There are provided a semiconductor device manufacturing method including: forming a film to be processed above a substrate; forming a resist layer above the film to be processed; transferring a transfer pattern to the resist layer using a reticle including the transfer pattern having a space having a width that becomes narrower than a smallest processing space width when transferred to the resist layer; performing trimming processing on the resist layer including the transfer pattern as transferred; and patterning the film to be processed using the resist layer, on which the trimming processing has been performed, as a mask.
