Abstract
A semiconductor device containing a dielectric capacitor having an excellent step coverage for a device structure of high aspect ratio corresponding to high integration degree, as well as a manufacturing method therefor are provided. A dielectric capacitor of high integration degree is manufactured by forming a bottom electrodeand a top-electrodecomprising a homogeneous thin Ru film with 100% step coverage while putting a dielectrictherebetween on substrateshaving a three-dimensional structure with an aspect ratio of 3 or more by a MOCVD process using a cyclopentadienyl complex within a temperature range from 180° C. or higher to 250° C. or lower.
