Claim Text:
1. A method for manufacturing a semiconductor device comprising: forming an insulating film above a stacked body including a first layer as an uppermost layer; forming a mark having a first opening above the stacked body via the insulating film; etching the insulating film exposed from the first opening and the stacked body located under the first opening so as to form a second opening in the insulating film and the stacked body, the mark being transferred to the second opening; and forming a second layer including a same material as the first layer in the second opening, wherein the process of the forming the second layer includes: forming the second layer in the second opening and forming the second layer on the insulating film; and removing the second layer formed on the insulating film and the insulating film so as to expose the first layer from the insulating film and making flush an upper surface of the second layer formed in the second opening and an upper surface of the first layer.
