Definitions
- the invention relates to an integrated component with conductor tracks made of a copper-containing alloy and a metal-insulator-metal capacitor.
- L0 high-frequency circuits in BIPOLAR, BICMOS and CMOS technology require integrated capacitors with high voltage linearity, precisely adjustable capacitance values and, above all, low parasitic capacitances.
- the conventional MOS capacitors used to date have due to
- MIM capacitors metal-insulator-metal capacitors
- the object of the invention is to create an integrated component with conductor tracks made of a copper-containing alloy and an integrated metal-insulator-metal capacitor and to specify a method for its production.
- the metal-insulator-metal capacitor has an electrode which is formed in a metal plane for the conductor track. Since the dielectric intermediate layer and the metallization layer can be kept thin, the metal-insulator-metal capacitor can be integrated into an existing concept for producing an integrated component with passive components without great difficulty.
- the dielectric intermediate layer expediently serves as an etching stop. This ensures that the underlying copper-containing electrodes are not attacked by the etching medium. In addition, since the dielectric intermediate layer serving as an etch stop is not completely removed, short circuits between the metallization layer and the electrode underneath are avoided.
- the metal-insulator-metal capacitor is expediently produced in that a dielectric intermediate layer serving as an etch stop and then a metallization layer are deposited over the entire surface of the exposed electrode in the metal level for conductor tracks.
- the dielectric intermediate layer serves as an etching stop and is therefore essentially retained over the entire surface. This effectively suppresses short circuits at the edges of the metal-insulator-metal capacitor.

- the dielectric intermediate layer 11 is therefore also retained outside the metal-insulator-metal capacitor 7. Due to the extensive electrical separation of the upper electrode 12 and lower electrode 6, there is no risk of short circuits between the lower electrode 6 and the upper electrode 12.
- a further advantage is that the dielectric intermediate layer 11 and the upper electrode 12 are applied to a planarized surface can be. This ensures the planarity of the dielectric intermediate layer 11 and of the upper electrode 12.
- the interlayer dielectric 16 is deposited.
- the conductor track 14 and the vias 13 are then formed in the dual damascene process. Barriers 21 assume the role of the electrodes necessary for the deposition of the copper. When the trenches for the vias 13 are etched out, stop simultaneously on the upper electrode 12 of the metal-insulator-metal capacitor 7 and the conductor tracks 14.
- the dielectric intermediate layer 11 As a material for the dielectric intermediate layer 11, for example Si 3 N 4 or Si0 2 comes into question.
- materials with a high dielectric constant such as Ta 2 Os or Bi2Sr 3 TiO 3 and Ba x Sr ⁇ - x TiO 3, are also suitable for the dielectric intermediate layer 11, where 0 ⁇ x ⁇ 1 applies. It is particularly advantageous that the etching behavior of these materials does not have to be known in detail since the middle of the dielectric intermediate layer 11 stops.
- Ta and TaN, as well as silicides and materials such as Ti, TiN, TiW, W and WN X are suitable for the upper electrode 12, where 0 ⁇ x ⁇ 2 applies.
- Conductive materials such as Si, W, Cu, Au, Ag, Ti and Pt and alloys thereof can also be used for the upper electrode 12.
- the upper electrode 12 and the slide dielectric intermediate layer 11 covered by a protective layer made of SiN.
- This protective layer serves as a stop for the etching of the vias 13 and prevents the upper electrode 12 from being attacked during the etching of the vias 13.
- the upper electrode 12 is encapsulated to the side and thereby additionally insulated from the lower electrode 6.
- the proposed integrated component is particularly suitable for use in high-frequency technology.
