Claim 6:
7. The method of claim 1, wherein said forming a stacked film layer structure on a side of the semiconductor structure away from the wafer comprises:
forming a first insulation layer on the side of the semiconductor structure away from the wafer;
forming a first supporting layer on a side of the first insulation layer away from the semiconductor structure;
forming a second insulation layer on a side of the first supporting layer away from the semiconductor structure;
forming a second supporting layer on a side of the second insulation layer away from the semiconductor structure;
forming a third insulation layer on a side of the second supporting layer away from the semiconductor structure;
forming a dielectric layer on a side of the third insulation layer away from the semiconductor structure; and
forming a third supporting layer on a side of the dielectric layer away from the semiconductor structure;
wherein the third supporting layer is the first film layer.
