Abstract
Description
[0001]本開示の実施形態は、一般に、マイクロエレクトロニクス処理に関連し、より詳細には、ナノインプリントリソグラフィ(NIL)に有用なインプリント組成物及び材料並びに関連するプロセスに関連する。
関連技術の説明
[0002]ナノ粒子インプリントのナノ及びマイクロパターニングは、ナノ材料ベースの電子機器、エネルギーデバイス、センサ、及びナノメートルスケールの解像度を有する他のタイプのデバイスを開発する機会を提供する。現在入手可能なインプリント材料には、有機(高屈折率ポリマー)又は無機-有機ハイブリッド材料(ゾル-ゲル)のいずれかが含まれている。インプリント材料の大部分は、屈折率が低く(<1.7)、可視領域の光学的透明性、光学的解像度、加工性、インプリントされたフィーチャの高い収縮、及び費用対効果に関連する複数の問題がある。
[0032]1つ又は複数の実施形態では、NILフィルムなどのインプリントされた表面を調製するための方法が提供される。インプリントされた表面は、ここで説明及び議論されているナノインプリントフィルムの1つ又は複数の露出面である。この方法は、インプリント組成物を1つ又は複数の基板上に配置、コーティング、又は他の方法で配置すること、インプリント組成物を、パターンを有するスタンプと接触させること、インプリント組成物をインプリント材料(例えば、ナノインプリントフィルム)に変換すること、及びインプリント材料からスタンプを除去することを含む。いくつかの例では、基板(例えば、ウエハ)は、ガラス、石英、ガラス基板又はガラスウエハなどの酸化ケイ素であり得るか、又はそれらを含み得る。他の例では、基板は、シリコン、シリコンゲルマニウム、プラスチック、及び/又は他の材料であるか、あるいはそれらを含むことができる。インプリント組成物は、約1.7~約2.0の屈折率を有することができる。スタンプ上の、そしてインプリントされた表面に転写されるパターンは、1次元パターン、2次元パターン、又は3次元パターンのいずれかである。
