    Abstract: A temporary substrate (901) having an array of first solder pads (192) is bonded to the front side of a first substrate (101) by reflowing an array of first solder balls (250). The first substrate (101) is thinned by removing the back side, and an array of second solder pads (142) is formed on the back side surface of the first substrate (101). The assembly of the first substrate (101) and the temporary substrate (901) is diced to form a plurality of stacks, each including an assembly of a first semiconductor chip (100) and a handle portion (900). A second semiconductor chip (200) is bonded to an assembly through an array of the second solder balls (150). The handle portion (900) is removed from each assembly by reflowing the array of the first solder balls (250), while the array of the second solder balls (150) does not refiow. The assembly is subsequently mounted on a packaging substrate (300) employing the array of the first solder balls (250).

    Abstract: The present disclosure provides a thermo-mechanically reliable copper TSV and a technique to form such TSV during BEOL processing. The TSV constitutes an annular trench which extends through the semiconductor substrate. The substrate defines the inner and outer sidewalls of the trench, which sidewalls are separated by a distance within the range of 5 to 10 microns. A conductive path comprising copper or a copper alloy extends within said trench from an upper surface of said first dielectric layer through said substrate. The substrate thickness can be 60 microns or less. A dielectric layer having interconnect metallization conductively connected to the conductive path is formed directly over said annular trench.

    Abstract: A TSV can be formed having a top section via formed through the top substrate surface and a bottom section via formed through the bottom substrate surface. The top section cross section can have a minimum cross section corresponding to design rules, and the top section depth can correspond to a workable aspect ratio. The top section via can be filled or plugged so that top side processing can be continued. The bottom section via can have a larger cross section for ease of forming a conductive path therethrough. The bottom section via extends from the back side to the bottom of the top section via and is formed after the substrate has been thinned. The TSV can be completed by forming a conductive path after removing sacrificial fill materials from the joined top and bottom section vias.

    Abstract translation: 可以形成TSV,其具有通过顶部衬底表面形成的顶部截面,以及通过底部衬底表面形成的底部截面。 顶部截面可以具有对应于设计规则的最小横截面,并且顶部截面深度可对应于可工作的纵横比。 顶部通孔可以被填充或插入,以便可以继续顶部处理。 底部通孔可以具有更大的横截面,以便于形成穿过其中的导电路径。 底部部分通孔从顶部部分通孔的背面延伸到底部,并且在基板变薄之后形成。 可以通过在从接合的顶部和底部部分通孔去除牺牲填充材料之后形成导电路径来完成TSV。
