Description
最近では、LCDパネのサイズが大型化するにつれて、LCDサセプターのサイズも2m超過の水準にまで達している。よって、装備のメンテナンスのためには、サセプターの温度を低下させることが何よりも要求される。
現在、LCDサセプターの温度を325℃を基準として100℃に降温するまでかかる時間が、第5世代サセプターは8時間、第6世代サセプターは12時間、第7世代サセプターは18時間であるなど、LCDパネルのサイズが大型化するにつれて温度低下時間も相当多くかかる実情である。
このように温度低下に長時間がかかることは、装備のメンテナンスを難しくし、その結果として生産性の低下およびコストの損失を引き起こすという問題点として指摘されてきた。
また、ALN(Aluminum Nitride)ヒーターをそのまま使用する際には熱的衝撃(Thermal−shock)が激しいため、使用中または温度のアップ/ダウン時に破損してしまうなどの問題点があった。
また、費用の面でも、ALNヒーターの場合、300mmの製品が韓貨約8000〜9000万ウォンの水準であってかなり高価の製品群に属しており、経済的な負担が相当大きいという欠点も持っている。
かかる問題点を解決するために、前述したような金属ヒーターの代わりにALNヒーターを使用する技術が提案されているが、ALNは、高価の製品であるから、費用の面でメリットがないうえ、寿命が短いという問題点があった。
本発明の他の目的は、外部熱源を構成してALN母材のヒーター部材を加熱するようにして、実際ウエハーを加熱する効果を得ることを可能にすることにより、製造効率の向上を図った半導体製造装置を提供することにある。
第一に、現在LCDサセプターの温度を325℃から100℃に降温するまでかかる時間が、第5世代サセプターは8時間、第6世代サセプターは12時間、第7世代サセプターは18時間であるが、これに対し、本発明の冷却パイプが設置されたLCDサセプターは、50%以上の温度低下時間を節約することができるため、装備のメンテナンスが容易である。
第二に、装備のメンテナンスが容易であって、コストダウンおよび生産性の向上に寄与し、LCDパネルのサイズが大型化するにつれてさらに大きい効果が発揮される。
第三に、フッ素(Fluorine)などに対して強い材質であるALN(Aluminum Nitride)材質のヒーター部材を外部熱源によって発熱させることにより、簡単な構成によって半導体の製造効率を向上させることができる。
図1〜図3に示すように、本発明の冷却パイプが設置されたLCDサセプター10は、一定の厚さを持つサセプター本体11内に外部供給装置(図示せず)からの温度低下用冷気を供給する供給部21、および供給部21の入口から供給された冷気がサセプター10の内部を循環してから排出される排出部22が設けられ、サセプター本体11の全体にわたって冷気循環のために内設された断面円形の冷却パイプ20と、LCDを一定の温度に保つようにサセプター本体11を加熱するヒーター30とを含んでいる。
冷却パイプ20は第2カバー32によって覆われるように構成し、第2カバー32の上部には第3カバー33を設けることにより、冷却パイプ20を流れる冷気温度がヒーター30の発熱により急速に上昇することを防止する。
したがって、この冷気は、冷却パイプ20を介してサセプター10全体を循環しながらサセプター10の温度を低下させた後、排出部22を介して外部に排出される。
冷却パイプ20を流れる冷気によってサセプター10の温度が一定の温度以下に低下したと判断されると、装備のメンテナンスを行う。
図5および図6に示すように、本発明の半導体製造装置は、半導体製造工程中にガスを供給するシャワーヘッド40と、シャワーヘッド40からガスを受け取ってウエハー製造工程を行う工程チャンバー50と、工程チャンバー50でウエハー製造工程から発生するガスの排出ラインとして機能する真空ライン60と、工程チャンバー50における製造工程が行われたウエハーに対して、膜を蒸着(PE−CVD工程)させるために空気ポンピング機能を行う乾燥ポンプ70と、工程チャンバー50から真空ライン60に流入するガスの圧力を制御するように真空ライン60に取り付けられたスロットルバルブ61と、絶縁ゲートバルブ62とから構成された半導体製造装置において、工程チャンバー50内のウエハーヒーティング用加熱部材80にヒーティングガスを供給する外部発熱部材90と、外部発熱部材90にガスを供給するガス供給器100と、外部発熱部材90からヒーティングガスを受け取ってウエハーを加熱する加熱部材80とを含んでいる。
また、外部発熱部材90は、加熱部材80へのヒーティングガスの供給が行われるようにヒーティングガス流入ライン111を備える。
加熱部材80は、ALN材質から製造され、外部発熱部材90から供給される熱源(ヒーティングガス)を内部に流入させてから外部に排出する流路113が設けられる。
また、加熱部材80は金属材質、例えばSus、Inconel、銅などで製造される。
この際、加熱部材80の流路113内では、外部発熱部材90から流入ライン111を介して流入したヒーティングガスが循環しながら発熱してウエハーの加熱が行われる。流路113の循環を完了したヒーティングガスは外部に排出される。
すなわち、工程によるウエハーの温度がそれぞれ異なる点を勘案し、温度の均一性を維持するために流路113を様々な形で構成するのである。
