Abstract:
A dielectric capacitor having a structure in which a first electrode layer, a dielectric film and a second electrode layer are stacked in this order, wherein:the dielectric capacitor in which an interlevel insulator with a trench is provided and, a stacking structure formed with the first electrode layer, the dielectric film and the second electrode layer is burred in the trench,the first electrode layer and the dielectric film each take a shape according to the configuration of the bottom and side of the trench of the interlevel insulator and both edges of the first electrode layer and the interlevel insulator form a same surface along with each surface of the second electrode layer and the interlevel insulator; anda cross section of the trench takes a shape of rectangle or square, and the first electrode layer and the dielectric film each take a shape of concave.
