Description
[0002] 光学デバイスは、基板上に形成される光学デバイスの構造の空間的に変化する構造パラメータ(例えば、形状、サイズ、配向)によって、光の伝搬を操作するために使用されてもよい。光学デバイスは、必要に応じて光波面を成形する空間的に変化する光学応答を提供する。光学デバイスのこれらの構造は、局所化された位相不連続性(すなわち、光の波長よりも小さい距離にわたる位相の急激な変化)を誘起することによって、光の伝搬を変化させる。これらの構造は、基板上の異なるタイプの材料、形状、または配置によって構成されてもよく、異なる物理的原理に基づいて動作してもよい。
アクチュエータ706は、FOUP801aの中へアーム708を延ばし、スロット804aからキャリアアセンブリ600を受け取る。アクチュエータアーム708は、キャリアアセンブリ600をアライナ711上に配置する。アクチュエータ706は、アーム708を後退させる。アライナ711は、アセンブリ600を配向する。アーム708は、位置合わせされたアセンブリ600を受け取り、リフトアセンブリ600を真空チャック710に向かって所定距離903だけ持ち上げる。真空チャック710は、基板201を固定するため内側領域901に係合し、マスク301を固定するため外側領域902に係合する。基板201およびマスク301を後方に残して、アーム708はキャリア601を下降させる。アクチュエータ706は、アーム708およびキャリア601を後退させる。アクチュエータ707は、アーム709を真空チャック710の下方に延ばす。アーム708は、真空チャック710上で基板201を受け取るため距離903だけ上昇する。真空チャック710は、領域901をオフにして基板201を解放する。アーム709は、基板201を下降させる。アクチュエータ707は、アーム709を延ばして、基板201をフリッパデバイス803の中に配置する。アクチュエータ707は、アーム709を後退させる。フリッパデバイス803は、基板201を基板201の裏面に対して180度反転する。アーム709は、フリッパデバイス803の中に延び、基板201を受け取る。アクチュエータアーム709は、基板201をアライナ711に移送する。アクチュエータ707はアーム709を後退させ、アライナ711は基板201を位置合わせする。アーム709は、位置合わせされた基板201を受け取り、基板201を真空チャック710まで距離903だけ持ち上げる。真空チャック710は、内側領域901をチャック基板201に係合させる。アクチュエータ707は、アーム709を下降および後退させる。アクチュエータ706は、アーム708およびキャリア601を真空チャック710の下方に延ばす。アーム708は、キャリア601を真空チャック710まで持ち上げる。真空チャック710は、内側領域901および外側領域902の係合を解除し、基板201およびマスク301をキャリア601上に解放する。アクチュエータアーム708は、フルキャリアアセンブリ600を下降させる。アクチュエータアーム708は、FOUP801aの中へ延び、フルキャリアアセンブリ600をスロット804aに戻す。FOUP801aのすべてのアセンブリが完了するまで、上記で開示した構築処理が繰り返される。基板201が反転された状態で、FOUP801aのすべてのアセンブリ600が完了すると、FOUP801bに対して処理が繰り返される。上記で開示した処理は、FOUP801aおよび801b内で基板201が反転された状態で、完全に組み立てられたキャリアアセンブリ600をもたらす。次に、キャリアアセンブリ600は、裏面で基板201を処理する準備が整う。上記で開示した処理は、マスク301なしで完了することもでき、その結果、キャリア601および反転された基板201を有するアセンブリが得られる。
