A Review On Variable MEMS Mirrors For Photo-Lithographic Masks

Abstract

This paper presents a review on using MEMS based mirror arrays to achieve maskless lithography in order to eliminate mask costs in the micro fabrication processes. With the advanced technology nodes, it becomes more and more costly to produce the lithography masks. Especially with the extreme ultraviolet lithography technique, the necessity to use maskless lithography becomes more obvious. Several universities and companies fabricated tilting mirror style or piston style mirror arrays to propose a solution to maskless lithography processes.

Foto-Litografik Maskeler İçin Değişen MEMS Aynaları Üzerine Bir Derleme

Abstract

Bu makale MEMS tabanlı mikro-ayna dizilerinin mikro-üretim adımlarında maske maliyetini azaltmak için maskesiz litografi elde etmek amaçlı kullanılması hakkında bir derleme sunmaktadır. Gelişmiş teknoloji nodlarıtla birlikte litografi maskelerini üretmek daha da pahalı olmaktadır. Özellikle EUV (ekstrim ultraviolet litografi) tekniğinde, maskesiz litografi kullanmak ihtiyacı daha da aşikar olmuştur. Maskesiz litografi adımlarına bir çözüm olması amacıyla, çeşitli üniversite ve şirketler dönen veya piston şeklinde mikro-ayna dizileri üretmiştir.
