发明名称 METHOD FOR PRODUCING SEMICONDUCTOR DEVICE AND SEMICONDUCTOR DEVICE
摘要 A method for producing semiconductor device includes: performing first, second and third exposures of a photoresist film formed on a semiconductor wafer via a mask; wherein: first, second and third shot regions respectively defined by the first, second and third exposures are aligned in a first direction; the mask has a shot region including a peripheral scribe region having a first and second side crossing the first direction; the photoresist film is of positive type, a first pattern is formed as a light shielding pattern disposed on the first side, and a second pattern is formed as a light transmitting region disposed on the second side; the first and second exposures are performed in such a manner that the first and second patterns do not overlap each other; and the second and third exposures are performed in such a manner that the first and second patterns overlap each other.
