| 摘要 |
The invention provides methods and structures for fabricating a semiconductor structure and particularly for forming a semiconductor structure with improved planarity for achieving a bonded semiconductor structure comprising a processed semiconductor structure and a number of bonded semiconductor layers. Methods for forming semiconductor structures include forming a dielectric layer over a non-planar surface of a processed semiconductor structure, planarizing a surface of the dielectric layer on a side thereof opposite the processed semiconductor structure, and attaching a semiconductor structure to the planarized surface of the dielectric layer. Semiconductor structures include a dielectric layer overlaying a non-planar surface of a processed semiconductor structure, and a masking layer overlaying the dielectric layer on a side thereof opposite the processed semiconductor structure. The masking layer includes a plurality of mask openings over conductive regions of the non-planar surface of the processed semiconductor structure.
