A semiconductor device includes a silicon layer, a metal silicide layer arranged directly on the silicon layer, and a solder layer arranged directly on the metal silicide layer.

A contact pad includes a solder-wettable porous network (310) which wicks the molten solder (130) and thus restricts the lateral spread of the solder, thus preventing solder bridging between adjacent contact pads.

Embodiments herein describe techniques for bonded wafers that includes a first wafer bonded with a second wafer, and a stress compensation layer in contact with the first wafer or the second wafer. The first wafer has a first stress level at a first location, and a second stress level different from the first stress level at a second location. The stress compensation layer includes a first material at a first location of the stress compensation layer that induces a third stress level at the first location of the first wafer, a second material different from the first material at a second location of the stress compensation layer that induces a fourth stress level different from the third stress level at the second location of the first wafer. Other embodiments may be described and/or claimed.

Packaged semiconductor components having substantially rigid support member are disclosed. The packages can include a semiconductor die and a support member proximate to the semiconductor die. The support member is at least substantially rigid. The packages can further include an adhesive between the support member and the semiconductor die and adhesively attaching the support member to the semiconductor die. The packages can also include a substrate carrying the semiconductor die and the support member attached to the semiconductor die.

A semiconductor manufacturing system comprises a laser and a heated bond tip and is configured to bond a die stack in a semiconductor assembly. The semiconductor assembly includes a wafer, manufacture from a material that is optically transparent to a beam emitted by the laser and configured to support a die stack comprising a plurality of semiconductor dies. A metal film is deposited on the wafer and heatable by the beam emitted by the laser. The heated bond tip applies heat and pressure to the die stack, compressing the die stack between the heated bond tip and the metal film and thermally bonding dies in the stack by heat emitted by the heated bond tip and the metal film when the metal film is heated by the beam emitted from the laser.

Capacitive coupling of integrated circuit die components and other conductive areas is provided. Each component to be coupled has a surface that includes at least one conductive area, such as a metal pad or plate. An ultrathin layer of dielectric is formed on at least one surface to be coupled. When the two components, e.g., one from each die, are permanently contacted together, the ultrathin layer of dielectric remains between the two surfaces, forming a capacitor or capacitive interface between the conductive areas of each respective component. The ultrathin layer of dielectric may be composed of multiple layers of various dielectrics, but in one implementation, the overall thickness is less than approximately 50 nanometers. The capacitance per unit area of the capacitive interface formed depends on the particular dielectric constants of the dielectric materials employed in the ultrathin layer and their respective thicknesses. Electrical and grounding connections can be made at the edge of the coupled stack.
