ保持部材8によって構成される。
バルブボディ61には、流体が流通する流路(図示省略)と、流体の漏出を検知可能なリークポートLPが設けられている。
このリークポートLPは流路の近傍に設けられていることから、リークポートLP内の温度を測定することで、当該温度を流体の温度とみなすことができる。
この温度センサ7は、一端がリークポートLPに挿入されると共に、リークポートLPの内周面に当接し、これによりリークポートLP内の温度が測定される。
また、本例では温度センサ7として熱電対を用いたが、これに関わらず、リークポートLP内に挿入して温度を測定することができるものであれば、他の温度測定器具を用いることができる。
このセンサ保持部材8は図5及び図6に示されるように、リークポートLPの直上に配設される平板状の基体部81と、当該基体部81に設けられ、両端が開口した略筒状の貫通孔8aによって構成される。
また、センサ保持部材8はポリテトラフルオロエチレン(polytetrafluoroethylene, PTFE)等、耐熱性や耐薬品性を備えると共に、可撓性を有する樹脂素材からなるのが好適である。
なお、基体部81の形状は、図面上では平面視で略矩形状からなるが、これに限らず、取付面831が取り付けに必要な一定の面積を有していればよく、他の形状としてもよい。
なお、貫通孔8aの内径は温度センサ7の外径に対して締まり嵌めとなる径になっており、上面821側の開口部82から、取付面831側の開口部83へ温度センサ7を挿通させて保持することができる。また、これにより流体制御装置1が例えば横向きに90度傾けた状態で用いられる場合であっても、温度センサ7の脱落を防ぐ効果を有する。
角度θ>θmin=arctan(-ΔD/L)≒ΔD/L
を満たす必要があり、ΔD=0.4 L=14 である本実施例では、θmin=1.64[°]である。最低限必要な角度θminと比べて角度θを大きくするほど、復元力が大きくなり、温度センサ7の保持力が大きくなる。また、流体制御機器3の隣に設置される機器との干渉を防ぐために、温度センサ7は取付面831に垂直な向きに近い必要があり、θ<10[°]程度の値が望ましく、また、この範囲の角度θであれば温度センサ7として用いている熱電対の許容曲げRを満たすことができる。
これにより、温度センサ7がリークポートLPから脱落しにくい状態を維持しつつ、応力集中を防いで、温度センサ7が折れたり、センサ保持部材8がバルブボディ61から外れたりするのを防ぐことができる。
また、貫通孔8aの各開口部82、83近傍の周壁82aや凹溝83aにより、温度センサ7からセンサ保持部材8の貫通孔8aやリークポートLPの内周面に加わる応力の集中を回避し、温度センサ7の破損や、バルブボディ61からセンサ保持部材8が外れるのを防ぐことができる。
また、センサ保持部材8がバルブボディ61上に設けられることから、アクチュエータの動作に伴う振動の影響を受けにくい。
また、本例とは形状の異なるバルブにおいても、リークポートLP周辺にセンサ保持部材8の取付面831を確保できれば、本実施形態に係るセンサ保持部材8によってリークポートLPに温度センサ7を保持でき、汎用性が高い。
さらに、センサ保持部材8の長さは、バルブボディ61の幅以下のサイズからなるため、ガスライン2の幅がセンサ保持部材8の長さによって規定されることがなく、流体制御機器3の小型化に資する。これにより、温度センサ7とセンサ保持部材8を備えた本実施形態に係る流体制御機器3であっても、周辺に各種の部材が配設されてスペースの少ないチャンバ周辺に設置することも可能である。
