Abstract
Description
本願は、2022年4月27日に、日本に出願された特願2022-073579号に基づき優先権を主張し、その内容をここに援用する。
例えば、プラズマ処理装置に用いられる電極板としては、シリコン板材に複数の通気孔が形成された構造を有するシリコン部材が使用されている。
例えば、特許文献1においては、シリコン製の複数の板状電極部材を厚さ方向に接合したシリコン電極板が開示されている。
本発明の態様2のシリコン部材によれば、前記接合層中のSi相のアスペクト比が3.0以下とされているので、高温環境下で使用した場合であっても接合層の破損を抑制することができ、耐熱性に特に優れている。
本発明の態様3のシリコン部材によれば、前記接合層がAlまたはAlを含有する金属で構成されているので、Si含有材料からなる複数の板状部材を厚さ方向に確実に接合することができる。
本発明の態様4のシリコン部材によれば、前記接合層が、Siの含有量が0.5mass%以上12.6mass%以下の範囲内のAl-Si合金で構成されているので、Si含有材料からなる複数の板状部材を厚さ方向に確実に接合することができる。また、接合層におけるSi相の面積率が12%以下に抑制されているので、高温環境下で使用した場合であっても接合層の破損を抑制することができ、耐熱性に特に優れている。
本発明の態様5のシリコン部材によれば、前記シリコン部材の厚さ方向に延在する仮想線に沿って線分析した際に、前記仮想線上におけるSiピークとAlピークとの交点の数が、接合層において4以下とされているので、接合層中に存在するSi相の数が少なく、高温環境下で使用した場合であっても接合層の破損を抑制することができ、耐熱性に特に優れている。
また、前記加圧および加熱工程において液相がほぼ生じることがなく、接合材のはみだしを抑制できるとともに、接合層に引け巣やボイドが形成されることがなくなり、接合強度を向上させることができる。
本発明の態様7のシリコン部材の製造方法によれば、前記接合材が、AlまたはAlを含有する金属で構成されているので、Si含有材料からなる複数の板状部材を確実に接合することができる。
本発明の態様8のシリコン部材の製造方法によれば、前記接合材が、Siの含有量が0.5mass%以上12.6mass%以下の範囲内のAl-Si合金で構成されているので、板状部材から接合層へのSiの拡散を抑制でき、接合層におけるSi相の面積率を十分に低くすることができる。
本実施形態であるシリコン部材においては、例えば、半導体デバイス製造プロセスに使用されるプラズマエッチング装置やプラズマCVD装置等のプラズマ処理装置において、チャンバー内に配設されるシリコン部材であり、本実施形態では、シリコン板材に複数の通気孔が形成された構造を有するシリコン電極板とされている。すなわち、本実施形態のシリコン部材においては、使用によって損耗した複数のシリコン電極板を貼り合わせ、再生シリコン電極板として利用するものである。
そして、本実施形態であるシリコン部材10は、図1A、図1Bに示すように、第1板状部材11と第2板状部材12とが厚さ方向に接合された構造とされており、第1板状部材11と第2板状部材12との間には、接合層20が形成されている。
そして、第1板状部材11と第2板状部材12との間に形成された接合層20におけるSi相25の面積率が12%以下とされている。
なお、接合層20におけるSi相25の面積率は10%以下であることがさらに好ましく、8%以下であることがより好ましい。接合層20におけるSi相25の面積率の下限値は、特に限定されないが、0%以上であることが好ましい。
本実施形態では、接合層20におけるSi相25の面積率は、シリコン部材10の積層方向に沿った接合層20の断面における面積率である。
なお、接合層20におけるSi相25のアスペクト比は2.5以下であることがさらに好ましい。接合層20におけるSi相25のアスペクト比の下限値は、特に限定されないが、1.0以上であることが好ましい。接合層20におけるSi相25の形態は、球形状が好ましい。
なお、接合層20は、Siの含有量が0.5mass%以上12.6mass%以下の範囲内のAl-Si合金であることが好ましい。さらに、接合層20は、Siの含有量が0.5mass%以上8.0mass%以下の範囲内のAl-Si合金であることがさらに好ましい。
このとき、図2に示すように、Siピークは、第1板状部材11、第2板状部材12および接合層20中のSi相25を示すことになる。また、Alピークは、AlまたはAlを含有する金属で構成された接合層20を示すことになる。
よって、第1板状部材11と接合層20との境界、および、第2板状部材12と接合層20との境界についても、接合層20におけるSiピークとAlピークとの交点となる。
仮想線P上におけるSiピークとAlピークとの交点の数の下限値は、特に限定されないが、2以上であることが好ましい。
本実施形態では、図4に示すように、使用済のシリコン電極板を2枚準備する。
そして、シリコン電極板の表面(プラズマ面)を研削盤40によって研削する。これにより、第1板状部材11および第2板状部材12を得る。なお、プラズマ面を研削することにより、使用による損耗によって拡径した通気孔のプラズマ面側の部分が除去されることになる。
次に、第1板状部材11および第2板状部材12の接合面に、それぞれAl層21を形成する。
なお、Al層21の形成方法に特に制限はなく、蒸着やスパッタリング法などの既存の各種方法を適宜選択することができる。本実施形態では、Alスパッタリングターゲットを用いたスパッタリング法によってAl層21を形成している。
Al層21の厚さは、0.05μm以上2μm以下の範囲内とすることが好ましい。
次に、第1板状部材11および第2板状部材12を互いのAl層21,21が対向するように配置するとともに、対向するAl層21,21に接するように接合材35を配置し、第1板状部材11と接合材35と第2板状部材12との積層体を形成する。
ここで、接合材35としては、AlまたはAlを含有する金属で構成されていることが好ましい。本実施形態では、接合材35として、Siの含有量が0.5mass%以上12.6mass%以下の範囲内のAl-Si合金を用いることが好ましい。
次に、積層体を積層方向に加圧した状態で加熱し、第1板状部材11および第2板状部材12を、接合層20を介して接合する。なお、第1板状部材11および第2板状部材12の接合面に形成されたAl層21,21は、加圧および加熱工程S04の加熱時に接合層20内に取り込まれることになる。
本実施形態において、接合材35として、Siの含有量が0mass%以上12.6mass%以下の範囲内のAlまたはAl-Si合金を用いる場合には、保持温度は500℃以上650℃以下の範囲内とすることが好ましい。また、本実施形態において、第1板状部材11および第2板状部材12の接合面に形成したAl層21を用いて接合する場合(Al層21を接合材とする場合)には、保持温度は500℃以上650℃以下の範囲内とすることが好ましい。
なお、接合材35として、Al、または、Siの含有量が0.5mass%以上12.6mass%以下の範囲内のAl-Si合金を用いる場合には、保持温度の下限を550℃以上とすることがさらに好ましく、580℃以上とすることがより好ましい。また、保持温度の上限を640℃以下とすることがさらに好ましく、600℃以下とすることがより好ましい。
なお、保持時間の下限は、1.5時間以上とすることがさらに好ましく2時間以上とすることがより好ましい。また、保持時間の上限は、8時間以下とすることがさらに好ましく、6時間以下とすることがより好ましい。
なお、積層方向の加圧荷重の下限は、0.03MPa以上とすることがさらに好ましく、0.1MPa以上とすることがより好ましい。また、積層方向の加圧荷重の上限は、8MPa以下とすることがさらに好ましく、6MPa以下とすることがより好ましい。
また、加圧および加熱工程S04において多量の液相が生じることがなく、接合材35のはみだしを抑制できるとともに、接合層20に引け巣やボイドが形成されることがなくなり、接合強度を向上させることができる。
例えば、本実施形態では、シリコン部材は、使用済の2枚のシリコン電極板を接合することで形成された再生シリコン電極板としたものとして説明したが、これに限定されることはなく、シリコン部材は、Si含有材料からなる板状部材同士が接合されたものであればよく、3つ以上の板状部材が接合されたものであってもよい。
シリコン部材が3つ以上の板状部材を具備する場合、厚さ方向に延在する仮想線上におけるSiピークとAlピークとの交点の数は、2つの板状部材とそれらの間に形成された1つの接合層との範囲内で測定された数である。
準備した板状部材と接合材と板状部材を積層した積層体を形成した。この積層体に対して表1に示す条件で加圧および加熱することにより2枚の板状部材を接合し、接合層を有する各種シリコン部材を製造した。
得られたシリコン部材について、以下のように評価した。評価結果を表2に示す。
SEM-EDS装置(エネルギー分散型X線分析装置が搭載された走査型電子顕微鏡)を用いて、シリコン部材の積層方向に沿った断面を観察し、その断面における接合層を5000倍の視野で、Siと接合層を構成する元素(以下、接合層元素)のマッピング分析を行った。各マッピング結果について、SEM-EDS装置の付属ソフトの定量マップ機能を用いて各ピクセル毎に、Siと接合層元素のみがいると仮定した半定量計算を行い、それぞれのピクセル毎の含有量(重量%)を示す定量マップを作成した。作成された定量マップを基に視野内の接合層におけるSi含有量が99mass%以上の相をSi相とし、視野内の接合層におけるSi相の面積率を算出した。
視野のうち接合層の輪郭内のSi相の面積率を算出した。算出に用いた視野は複数であり3視野(3画像)で、面積率はそれらの平均値とした。なお、観察倍率は、接合層の上下の界面が視野内に入る倍率を選択すればよい。
ここで、本発明例1の観察結果(SEMの断面組織)およびマッピング結果を図5A~図5Cに示す。本発明例6の観察結果(SEMの断面組織)、元素の線分析結果、マッピング結果を図6A~図6Dに示す。比較例1の観察結果(SEMの断面組織)、元素の線分析結果、マッピング結果を図7A~図7Dに示す。
上記で求めたSi相のアスペクト比を、市販の画像解析ソフト(WIN Roof)を用いて算出し、その平均値を求めた。
観察されたSi相の最も長い寸法を長軸長さとし、この長軸に直交する方向で最も長い寸法を短軸長さとし、アスペクト比は、長軸長さ/短軸長さとした。
得られたシリコン部材の積層方向に沿った断面を観察し、その断面における接合層についてSEM-EDS分析(元素の線分析)を行い、接合層を含む断面に接合層の厚さ方向に延在する仮想線を引き、この延在する仮想線上においてAlピークとSiピークとの交点の数をカウントした。なお、本発明例6と比較例1のSEM-EDSによる線分析結果は、図6B、図7Bにそれぞれ示した。
得られたシリコン部材の外観を目視観察し、接合材のはみ出しの有無、および、割れの有無を評価した。接合材のはみ出しと割れが確認されたものを「D」(poor)と表記した。接合材のはみ出しはあるが割れがないものを「C」(fair)と表記した。接合材のはみ出しと割れが確認されなかったものを「B」(good)と表記した。
図8A~図8Cに示すように、得られたシリコン部材を10mm角に切り出し、板状部材の接合面とは反対側の面をそれぞれ引張試験治具に接着剤を用いて接合した。そして、万能引張試験機にセットし、0.1mm/minの速度で引張試験を実施した。なお、接着剤による板状部材と引張試験治具との接合強度である15MPaを超える場合は「15MPa以上」と表記した。
得られたシリコン部材を300℃で24時間保持し、その後の外観を目視観察し、割れや剥がれの有無を確認した。また、割れや剥がれが目視で観察できなかったものについては、300℃で加熱の前後に超音波探傷検査を実施した。確認した結果、割れや剥がれが確認されたものを「D」(poor)と表記した。割れや剥がれが確認されなかったものの内、超音波探傷像の変化(接合率の変化)が有ったものを「B」(good)と表記した。超音波探傷像の変化(接合率の変化)が無かったものを「A」(excellent)と表記した。
