前記第一工程での加熱温度を、前記半導体膜に結晶核が発生する温度の50%以上100%未満となるように調整することを特徴とする半導体装置の製造方法。
このように、前記構成によれば、耐熱性に優れ、且つ、高温に晒されたとしても寸法変化が少ない基材フィルムを用いるため、製造時に高温に晒されたとしても、半導体膜が基材フィルムから剥離してしまうことを抑制することができる。
図1は、本発明の一実施形態に係る半導体装置100の模式断面図である。半導体装置100は、基材フィルム101と、基材フィルム101の一面101aに形成(合成)された半導体膜(半導体薄膜)102とを有している。
半導体装置100は、フレキシブルな半導体装置(フレキシブル半導体装置ともいう)であることが好ましい。本明細書において「フレキシブル半導体装置」とは、直径5mmのABS樹脂(アクリロニトリル-ブタジエンースチレン共重合体樹脂)製の棒に半導体装置を10回巻きつけと開放を繰り返した後、目視確認で、半導体装置に割れや欠け等の損傷がないことをいう。
本明細書において、基材フィルム101の線膨張係数(CTE)が5ppm/℃以下である、とは、45℃~75℃での平均値であるCTE(60℃)、285℃~315℃での平均値であるCTE(300℃)、375℃~405℃での平均値であるCTE(390℃)、435℃~465℃での平均値であるCTE(450℃)のすべてが5ppm/℃以下であることを言う。
CTEが前記範囲であると、半導体膜102との線膨張係数の差を小さく保つことができ、熱を加えるプロセスに供しても半導体膜102と基材フィルム101とが剥がれることを容易に回避できる。ここにCTEとは温度に対して可逆的な伸縮を表すファクターである。基材フィルム101のCTEの測定方法は、実施例に記載の方法による。
A.ピロメリット酸残基を有する芳香族テトラカルボン酸類、ベンゾオキサゾール構造を有する芳香族ジアミン類との組み合わせ。
B.ジアミノジフェニルエーテル骨格を有する芳香族ジアミン類とピロメリット酸骨格を有する芳香族テトラカルボン酸類との組み合わせ。

本実施形態おいては、前記ベンゾオキサゾール構造を有する芳香族ジアミンを70モル%以上使用することが好ましい。
半導体装置100を製造するための主要な2工程について、図2を用いて説明する。
基材フィルム101を加熱しながら、基材フィルムの一面101に対し、Ge、SiGe、Si、GeSn、SiC、GaAs、InP、GaN、ZnSe、CdS、ZnO等の粒子102Aを堆積させ、非晶質の半導体膜102Bを形成する(図2の左側)。
熱処理(雰囲気は問わない)を行い、第一工程で形成された非晶質の半導体膜102Bの固相成長を促し、多結晶の半導体膜(多結晶膜)102Cを合成する(図2の右側)。第二工程において、加熱温度は350℃以上800℃以下とすることが好ましく、加熱時間は0.1時間以上300時間以下とすることが好ましい。
このように、本実施形態では、耐熱性に優れ、且つ、高温に晒されたとしても寸法変化が少ない基材フィルム101を用いるため、製造時(第一工程、第二工程等)に高温に晒されたとしても、半導体膜102Cが基材フィルム101から剥離してしまうことを抑制することができる。
また、基材フィルム101として、芳香族ジアミン類と芳香族テトラカルボン酸無水物類とを重縮合して得られたフィルムであり、且つ、長手方向の引張弾性率が7GPa以上であるフィルムを用いるため、製造時(第一工程、第二工程等)に高温に晒されたとしても、半導体膜102Cが基材フィルム101から剥離してしまうことを抑制することができる。
フィルムの厚さは、マイクロメーター(ファインリューフ社製、ミリトロン1254D)を用いて測定した。
乾燥後のフィルムを長手方向(MD方向)に長さ100mm、幅10mmの短冊状に切り出して試験片とし、25℃60%RH環境に24時間シーズニングした後に同一環境下にて、引張試験機(島津製作所製オートグラフ(商品名)機種名AG-5000A)を用い、引張速度50mm/分、チャック間距離40mmの条件で、引張破断強度、引張破断伸度、及び、引張弾性率を測定した。
測定対象のポリイミドフィルムについて、下記条件でMD方向の寸法変化率を測定し、30℃~45℃、45℃~60℃、・・・と15℃の間隔での寸法変化率/温度を測定し、この測定を465℃まで行い、45℃~75℃での測定値の平均値をCTE(60℃)、285℃~315℃での測定値の平均値をCTE(300℃)、375℃~405℃での測定値の平均値をCTE(390℃)、435℃~465℃での測定値の平均値をCTE(450℃)、として算出した。

(ゲルマニウム薄膜の調製1)
分子線堆積法により、上記で得られたポリイミドフィルムC上に、基板温度を125℃に設定した状態で、ゲルマニウム(Ge)粒子を堆積させ、厚さ100nmのGe薄膜を形成(蒸着)した(第一工程)。成膜レートは1nm/minとした。
(ゲルマニウム薄膜の調製2)
前記第一工程において、ゲルマニウム(Ge)粒子の薄膜の厚さを50nmに変更した以外は実施例1と同様に操作した。第二工程を経て得られた厚さ50nmのGe薄膜に対し、走査型電子顕微鏡(SEM)を用いて表面観察を行った。SEM像からは結晶のコントラストのみが観察され、Ge薄膜の剥離やクラックなどは観察されなかった。
(ゲルマニウム薄膜の調製3)
前記第一工程において、ゲルマニウム(Ge)粒子の薄膜の厚さを300nmに変更した以外は実施例1と同様に操作した。第二工程を経て得られた厚さ300nmのGe薄膜に対し、走査型電子顕微鏡(SEM)を用いて表面観察を行った。SEM像からは結晶のコントラストのみが観察され、Ge薄膜の剥離やクラックなどは観察されなかった。
ポリイミドフィルムAを用いて、実施例1と同様の方法にてゲルマニウム薄膜の調製を行った。
実施例1と同様に、基板温度Tdを50℃~200℃の範囲で設定した状態で、ゲルマニウム(Ge)粒子を堆積させ、厚さ100nmのGe薄膜を形成(蒸着)した(第一工程)。成膜レートは実施例1と同じ1nm/minであり、成膜時間も同様の100分間とした。
次いで第二工程として、窒素雰囲気とした電気炉内に導入し、第一工程で形成したGe薄膜に対し、固相成長を促す目的で、375℃で140時間、400℃で60時間、450℃で5時間の熱処理を行った。ところが、いずれの試料においても、基板の収縮によると思われる反りが著しく生じ、400℃、450℃の熱処理を行った試料においてはゲルマニウム薄膜が基板フィルムから剥離していた。そのため、ゲルマニウム薄膜の結晶粒系測定と移動度測定は行えなかった。
ポリイミドフィルムBを用いて、実施例1と同様の方法にてゲルマニウム薄膜の調製を行った。
実施例1と同様に、基板温度Tdを50℃~200℃の範囲で設定した状態で、ゲルマニウム(Ge)粒子を堆積させ、厚さ100nmのGe薄膜を形成(蒸着)した(第一工程)。成膜レートは実施例1と同じ1nm/minであり、成膜時間も同様の100分間とした。
次いで第二工程として、窒素雰囲気とした電気炉内に導入し、第一工程で形成したGe薄膜に対し、固相成長を促す目的で、375℃で140時間、400℃で60時間、450℃で5時間の熱処理を行った。
結果、375℃140時間熱処理の場合には、結晶成長が確認でき、正孔移動度は150cm2/V・sであった。
さらに特性向上を期待して400℃熱処理、450℃熱処理についても観察を行ったが、400℃熱処理品については、フィルムの熱収縮に起因すると思われる皺が生じており、移動度測定は行えなかった。さらに450℃熱処理品においては、フィルム基板の劣化が激しく、非常に脆い状態になっており、電気炉から取り出す際に、ピンセットで摘まみだすことが困難であり、こちらについても評価は断念せざるを得なかった。
