摘要:
A semiconductor device is produced by fabricating a capacitor element including a lower electrode, a capacitor insulating film, and an upper electrode, and a thin-film resistor element, in the same step. As the lower electrode of the capacitor element is lined with a lower layer wiring layer (Cu wiring), the lower electrode has extremely low resistance substantially. As such, even if the film thickness of the lower electrode becomes thinner, parasitic resistance does not increased. The resistor element is formed to have the same film thickness as that of the lower electrode of the capacitor element. Since the film thickness of the lower electrode is thin, it works as a resistor having high resistance. In the top layer of the passive element, a passive element cap insulating film is provided, which works as an etching stop layer when etching a contact of the upper electrode of the capacitor element.

摘要:
In a capacitor element in which a highly dielectric metal oxide film formed between wiring layers is used as a capacitor insulation film, the diffusion and thermal oxidation of a lower-layer wiring material are reduced, and the surface on which a thin capacitor insulation film that constitutes a capacitor element is formed is kept flat. A lower electrode (111b) having the ability to prevent diffusion of the wiring material is embedded and formed so as to be in direct contact with a lower-layer wiring (105) in a prescribed area of a wiring cap film (103), and the surface on which the capacitor insulation film is formed is flat. The wiring cap film functions to prevent diffusion and oxidation of the wiring material formed on a wiring disposed in a lower layer of the capacitor element.

A method includes forming an insulating film over a substrate by introducing a cyclic siloxane compound having a cyclic siloxane as a skeleton and having at least one volatile hydrocarbon group bonded to a side chain, and a silicon-containing compound into a plasma, and converting the insulating film to a porous insulating film by adding energy to the insulating film. The silicon-containing compound is decomposed using less energy as compared with the skeleton of the cyclic siloxane compound, the volatile hydrocarbon group, and the bond between the cyclic siloxane compound and the volatile hydrocarbon group.
