Abstract:
Microfeature workpieces having alloyed conductive structures, and associated methods are disclosed. A method in accordance with one embodiment includes applying a volume of material to a bond pad of a microfeature workpiece, with the volume of material including a first metallic constituent and the bond pad including a second constituent. The method can further include elevating a temperature of the volume of material while the volume of material is applied to the bond pad to alloy the first metallic constituent and the second metallic constituent so that the first metallic constituent is alloyed generally throughout the volume of material. A thickness of the bond pad can be reduced from an initial thickness T1 to a reduced thickness T2.
Abstract:
Semiconductor devices with porous insulative materials are disclosed. The porous insulative materials may include a consolidated material with voids dispersed therethrough. The voids may be defined by shells of microcapsules. The voids impart the dielectric materials with reduced dielectric constants and, thus, increased electrical insulation properties.
Abstract:
Interconnect structures for stacked dies, including penetrating structures for through-silicon vias, and associated systems and methods are disclosed. A system in accordance with a particular embodiment includes a first semiconductor substrate having a first substrate material, and a penetrating structure carried by the first semiconductor substrate. The system further includes a second semiconductor substrate having a second substrate material with a preformed recess. The penetrating structure of the first semiconductor substrate is received in the recess of the second semiconductor substrate and is mechanically engaged with the recess and secured to the second semiconductor substrate.
Abstract:
Methods and systems for imaging and cutting semiconductor wafers and other microelectronic device substrates are disclosed herein. In one embodiment, a system for singulating microelectronic devices from a substrate includes an X-ray imaging system having an X-ray source spaced apart from an X-ray detector. The X-ray source can emit a beam of X-rays through the substrate and onto the X-ray detector, and X-ray detector can generate an X-ray image of at least a portion of the substrate. A method in accordance with another embodiment includes detecting spacing information for irregularly spaced dies of a semiconductor workpiece. The method can further include automatically controlling a process for singulating the dies of the semiconductor workpiece, based at least in part on the spacing information. For example, individual dies can be singulated from a workpiece via non-straight line cuts and/or multiple cutter passes.
