Moreover, a polysilicon film 6 is deposited thereon. Then, a slit is made in the polysilicon film 6 in a memory region, and the polysilicon film 6 is removed from a logic region. Furthermore, when a resist pattern is formed for the implantation of ions, the gate insulating film 4 is contaminated by the attachment of resist. Then, ions are implanted so as to control a logic transistor in threshold value. At this point, an impurity level is formed in the gate insulating film 4 on the logic region through the passage of ions. Then, the contaminated gate insulating film 4 on the logic gate is separated off. Thereafter, a new gate insulating film 7b of a logic transistor is formed at the same time together with the insulating film 7a.
