    摘要: A through hole (114) is formed in a wafer (104) comprising a semiconductor substrate (110). A seed layer (610) is sputtered on the bottom surface of the wafer. The seed is not deposited over the through hole's sidewalls adjacent the top surface of the wafer. A conductor (810) is electroplated into the through hole. In another embodiment, a seed is deposited into an opening in a wafer through a dry film resist mask (1110). The dry film resist overhangs the edges of the opening, so the seed is not deposited over the opening's sidewalls adjacent the top surface of the wafer. In another embodiment, a dielectric (120) is formed in an opening in a semiconductor substrate (110) by a non-conformal physical vapor deposition (PVD) process that deposits the dielectric on the sidewalls but not the bottom of the opening. A seed (610) is formed on the bottom by electroless plating. A conductor (810) is electroplated on the seed. In another embodiment, a dielectric (2910) is formed in the opening to cover the entire surface of the opening. A non-conformal layer (120) is deposited by PVD over the sidewalls but not the bottom of the opening. The dielectric (2910) is etched off the bottom with the non-conformal layer (120) as a mask. A seed (610) is formed on the bottom by electroless plating. The non-conformal layer can be formed by electroplating. It can be tantalum deposited by electroplating, then anodized. Other embodiments are also provided.

    摘要: The present invention relates to a non-contact holder for substantially planar workpieces, particularly suited for holding thin workpieces without substantial distortion. The present invention includes a cylindrical chuck having a gas inlet orifice positioned at an oblique. The introduction of pressurized gas creates a vortex and vacuum attraction holding a wafer in close proximity to the chuck while the gas exiting from the chuck prevents contact between wafer and chuck. Small diameter chucks located in close proximity help the present invention avoid distortion when processing very thin workpieces. The gas exiting from the chuck of the present invention exits preferentially in a certain angular direction. Chucks are arranged on the wafer holder such that exiting gas is preferentially directed radially towards the periphery of the holder and that exiting gas is directed between adjacent chucks, not directly at another nearby chuck. Chucks on the periphery of the holder are positioned have the gas exiting therefrom towards the periphery of the holder and overlapping the gas flow from immediately adjacent chucks. Chucks on the periphery of the holder are located as close together as feasible. The combination of overlapping gas flow and close proximity creates a gas shield on the boundary of the wafer holder.

    摘要: A packaging substrate (310) includes a semiconductor interposer (120) and at least one other intermediate substrate (110), e.g. a BT substrate. The semiconductor interposer has first contact pads (136C) attachable to dies (124) above the interposer, and second contact pads (340) attachable to circuitry below the interposer. Through vias (330) are made in the semiconductor substrate (140) of the interposer (120). Conductive paths going through the through vias connect the first contact pads (136C) to the second contact pads (340). The dies (124) are attached to the interposer after the attachment of the interposer to the BT substrate. In sequential soldering operations, the solder hierarchy is maintained by dissolving some material (e.g. copper) in the solder during soldering to raise the solder's melting temperature. For example, all of the solders may initially have the same melting temperature, but each solder's melting temperature is increased during soldering to prevent the solder from melting in the subsequent soldering operations.
