Definitions
- the present invention relates to a film formation method and a film formation apparatus particularly suitable for various film formation such as an optical thin film and a functional thin film.
- the characteristics as the final product are significantly deteriorated due to a slight decrease in the optical characteristics. Therefore, it is desired to improve optical characteristics (for example, light transmittance) for the optical thin film.
- membrane as an example of a functional thin film is known through the process shown below (patent document 1). In this method, first, a plurality of substrates to be processed are held on the entire surface of the substrate holding surface of the substrate holder, and then the substrate holder is rotated in a vacuum chamber.
- ions are continuously irradiated to all of the multiple substrates (irradiation of the entire surface of the ions), and then directed to all of the substrates on which surface irregularities are formed by ion irradiation.
- a film forming material made of a film forming raw material is evaporated and adhered (entire supply of the film forming material).
- the antifouling film is deposited on the uneven surface of all the plurality of substrates. According to this method, it is possible to form an antifouling film having abrasion resistance that can withstand practical use (paragraph 0029 of Patent Document 1).
- further improvement in abrasion resistance against the antifouling film is desired. It is rare.
- a film forming method and a film forming apparatus capable of further improving the performances of various thin films are provided.
- a film forming method and a film forming apparatus capable of efficiently forming an optical thin film with improved optical characteristics.

Abstract
Description
エネルギー粒子としては、イオン源によるイオンビームのほか、プラズマ源によるプラズマなどが例示される。
イオンなどのエネルギー粒子の照射を、回転している基体保持手段の一部領域のみに向けて行うことで、各基体に対してエネルギー粒子が時間的にパルス状に高密度で照射される。このパルス状に密度の高いエネルギー粒子の照射により、基体の表面のエネルギー状態の活性化が促進される。この後、多粒子間の相互作用を通して基体の表面は、熱平衡状態へと到達する(thermalization)確率が高くなる。これにより、上述した従来手法と比較して、基体表面に、諸性能(機能性薄膜における耐摩耗性、光学薄膜における光学特性)に優れた薄膜を形成することが容易となる。
成膜開始前の、エネルギー粒子の部分照射に続き、薄膜の成膜材料の供給を、回転している基体保持手段の一部領域のみに向けて行うことで、クリーニング後の各基体に対して薄膜の成膜材料が時間的にパルス状に高密度で照射される。このパルス状に密度の高い成膜材料の供給により、基体の表面のエネルギー状態の活性化促進に加え、基体表面に堆積する成膜粒子のエネルギー状態の活性化も促進され、基体の表面に堆積した成膜粒子が熱平衡状態へと到達する確率がより一層高くなる。その結果、基体表面に、諸性能(前出)に優れた薄膜を形成することがより一層容易になることが期待できる。
<<第1実施形態>>
図1に示すように、本例の成膜装置1は、縦置き円筒状の真空容器10を含む。
図4に示すように、測定位置によって測定点でのイオン電流密度が変動していることが理解できる。これは、基板ホルダ12が回転することによって軌跡上を移動する測定点について、測定位置によってイオンが照射されたり照射されなかったりしていることを意味している。この例の測定点は、イオンの照射が80°の位置から開始され、180°前後で最大密度を記録し、230°の位置で終了している。
図8に示すように、測定位置によって各測定点での成膜レートが変動していることが理解できる。これは、基板ホルダ12が回転することによって各軌跡上を移動する各測定点について、測定位置によって蒸発物が付着したり付着しなかったりしていることを意味している。なお、蒸発物が付着しているエリアは、図6の領域A3に相当する。
なお、図10に示す例において、基板ホルダ12の成膜面側の直径を「ドーム径D1」、基板ホルダ12の成膜面側の中心から蒸着源34の中心までの距離を「高さD2」、前記基準線から蒸着源34の中心までの最短距離を「オフセットD3」としたとき、一例として、D1を例えば1000mm~2000mm程度、D2を例えば500mm~1500mm程度、D3を例えば100mm~800mm程度に、それそれ設計することができる。
次に、成膜装置1を用いた成膜方法の一例(光学薄膜の成膜方法)を説明する。
本例では、光学薄膜の一例として、光学フィルター薄膜を成膜する場合を例示する。本例において成膜される光学フィルター薄膜は、高屈折率物質と低屈折率物質とを交互に積層させて成摸しているが、一種類若しくは複数種類の蒸発物質(成膜材料)からなる光学フィルターの成膜に対しても本発明は適用でき、その場合、蒸着源34の数や配置を適宜変更可能である。
cc/m」の略で、0℃、101.3kPa(1気圧)におけるものを示す。
Assisted Deposition method)を開始させる。このとき、ニュートラライザ40の作動も継続させる。すなわち、本例では、基板14の成膜面に対し、蒸着源34から成膜材料を飛散させる工程と、イオン源38から引き出される導入ガス(ここでは酸素)のイオンビームを照射する工程と、電子を照射する工程とが並行して行われる(成膜処理)。
この操作を所定回数繰り返すことにより多層膜を形成することができる。イオンビームの照射により基板14に電荷の偏りが生じるが、この電荷の偏りは、ニュートラライザ40から基板14に向けて電子を照射することで中和している。このようにして、基板14の成膜面に薄膜が所定厚みで形成される。
イオンビームの照射を、回転している基板ホルダ12の一部領域のみに向けて行うことで、各基板14に対してイオンビームが時間的にパルス状に高密度で照射される。このパルス状に密度の高いイオンビームの照射により、各基板14の表面のエネルギー状態の活性化が促進される。この後、多粒子間の相互作用を通して各基板14の表面は、高い確率で熱平衡状態へと到達し、これにより、イオンビームの全面照射を採用する従来手法と比較して、基板14表面に、諸性能(本例では、光学薄膜における光学特性)に優れた薄膜を形成することができる。
特に、T2がT1の半分以下となる(T2≦((1/2)・T1))ように基板ホルダ12の回転速度及びイオンの照射領域の一方又は双方を調整することで、こうした効果をより一層顕著に発揮させることができる。
イオンビームの部分照射に続き、成膜材料の供給を回転している基板ホルダ12の基体保持面の一部領域のみに向けて行うことで、クリーニング後の各基板14に対して薄膜の成膜材料が時間的にパルス状に高密度で照射される。このパルス状に密度の高い成膜材料の供給により、各基板14の表面のエネルギー状態の活性化促進に加え、各基板14表面に堆積する成膜粒子のエネルギー状態の活性化も促進され、各基板14の表面に堆積した成膜粒子がより高い確率で熱平衡状態へと到達し、これにより、各基板14の表面に、より一層、諸性能(本例では光学特性)に優れた薄膜を形成することができる。
特に、T4がT3の半分以下となる(T4≦((1/2)×T3))ように基板ホルダ12の回転速度及び成膜材料の供給領域の一方又は双方を調整することで、こうした効果をより一層顕著に発揮させることができる。
次に、成膜装置1を用いた成膜方法の他の例(機能性薄膜の成膜方法)を説明する。
本例では、機能性薄膜の一例として、有機物で構成される防汚膜を成膜する場合を例示する。なお、防汚膜は、撥水性、撥油性を有する膜であり、油汚れの付着を防止する機能を有する。ここで、「油汚れの付着を防止する」とは、単に油汚れが付着しないだけでなく、たとえ付着しても簡単に拭き取れることを意味する。すなわち、防汚膜は撥油性を維持する。
多孔質セラミック又は金属繊維又は細線の塊に疎水性反応性有機化合物を含浸させる場合、まず疎水性反応性有機化合物の有機溶媒溶液を作製し、浸漬法、滴下法、スプレー法等により溶液を多孔質セラミック又は金属繊維又は細線に含浸させた後、有機溶媒を揮発させる。疎水性反応性有機化合物は反応性基(加水分解性基)を有するので、不活性有機溶媒を使用するのが好ましい。
イオンビームの部分照射に続き、成膜材料の供給を回転している基板ホルダ12の基体保持面の一部領域のみに向けて行うことで、クリーニング後の各基板14に対して薄膜の成膜材料が時間的にパルス状に高密度で照射される。このパルス状に密度の高い成膜材料の供給により、各基板14の表面のエネルギー状態の活性化促進に加え、各基板14表面に堆積する成膜粒子のエネルギー状態の活性化も促進され、各基板14の表面に堆積した成膜粒子がより高い確率で熱平衡状態へと到達し、これにより、各基板14の表面に、より一層、諸性能に優れた薄膜を形成することができる。
特に、T4がT3の半分以下となる(T4≦((1/2)×T3))ように基板ホルダ12の回転速度及び成膜材料の供給領域の一方又は双方を調整することで、こうした効果をより一層顕著に発揮させることができる。
本例では、図1に示す成膜装置1(ただし規制板36を取り外した)を準備し、下記条件で成膜して防汚膜サンプルを得た。なお、本例のイオンビームの照射領域(A2)を基板ホルダ12に対する位置関係で示した様子を図11に示す。基板としてBK7(屈折率n=1.52)を用い、基板ホルダの回転速度(RS)を30rpmとした。
