Abstract: A bonding pad that has low parasitic capacitance and that transmits little or no stress to the underlying metal layer during bonding, along with a process for manufacturing it, is described. A key feature of this structure is that the damascene wiring directly below the bonding pad has been limited to its outer edges, that is it is formed in the shape of a hollow square. This limits overlap by the aluminum pad of the damascene wiring to the via hole area only. After a passivation layer, including suitable diffusion barriers, has been laid over the structure, it is over-filled with a suitable soft metal (typically copper or one of its alloys) and then planarized in the usual way. A via hole for communicating with the damascene wiring is then formed. This via can take the shape of a somewhat smaller hollow square or it can be formed from a series of individual vias arranged in the shape of a broken hollow square.

The damaged recombination region(s) may be formed by a damaging implant into a surface semiconductor layer, for example through an open portion of a doping mask, the opening portion created for example by removal of a dummy gate.

Abstract: A resist pattern (51) is formed only on buried silicon oxide films (2) on the whole surface of an alignment mark area (11A) and a trench (10C). With the resist pattern (51), preetching is performed by dry etching, to remove the silicon oxide film (2) on the whole of a memory cell area (11B) and part of a peripheral circuit area (11C) by a predetermined thickness. After removing the resist pattern (51), a silicon oxide film (3) and a silicon nitride film (4) are removed by CMP polishing, to provide a height difference between the highest portion and the lowest portion of the silicon oxide film (2A) which serves as an alignment mark. Thus, a semiconductor device with trench isolation structure which achieves a highly accurate alignment without deterioration of device performance and a method for manufacturing the semiconductor device can be provided.
