    • The invention relates to a method for production of a semiconductor structure, comprising the steps: preparation of a semiconductor substrate (1), generation of a lower first, a middle second and an upper third masking layer (5, 7, 9) on a surface of the semiconductor substrate (1), formation of at least one first window (11, 11a-h) in the upper third masking layer (9), structuring the middle second masking layer (7) using the first window (11, 11a-h) in the upper third masking layer (9) for the transfer of the first window (11, 11a-h), structuring the lower first masking layer (5) using the first window (11, 11a-h) in the middle second masking layer (7) for the transfer of the first window (11, 11a-h), enlarging the first window (11, 11a-h) in the upper third masking layer (9) to form a second window (13, 13a-b) in a maskless process step, restructuring the middle second masking layer (7) using the second window (13, 13a-b) in the upper third masking layer (9) for the transfer of the second window (13, 13a-b), structuring the semiconductor substrate (1), using the structured lower third masking layer (5), restructuring the lower first masking layer (5) using the second window (13, 13a-b) in the middle second masking layer (7) and restructuring the semiconductor substrate (1) using the restructured lower third masking layer (5).
    • 本发明提供了一种半导体结构制造方法,包括以下步骤:提供半导体衬底(1); 在所述半导体衬底(1)的表面上提供下第一掩膜层,中间第二掩膜层和上第三掩膜层(5,7,9); 在所述上部第三掩模层(9)中形成至少第一窗口(11,11a-h); 使用上部第三掩模层(9)中的第一窗口(11,11a-h)图案化中间第二掩模层(7)以传递第一窗口(11,11a-h); 使用中间第二掩模层(7)中的第一窗口(11,11a-h)构造下部第一掩模层(5)以传送第一窗口(11,11a-h); 扩大上部第三掩模层(9)中的第一窗口(11,11a-h)以在无掩模工艺步骤中形成第二窗口(13,13a-b); 使用上部第三掩模层(9)中的第二窗口(13,13a-b)重构中央第二掩模层(7)以传送第二窗口(13,13a-b); 使用图案化的下第三掩模层(5)图案化半导体衬底(1); 使用中间第二掩模层(7)中的第二窗口(13,13a-b)重构下部第一掩模层(5); 以及使用重构的下第三掩模层(5)重构半导体衬底(1)。
