Definitions

- the present invention relates to a pellicle for lithography using an excimer laser used in exposure that requires high resolution.
- a semiconductor manufacturing apparatus such as a stepper (reduced projection exposure apparatus) is used to form a photoresist pattern corresponding to an integrated circuit on a wafer.
- the pellicle is formed by stretching a transparent thin film on one end surface of a pellicle frame, and prevents foreign matter from directly adhering to the mask in order to form a circuit pattern. Therefore, even if foreign matter adheres to the pellicle in the photolithography process, the foreign matter does not form an image on the wafer coated with the photoresist, thereby preventing a short circuit or disconnection of the semiconductor integrated circuit due to the foreign matter image. And the yield in the photolithography process can be improved.
- the pellicle is fixed on the mask with a pellicle adhesive and can be attached to and detached from the mask.
- a pellicle adhesive acrylics, rubbers, polybutenes, polyurethanes, silicones, and the like are known (see Patent Document 1 below).

- the degree of weight swelling can be controlled by adjusting the content of the crosslinking agent.
- Swelling is a state in which solvent molecules (for example, toluene) enter between the molecules of the polymer (polymer), and the force for expanding the molecules is balanced with the elasticity of the crosslinked network. Since the degree of swelling is affected by the affinity between the solvent and the polymer and the degree of crosslinking of the polymer, the weight swelling degree can be controlled by adjusting them.

- the weight swelling degree also depends on the degree of crosslinking of the polymer. If the degree of cross-linking is too low, solvent molecules will not be incorporated into the polymer cross-linking network and the weight swell will be low. On the other hand, when the degree of crosslinking is too high, solvent molecules cannot enter the polymer crosslinking network, and the weight swelling degree becomes small. Therefore, the degree of weight swelling can be controlled by appropriately adjusting the degree of crosslinking of the polymer.

If the content of the cross-linking agent is 0.20 parts by mass or less, the cross-linking density does not increase too much, so the pressure-sensitive adhesive absorbs the stress applied to the photomask, and the effect of the pressure-sensitive adhesive on the flatness of the photomask is mitigated. It is thought that it is done.
- the content of the cross-linking agent is 0.05 parts by mass or more, the cross-linking density does not become too small, so that the handleability during the manufacturing process is maintained, and the adhesive residue is left when peeling the pellicle from the photomask. Is considered to be difficult to occur.
- the degree of weight swelling can be increased up to about 15 times by appropriately adjusting the degree of crosslinking of the polymer. Can be controlled.

<ペリクル>
図1は、第一の本発明の一実施形態(第一実施形態)に係るペリクルを示す斜視図であり、図2は、図1におけるII-II線断面図である。図1及び図2に示すように、ペリクル1は、ペリクル枠体2と、ペリクル枠体2の一端面2eに張設されたペリクル膜3と、ペリクル枠体2の他端面2fに付着した粘着剤10(粘着剤層)と、粘着剤10の表面を被覆し、この粘着剤10を保護する保護フィルムFとを備える。
ペリクル用粘着剤10は、(メタ)アクリル酸アルキルエステル共重合体と、シラン化合物とを含む。なお、粘着剤10は、下記第二実施形態と同様に、ラジカル捕捉剤及び/又は紫外線吸収剤をさらに含有してもよい。該(メタ)アクリル酸アルキルエステル共重合体は、炭素数4~14のアルキル基を有する(メタ)アクリル酸アルキルエステル(以下「A成分」という。)と、イソシアネート基又はエポキシ基の少なくともいずれかとの反応性を有する官能基を有するモノマー(以下「B成分」という。)との少なくとも2つのモノマー成分を共重合させることによって得られる共重合体である。このような粘着剤は、マスクとの接着力が十分で、且つ、剥離後の糊残りが少ないという点で好ましい。
A成分のモノマーを、炭素数4~14のアルキル基が直鎖状のもの(以下「A1成分」という。)と炭素数4~14のアルキル基が分岐状のもの(以下「A2成分」という。)に分けた場合、上記(メタ)アクリル酸アルキルエステル共重合体は、A2成分の含有割合が9~59質量部である単量体混合物の共重合体であることが好ましい。これにより、粘着剤の粘着力が向上する。
B成分は、上記A成分のモノマーと共重合可能なモノマーであって、イソシアネート基又はエポキシ基の少なくともいずれかとの反応性を有する。B成分の具体例としては、(メタ)アクリル酸、イタコン酸、マレイン酸、クロトン酸等のカルボキシル基含有モノマーや、(メタ)アクリル酸2-ヒドロキシエチル、(メタ)アクリル酸3-ヒドロキシプロピル、(メタ)アクリル酸2-ヒドロキシプロピル、(メタ)アクリル酸4-ヒドロキシブチル等のヒドロキシル基含有モノマーが挙げられる。これらは単独でも2種以上併せて用いてもよい。なかでも、共重合性、汎用性等の点から、(メタ)アクリル酸2-ヒドロキシエチル、(メタ)アクリル酸4-ヒドロキシブチル等の炭素数2~4のヒドロキシアルキル基を有するヒドロキシル基含有(メタ)アクリレート、(メタ)アクリル酸等のカルボキシル基含有モノマーがB成分として好適である。特に糊残りを低減する点から、B成分としては、(メタ)アクリル酸が好ましい。(メタ)アクリル酸の含有割合は、(メタ)アクリル酸アルキルエステル共重合体を構成する全モノマーの合計100質量部に対して好ましくは0.1~5質量部であり、より好ましくは0.5~4質量部であり、特に好ましくは0.8~3質量部である。
上記(メタ)アクリル酸アルキルエステル共重合体を構成する全モノマーの合計100質量部に対して、上記のA1成分のアクリレート系モノマーの割合は、40~90質量部、好ましくは45~80質量部である。同様に、A2成分の割合は好ましくは9~59質量部であり、より好ましくは15~50質量部である。同様に、B成分の割合は好ましくは1~20質量部であり、より好ましくは2~10質量部である。つまり、上記(メタ)アクリル酸アルキルエステル共重合体は、A1成分の含有割合が40~90質量部であり、A2成分の含有割合が9~59質量部であり、B成分の含有割合が1~20質量部である単量体混合物の共重合体であることがより好ましい。これにより、ペリクルの剥離後の糊残りを低減し易くなる。
溶液重合の一具体例では、窒素等の不活性ガス気流下でモノマーの混合溶液に重合開始剤を加え、50~70℃で、8~30時間重合反応を行う。重合開始剤の添加量は、(メタ)アクリル酸アルキルエステル共重合体を構成する全モノマーの合計100質量部に対して0.01~2.0質量部である。ラジカル重合に用いられる重合開始剤は下記のものの中から適宜選択すればよい。連鎖移動剤、乳化剤等は、特に限定されず、公知のものを宜選択して使用すればよい。
粘着剤に添加される架橋剤(硬化剤)は、(メタ)アクリル酸アルキルエステル共重合体と、反応性を有するものである限り、特に限定されない。具体的な架橋剤としては、多官能性エポキシ化合物、金属塩、金属アルコキシド、アルデヒド系化合物、非アミノ樹脂系アミノ化合物、尿素系化合物、イソシアネート系化合物、金属キレート系化合物、メラミン系化合物、アジリジン系化合物等、通常の粘着剤に使用される架橋剤を挙げることができる。中でも、(メタ)アクリル酸アルキルエステル共重合体が有する官能基成分との反応性に優れる点において、イソシアネート系化合物又は多官能性エポキシ化合物がより好ましく、多官能性エポキシ化合物が架橋剤として好適である。
ペリクル用粘着剤は、シラン化合物を含有する。シラン化合物は、-(Si-O)-を主骨格に有することが好ましい。さらに、糊残りを低減し易い点において、シラン化合物がポリアルキレンオキシド骨格またはエポキシ基を有することがより好ましい。耐過重性を向上させ易い点において、シラン化合物がポリアルキレンオキシド骨格及びエポキシ基を有することが特に好ましい。中でも、シラン化合物がその側鎖(主鎖末端でない部分)に、ポリアルキレンオキシド骨格及びエポキシ基を有することが最も好ましい。
また、粘着剤は、必要に応じて、充填剤、顔料、希釈剤、老化防止剤等の添加剤を含んでいてもよい。これらの添加剤は、1種類又は2種以上を使用することが可能である。ただし、所望する物性が得られるように、添加量は適時設定することが好ましい。
以下では、第二の本発明の一実施形態(第二実施形態)と第一実施形態との相違点についてのみ説明する。第二実施系形態は、下記の事項を除いて第一実施形態と同じであり、第一実施形態と同様の効果を奏するものである。
上記実施形態に係るペリクルは、例えば以下の方法で好適に製造することができる。
本実施形態に係るペリクル付フォトマスクには、上記第一実施形態又は第二実施形態のペリクルが装着されている。
本実施形態に係る半導体素子の製造方法は、上記のペリクル付フォトマスクによって基板を露光する工程を備える。半導体素子の製造工程の一つであるフォトリソグラフィー工程において、集積回路に対応したフォトレジストパターンをウエハー(基板)上に形成するために、ステッパーに上記のペリクル付フォトマスクを設置して露光する。これにより、仮にフォトリソグラフィー工程において異物がペリクル上に付着したとしても、フォトレジストが塗布されたウエハー上にこれらの異物は結像しないため、異物の像による半導体集積回路の短絡や断線等を防ぐことができる。よって、ペリクル付フォトマスクの使用により、フォトリソグラフィー工程における歩留まりを向上させることができる。
