On a silicon substrate, a first insulation layer, a lower conductive layer, a capacitor-insulator layer, and an upper conductive layer are formed in that order. Then, a first resist pattern is formed, the upper conductive layer is etched to form an upper electrode, and the capacitor-insulator layer is successively etched partway under the same etching condition as that of the upper conductive layer. Next, second resist pattern is formed, the remaining part of the capacitor-insulator layer is etched to form a second insulation layer, and the lower conductive layer is successively etched under the same etching condition as that of the capacitor-insulator layer so as to form a lower electrode and a lower wiring. In this manner, an MiM capacitor element constituted by the upper electrode, a part of the second insulation layer, and the lower electrode can be fabricated.

Wiring lines for use at a high frequency having reduced resistance and/or inductance are disclosed that may be readily manufactured in a semiconductor integrated circuit. Wiring lines can include extension lines (2), connected to both ends of an inductor (1), that may each include divided wiring lines (2a and 2b) that are separated by a slit (3). A length, width and thickness of divided wiring lines (2a and 2b) can be essentially equal, resulting in divided wiring lines (2a and 2b) of essentially equal longitudinal resistance. A width of a slit (3) may preferably be greater than a width of each of divided wiring lines (2a and 2b).

A semiconductor device includes a semiconductor substrate; a circuit; a guard ring; a power source line; and a contact. The semiconductor substrate has a first conductive type. The circuit is formed on the semiconductor substrate. The guard ring is formed on the semiconductor substrate such that the guard ring surrounds the circuit. The power source line supplies an electric power both the circuit and the guard ring. The contact is formed on the guard ring and connects the guard ring and the power source line. The guard ring is composed of a semiconductor having a second conductive type opposite to the first conductive type. The contact is placed in an opposite side of a noise source over the circuit.

Disclosed are an inductor for a semiconductor integrated circuit, which provides a wider cross-sectional area, significantly reduces the resistance to improve the Q value and has a highly uniform film thickness, and a method of fabricating the inductor. A spiral inductor is formed on a topmost interconnection layer of a multilayer interconnection layer formed by a damascene method. This inductor is formed by patterning a barrier metal layer on an insulation film, on which a topmost interconnection is formed, in such a way that the barrier metal layer contacts the topmost interconnection, then forming a protective insulation film on an entire surface of the barrier metal layer, forming an opening in that portion of the protective insulation film which lies over the barrier metal layer, forming a thick Cu film with the barrier metal layer serving as a plating electrode, and performing wet etching of the Cu film. This process can allow the inductor to be so formed as to be thick and have a wide line width.
