    • A photo mask for fabricating a semiconductor device having a dual damascene structure which has a via coupled with a lower wiring layer and has an upper wiring layer coupled with the via. The via and the upper wiring layer are fabricated by filling a via hole and a wiring groove formed in an interlayer insulating film that is formed on the lower wiring layer with a wiring material. The photo mask has a via alignment mark which is used for aligning the via hole with respect to the lower wiring layer and/or a via alignment mark which is used for aligning the wiring groove with respect to the via hole. The width of the via alignment mark is equal to or larger than the width which is optically detectable and an aspect ratio of the via alignment mark is equal to or larger than one fourth of the aspect ratio of the via hole. Preferably, the width of the via alignment mark is equal to or larger than the width of the via hole.
    • 一种用于制造具有双镶嵌结构的半导体器件的光掩模,其具有与下布线层耦合的通孔,并且具有与通孔耦合的上布线层。 通孔和上部布线层通过在布线层下方填充形成在层间绝缘膜上的通孔和布线槽来制造。 光掩模具有用于使通孔相对于下布线层对准的通孔对准标记和/或用于使布线槽相对于通孔对准的通孔对准标记。 通孔对准标记的宽度等于或大于可光学检测的宽度,并且通孔对准标记的纵横比等于或大于通孔的纵横比的四分之一。 优选地,通孔对准标记的宽度等于或大于通孔的宽度。

    • A method of manufacturing a semiconductor device having a damascene structure contains a process of forming a first interlayer insulating film (6) and a second interlayer insulating film (4) formed of a low dielectric-constant film on a substrate, forming via holes (9) by using a first resist pattern (1a) formed on the second interlayer insulating film, conducting an organic peeling treatment using organic peeling liquid containing amine components and then forming a second resist pattern (1b) on the second interlayer insulating film. After the wet treatment, before a second antireflection coating (2b) is coated so as to be located below the second resist pattern is coated, at least one of an annealing treatment, a plasma treatment, a UV treatment and an organic solvent treatment is carried out to remove amine components which inhibit the catalysis reaction of acid occurring in the resist at the light exposure, thereby preventing degradation of the resolution of the second resist pattern (1b).
    • 一种制造具有镶嵌结构的半导体器件的方法包括在衬底上形成第一层间绝缘膜(6)和由低介电常数膜形成的第二层间绝缘膜(4)的工艺,形成通孔(9 )通过使用形成在第二层间绝缘膜上的第一抗蚀剂图案(1a),使用含有胺成分的有机剥离液进行有机剥离处理,然后在第二层间绝缘膜上形成第二抗蚀剂图案(1b)。 在湿处理之后,涂覆第二抗反射涂层(2b)以便位于第二抗蚀图案下方的涂层,退火处理,等离子体处理,UV处理和有机溶剂处理中的至少一个是 进行以除去抑制在曝光时在抗蚀剂中发生的酸的催化反应的胺成分,从而防止第二抗蚀剂图案(1b)的分辨率的劣化。
