Description
実施形態に係る洗浄剤組成物は、基板上に存在するシリコーン化合物を含有する仮接着材(シリコーン系接着剤)を除去するために用いられる洗浄剤組成物(基板用仮接着材の洗浄液)である。上記洗浄剤組成物は、(A)有機溶媒:75~99質量部と、(B)水:0~5質量部と、(C)アンモニウム塩:1~20質量部とを含有する。但し、上記(A)成分、(B)成分及び(C)成分の量の合計は100質量部である。上記有機溶媒は、水酸基を有する有機溶媒を含有せず、上記有機溶媒100質量部中に、ヘテロ原子を有する有機溶媒を50質量部以上含有し、上記アンモニウム塩が、水酸化物イオン、フッ化物イオン及び塩化物イオンのうち少なくとも1種を含有する。
実施形態に係る基板の洗浄方法は、支持体と、該支持体上に形成された仮接着層と、該仮接着層に回路面を有する表面が対向するように積層された基板とを備える基板積層体から、上記支持体を剥離し、上記基板上に残存している上記仮接着層を、上述した洗浄剤組成物により洗浄して除去する工程を含む。上述した洗浄剤組成物を用いると、上記基板上に残存している上記仮接着層(すなわち仮接着層を構成していたシリコーン系接着剤のうち基板上に残存するシリコーン系接着剤)を充分に除去できる。
工程(a)は、基板積層体を準備する工程である。図1は、基板積層体を説明するための図である。図1は、基板積層体10の断面図を示しており、基板積層体10は、支持体1と、該支持体1上に形成された仮接着層2と、該仮接着層2に回路面を有する表面が対向するように積層された基板3とを備える。
未硬化組成物は、たとえば、(A-1)1分子中に2個以上のアルケニル基を有するオルガノポリシロキサン、(A-2)1分子中に2個以上のケイ素原子に結合した水素原子(Si-H基)を含有するオルガノハイドロジェンポリシロキサン、及び(A-3)白金系触媒を含む。ここで、成分(A-1)中のアルケニル基に対する成分(A-2)中のSi-H基のモル比は0.3以上10以下である。また、未硬化組成物は、(A-4)有機溶剤又は(A-5)反応制御剤を含んでいてもよい。
R7 (3-a)XaSiO-(R7XSiO)m-(R7 2SiO)n-SiR7 (3-a)Xa (1)
R7 2(HO)SiO-(R7XSiO)p+2-(R7 2SiO)q-SiR7 2(OH) (2)
(SiO4/2)b(R7 3SiO1/2)c(R7 (3-e)XeSiO1/2)d (3)
硬化層(A)は、上述のように、未硬化組成物層を熱硬化させて得られ、未硬化組成物の硬化物を含む。
工程(b)は、基板積層体における基板の裏面を研削又は研磨する工程である。工程(b)では、支持体と接合した基板の裏面(回路非形成面)を研削又は研磨する。これにより、基板の厚みが薄くなる。薄型化された基板の厚さは、典型的には5μm以上300μm以下、より典型的には10μm以上100μm以下である。研削加工の方式には特に制限はなく、公知の方式で行うことができる。研削は、基板及び砥石(ダイヤモンドなど)に水をかけて冷却しながら行うことが好ましい。基板の裏面を研削加工する装置としては、たとえば株式会社ディスコ製DAG-810(商品名)などが挙げられる。また、基板の裏面をCMP研磨してもよい。
工程(c)は、基板の裏面に加工を施す工程である。工程(c)では、工程(b)で裏面研削又は裏面研磨によって薄型化された基板の裏面(回路非形成面)に加工を施す。この工程にはウエハレベルで用いられる様々なプロセスが含まれる。この工程としては、電極形成、金属配線形成、保護膜形成などが挙げられる。より具体的には、電極等の形成のための金属スパッタリング、金属スパッタリング層をエッチングするウェットエッチング、金属配線形成のマスクとするためのレジストの塗布、露光及び現像によるパターンの形成、レジストの剥離、ドライエッチング、金属めっきの形成、TSV形成のためのシリコンエッチング、シリコン表面の酸化膜形成など、従来公知のプロセスが挙げられる。また、ダイシングなどにより薄型化したウエハをチップサイズに切断することも含まれる。
工程(d)は、基板積層体から支持体を剥離する工程である。工程(d)では、工程(c)で加工を施した基板積層体から支持体を剥離する。剥離工程は、一般に室温から60℃程度の比較的低温の条件で実施される。基板積層体の基板又は支持体の一方を水平に固定しておき、他方を水平方向から一定の角度を付けて持ち上げて行うことができる。また、基板の研削面に保護フィルムを貼り、保護フィルムとともに基板をピール方式で剥離してもよい。
工程(e)は、上記洗浄剤組成物により、基板の表面を洗浄する工程である。工程(e)では、上記洗浄剤組成物により、基板の表面(回路形成面)に残存する硬化層(A)(未硬化組成物の硬化物)を洗浄し除去する。これにより、工程(d)にて支持体及び硬化層(A)を剥離した後にも、基板の表面に一部残存する硬化層(A)も充分に除去できる。このような基板(薄型ウエハ)は、引き続き3次元の半導体実装のプロセスに好適に用いられる。
以下、実施例を示し、本発明を具体的に説明するが、本発明は下記の実施例に制限されるものではない。
ジメチルスルホキシド90質量部中にフッ化テトラブチルアンモニウム3水和物を10質量部加え、室温で撹拌し、表1-1に記載の組成(質量部)を有する洗浄剤組成物Aを得た。すなわち、得られた洗浄剤組成物Aは、ジメチルスルホキシド90質量部、フッ化テトラブチルアンモニウム3水和物由来のフッ化テトラブチルアンモニウム8質量部、フッ化テトラブチルアンモニウム3水和物由来の水2質量部を含む。
表1-1、1-2に記載の各組成(質量部)を有するように、有機溶媒中にアンモニウム塩の水和物を加え、室温で撹拌し洗浄剤組成物B、C、D、E、F、G、H、I、J及びKを得た。なお、得られた洗浄剤組成物Iは、ジメチルスルホキシド90質量部、フッ化テトラメチルアンモニウム4水和物由来のフッ化テトラメチルアンモニウム6質量部、フッ化テトラメチルアンモニウム4水和物由来の水4質量部を含む。

TMAF:フッ化テトラメチルアンモニウム
TMAH:水酸化テトラメチルアンモニウム
DMSO:ジメチルスルホキシド
PGMEA:プロピレングリコールモノメチルエーテルアセテート
まず、下記のようにして樹脂溶液を調製した。
2.0モル%のビニル基を両末端及び側鎖に有し、分子末端がSiMe2Vi基で封鎖されており、GPCによる数平均分子量(Mn)が5万のポリジメチルシロキサン100質量部、及びイソドデカン400質量部からなる溶液に下記式(M-1)で示されるオルガノハイドロジェンポリシロキサンを3.5部(アルケニル基に対して2モル)、エチニルシクロヘキサノール0.7部を添加し混合した。さらに白金触媒CAT-PL-5(信越化学工業株式会社製)を0.5部添加し、0.2μmのメンブレンフィルターで濾過して、樹脂溶液を得た。
〔工程(a)〕
基板積層体を準備した。具体的には、支持体としての200mmガラスウエハ(厚さ:700μm)上に、樹脂溶液をスピンコート後、ホットプレートにて、100℃で5分間加熱して、仮接着材層(厚さ:35μm)を積層した。次いで、基板として直径200mmシリコンウエハ(厚さ:725μm)を、支持体と接合した。接合は、ウエハ接合装置(EVG社製、EVG520IS(商品名))により行った。また、接合温度は50℃、接合時のチャンバー内圧力は10-3mbar以下、荷重は10kNで実施した。接合後、オーブンを用いて200℃で2時間、接合済み基板を加熱し、仮接着材層を硬化させ、室温まで冷却した。このようにして、基板積層体を得た。
次いで、基板積層体における基板の裏面を研削した。具体的には、グラインダー(株式会社ディスコ製、DAG810(商品名))でダイヤモンド砥石を用いてシリコンウエハの裏面研削を行った。最終基板厚50μmまでグラインドした。
次いで、基板の裏面に加工を施す工程として、模擬的に加熱工程を行った。具体的には、裏面研削を行った基板積層体を、260℃のホットプレート上で10分加熱した。
次いで、基板積層体から支持体を剥離した。具体的には、シリコンウエハの裏面(回路非形成面)にダイシングフレームを用いてダイシングテープを貼り、このダイシングテープ面を真空吸着によって、吸着板にセットした。その後、室温にて、ガラスウエハの1点をピンセットにて持ち上げることで、ガラスウエハと仮接着材層を剥離した。
次いで、洗浄剤組成物Aにより、基板の表面を洗浄した。具体的には、洗浄剤組成物Aにシリコンウエハを5分間浸漬した後、乾燥した。
洗浄剤組成物Aの代わりに、洗浄剤組成物B~洗浄剤組成物K及び、比較洗浄剤組成物L~洗浄剤組成物Nを用いた以外は実施例12と同様にして基板の洗浄を行った。
実施例12~22及び比較例5~7で洗浄した基板の評価を下記方法にて行った。
測定装置:KRATOS製 AXIS-Ultra DLD
一方、本発明の要件を満たさない比較例5~7では良好な洗浄性を得ることはできなかった。さらに比較例4においては、良好な洗浄剤組成物を得ることもできなかった。
用効果を奏するものは、いかなるものであっても本発明の技術的範囲に包含される。
2…仮接着層(硬化層(A))
3…基板
10…基板積層体
