Abstract
Description
特許文献1に記載の流体継手は、確かに上記の要望に適うものであり、大径ウエハを使用して同じ種類の半導体デバイスを大量生産するための近年の半導体製造装置や製造ラインに置いて数多く使用されている。一方で、最近、実用化も間近であるミニマルファブ(Minimal fab)という半導体製造装置・製造ラインが提案されている。
ミニマルファブの半導体製造装置・製造ラインにおいては、その個々の製造装置は幅294 mm×奥行き450 mm×高さ1440 mmというコンパクトな外形寸法に外観デザインを含めて規格統一が目指されており、操作画面などのユーザーインターフェース部も規格化され全装置で統一が図られている。そのため、ミニマルファブの半導体製造装置内の機器設置空間は極めて狭く、設置される機器は可能な限りのコンパクト化が要求され、且つ継手装着作業スペースは、十分確保できないという制約がある。そのため、確実なシール性を確保して小型化と狭い作業空間での作業性の更なる改良が望まれる。
本発明のもう一つの目的は、施工性及びシール性の双方に優れ、ミニマルファブ用の製造装置への適用に優れた管継手用の部品を提供することである。
本発明の更に別の目的は、上記菅継手部品を備えた流体制御器、流体制御装置、及び半導体製造装置を提供することにある。
本発明のもう一つ別な目的は、上記継手を使用して流体用機器を装置本体に付設する流体用機器の付設方法を提供することにある。

一端に第2フランジ部を有する第2管部材と、
前記第1管部材と前記第2管部材とを前記第1、2のフランジ部によりシール部を形成して接続するための筐体と押圧部材と、
を備えた管継手に使用される管継手用の部品であって、
前記筐体が、第1開口を有する第1端壁、該第1端壁と対向するとともに第2開口を有する第2端壁、及び前記第1端壁と前記第2端壁の間にあり第3開口を有する第1側壁を有し、内部に前記第1開口と前記第2開口とに連通するフランジ収容空間(1)と該フランジ収容空間に連通し前記押圧部材を収容する収容空間(2)とを備えており、
前記押圧部材が板状で弾性を備えており、
前記第1管部材は、前記第2開口から前記第1開口に向けて挿通されると前記第1フランジ部を前記フランジ収容空間に係止され、
前記第2管部材は、前記第2フランジ部から前記第2開口に挿通されると前記第2フランジ部を前記第1フランジ部に当接させた状態が形成されるとともに、前記押圧部材が前記第3開口から挿入されて前記空間(2)に収容されると、前記第2フランジ部は前記第1フランジ部に向けて押圧されて前記第1フランジ部と前記第2フランジ部との間をシールするシール部が形成される。
また、施工性及びシール性の双方に優れ、ミニマルファブ用の製造装置への適用に優れた管継手用の部品を提供することができる。
また、上記菅継手部品を備えた流体制御器、流体制御装置、及び半導体製造装置を提供することができる。
図1に示すように、管継手1は、流体通路2を形成する第1管部材4及び第2管部材6と、第1及び第2管部材4、6を収容して結合するための筐体8とを有している。第1及び第2管部材4、6、及び筐体8は何れも金属製である。第1及び第2管部材4、6は、それぞれ管継手1における外端(他端)4a、6aを形成している。
流体制御装置102は、ガス供給源110から供給されたガスを、流量等を調整して真空チャンバ106へ供給する装置であり、圧力計112、開閉弁114、116、MFC1~4などを備えている。流体制御装置102と真空チャンバ106との間には開閉弁118が設けられている。真空チャンバ106は、ウエハ120が載置される載置台122、ウエハ120上に薄膜を形成する電極124を備えている。真空チャンバ106には商用電源126が電気的に接続されている。排気手段108は、排気配管128、開閉弁130、集塵機132、真空ポンプ109を備えている。
また、各流体制御機器100間に、配管が介在する場合には該配管の各端部に、第1管部材4又は第2管部材6が構成される。
配管の各端部に第1管部材4又は第2管部材6を構成するには、配管の各端部に第1管部材4の外端4a又は第2管部材6の外端6aが溶接される場合や、他の継手構造を使用して接続される場合等がある。
管継手1及び開閉弁114、116、118、130は小型化が図られているため、各流体制御器100や配管が、管継手1を構成して接続されることにより、流体制御装置102の小型化を実現することができる。
図4に示すように、第1管部材4には、管継手1における内端(一端)4bに第1フランジ部16が形成されている。第1フランジ部16には流体通路2の開口縁に凹テーパ面16aが凹設されている。
第2フランジ部18には流体通路2の開口縁に凸テーパ面18aが凸設されている。
図6に示すように、筐体8は、第1端壁8a、第1端壁8aと対向する第2端壁8b、第1側壁8c、第1側壁8cと対向する第2側壁8dを備えた直方体状の小型の外形(例えば、図6で見たときの管径方向Yの長さ:約12mm、管長方向Xの長さ:約15mm、幅方向Zの長さ:約10mm)を有し、筐体8内には円柱状の空洞が形成されている。
また、筐体8の第1側壁8cには、押圧部材10が挿入される第3開口26が形成されており、第1フランジ部16が第1端壁8aに係止され且つ第2フランジ部18の凸テーパ面18aが第1フランジ部16の凹テーパ面16aに突き当てられて当接した状態で、押圧部材10が筐体8内に挿入されることで、押圧部材10が第2フランジ部18を押圧する。
押圧部10bは、その先端10b1から折曲部10cにかけて、対向する位置決め部10aとは反対側に凸に屈曲され、押圧部10bの幅方向に延びる屈曲線10b3が形成されている。
図10に示すように、押圧部材10は、収容空間(2)28に収容されたとき、位置決め部10a及び押圧部10bの幅方向Zの幅が各段差部28eを補完する形状を有する。即ち、第1内端面28aに当接する位置決め部10aの方が第2内端面28b側に位置する押圧部10bよりも幅方向Zの幅が小さくなる。
先ず、図13に示すように、管継手1の各構成部品を並べて配置する。このとき例えば、流体制御装置102内に、既に第1管部材4と筐体8が施工されている場合は、第2管部材6、座金12、ブッシュ14、押圧部材10を用意すれば良く、流体制御装置102内に、第2管部材6、座金12、ブッシュ14が既に施工されている場合は、第1管部材4、筐体8、押圧部材10を用意すれば良い。
次に、図15に示すように、座金12を第2管部材6に外嵌し、第2フランジ部18に当接させる。次に、図16に示すように、ブッシュ14を第2管部材6に外嵌する。
図19に示すように、上述の手順で組み立てて完成した管継手1では、位置決め部10a及び押圧部10bの各切り欠き10a2、10b2のU字状の底が第2管部材6に近接又は当接した状態で、位置決め部10aの先端10a1が第4開口30から突出している。
本実施形態では、押圧部材10を第3開口26から収容空間(2)28に収容したが、第4開口30から収容しても良い。この場合、位置決め部10aの先端10a1は、第3開口26から突出することになる。
また、図20に示すように、第2フランジ部18の凸テーパ面18aの管径方向Yを基準としたときの鋭角側の傾斜角αは、第1フランジ部16の凹テーパ面16aの管径方向Yを基準としたときの鋭角側の傾斜角βよりも大となっている。
尚、ここで言う線接触とは、純粋な幾何学的な線接触のみならず、弾性変形や塑性変形に伴うやや幅を持った接触も含む。
以上のように本実施形態によれば、施工性及びシール性の双方に優れ、ミニマルファブ装置への使用に好適であり、生産性及び信頼性の高い管継手1、この管継手1を用いた流体制御器、この流体制御器を用いた流体制御装置、及びこの流体制御装置を用いた半導体製造装置を提供することができる。
また、シール部36は、凹テーパ面16aに対し凸テーパ面18aが線接触した環状のシール線38により形成される。
例えば、上記実施形態では、第1フランジ部16に凹テーパ面16aを形成し、第2フランジ部18に凸テーパ面18aを形成している。しかし、これに限らず、シール線38が形成されれば良く、例えば、第1フランジ部16に凸テーパ面を形成し、第2フランジ部18に凹テーパ面を形成しても良い。
また、筐体8は上記実施形態の形状に限られない。例えば、図23に示すように、筐体8の第3側壁8eと第4側壁8fに収容空間(2)28に連通する切り欠き8e1及び8f1をそれぞれ設けることで、収容空間(2)28に収容された押圧部材10を専用治具等を使用してつかむことが可能であり、押圧部材10を挿入した面と同一の面から押圧部材10の取り外し作業ができ、作業性が向上する。
また、座金12やブッシュ14を備えない管継手1にも適用可能である。
また、図2では、半導体製造装置104がCVD装置である場合について説明したが、半導体製造装置104はスパッタリング装置又はエッチング装置であっても良い。エッチング装置(ドライエッチング装置)は、処理室、ガス供給手段(流体制御装置)、排気手段から構成され、反応性の気体による腐食作用によって材料表面などを加工する装置である。
