Projection exposure equipment
Abstract
Abstract Translated from Japanese (57)【要約】 【課題】 感光剤を塗布した基板に高エネルギの露光光 を照射した際にも、投影光学系等に微粒子が付着して汚 染されることを防止する。 【解決手段】 感光剤Kを塗布した基板Wに、露光光B によりマスクのパターンを投影露光する投影露光装置に おいて、露光光Bを透過させるとともに、基板Wの感光 剤塗布面18を少なくとも収納するチャンバ15を備え る。 [PROBLEMS] To prevent contamination of a projection optical system or the like due to fine particles even when a substrate coated with a photosensitive agent is irradiated with high-energy exposure light. SOLUTION: Exposure light B is applied to a substrate W coated with a photosensitive agent K. In the projection exposure apparatus for projecting and exposing a pattern of a mask, a chamber 15 for transmitting exposure light B and accommodating at least a photosensitive agent application surface 18 of the substrate W is provided.
