Claim 0:
1. A method for fabricating a semiconductor device, comprising:
providing a first semiconductor structure which has a top surface; and
forming a first connecting structure comprising a first connecting insulating layer on the first semiconductor structure, a plurality of first connecting contacts in the first connecting insulating layer, and a plurality of first supporting contacts in the first connecting insulating layer and alternating with the first connecting contacts;
wherein the first connecting layer is formed by the steps of:
forming a bottom insulating layer on the first semiconductor structure at a position that a bottom surface of the bottom insulating layer is in direct contact with the top surface of the first semiconductor structure;
forming a first middle insulating layer formed on the first bottom insulating layer at a position that a bottom surface of the first middle insulating layer is in direct contact with a top surface of the first bottom insulating layer; and
forming a first top insulating layer formed on the first middle insulating layer at a position that a bottom surface of the first top insulating layer is in direct contact with a top surface of the first middle insulating layer;
wherein each of the first connecting contacts, which is a one piece solid member, is extended in the first connecting layer to penetrate the first top insulating layer, the first middle insulating layer, and the first bottom insulating layer, such that a height of each of the first connecting contacts is larger than an overall thickness of the first middle insulating layer and the first top insulating layer;
wherein each of first supporting contacts, which also is a one piece solid member, is embedded in the first top insulating layer that a height of each of first supporting contacts is not larger than a thickness of the first top insulating layer.
