摘要
PROBLEM TO BE SOLVED: To provide a first low resistance condition and a second higher resistance condition, and switch a condition to the second condition from the first condition when an electric current passes by including a polysilicon area coated with a silicide area of an upper surface between two contacts. ;SOLUTION: An upper surface 3 of a polysilicon area 2 formed on a separating layer 1 is silicified. First low resistivity can be substantially obtained by high electric conductivity of a silicide area (a first condition). When a high electric current flows between metallization contacts 5 and 6, a resistance between the contacts 5 and 6 is connected to a doping level of the polysilicon area 2, and reaches a very high value (a second condition). Programming is performed so as to automatically become the first or the second condition when power is turned on according to a condition of a pseudo-fuse.;COPYRIGHT: (C)1998,JPO
