CROSS REFERENCE TO RELATED APPLICATIONS This application is a Continuation of International Application No. PCT/JP03/09725, with an international filing date of Jul. 31, 2003, which designated the United States of America.
BACKGROUND ART As a resistance element incorporated in a semiconductor device, presently a resistance element of polysilicon film is predominantly used. This is because of merits of the good compatibility of the step of forming the resistance element of polysilicon film with the rest process for fabricating the semiconductor device, and the low bias dependency of the resistance element of polysilicon.
BRIEF DESCRIPTION OF DRAWINGS FIGS. 1A and 1B are diagrammatic views of the semiconductor device according to the present invention, which illustrate a structure thereof.
