Semiconductor device assemblies with solderless interconnects, and associated systems and methods are disclosed. In one embodiment, a semiconductor device assembly includes a first conductive pillar extending from a semiconductor die and a second conductive pillar extending from a substrate. The first conductive pillar may be connected to the second conductive pillar via an intermediary conductive structure formed between the first and second conductive pillars using an electroless plating solution injected therebetween. The first and second conductive pillars and the intermediary conductive structure may include copper as a common primary component, exclusive of an intermetallic compound (IMC) of a soldering process. A first sidewall surface of the first conductive pillar may be misaligned with respect to a corresponding second sidewall surface of the second conductive pillar. Such interconnects formed without IMC may improve electrical and metallurgical characteristics of the interconnects for the semiconductor device assemblies.

A method for bonding a contact surface of a first substrate to a contact surface of a second substrate comprising of the steps of: positioning the first substrate on a first receiving surface of a first receiving apparatus and positioning the second substrate on a second receiving surface of a second receiving apparatus; establishing contact of the contact surfaces at a bond initiation site; and bonding the first substrate to the second substrate along a bonding wave which is travelling from the bond initiation site to the side edges of the substrates, wherein the first substrate and/or the second substrate is/are deformed for alignment of the contact surfaces.

A method for bonding a contact surface of a first substrate to a contact surface of a second substrate comprising of the steps of: positioning the first substrate on a first receiving surface of a first receiving apparatus and positioning the second substrate on a second receiving surface of a second receiving apparatus; establishing contact of the contact surfaces at a bond initiation site; and bonding the first substrate to the second substrate along a bonding wave which is travelling from the bond initiation site to the side edges of the substrates, wherein the first substrate and/or the second substrate is/are deformed for alignment of the contact surfaces.

A machine vision system for substrate alignment includes first and second illumination sources (11, 12), first and second reflectors (21, 22), first and second objective lenses (31, 32) and first and second detectors (41, 42), each of which pair is symmetric with respect to an X-axis. Light beams emitted from the first and second illumination sources are irradiated on and reflected by respective substrates (1, 2), amplified by the respective objective lenses and received and detected by the respective detectors. An alignment apparatus is also disclosed. Disposing each of the pair of the first and second illumination sources, the first and second reflectors, the first and second objective lenses and the first and second detectors in symmetry with respect to the X-axis results in a significantly reduced footprint of the machine vision system along the orientation of lens barrels of the objective lenses and hence an expanded detection range thereof and improved alignment efficiency and accuracy.

A bond chuck having individually-controllable regions, and associated systems and methods are disclosed herein. The bond chuck comprises a plurality of individual regions that are movable relative to one another in a longitudinal direction. In some embodiments, the individual regions include a first region having a first outer surface, and a second region peripheral to the first region and including a second outer surface. The first region is movable in a longitudinal direction to a first position, and the second region is movable in the longitudinal direction to a second position, such that in the second position, the second outer surface of the second region extends longitudinally beyond the first outer surface of the first region. The bond chuck can be positioned proximate a substrate of a semiconductor device such that movement of the first region and/or second region affect a shape of the substrate, which thereby causes an adhesive on the substrate to flow in a lateral, predetermined direction.

A bond chuck having individually-controllable regions, and associated systems and methods are disclosed herein. The bond chuck comprises a plurality of individual regions configured to be individually heated independent of one another. In some embodiments, the individual regions include a first region configured to be heated to a first temperature, and a second region peripheral to the first region and configured to be heated to a second temperature different than the first temperature. In some embodiments, the bond chuck further comprises (a) a first coil disposed within the first region and configured to heat the first region to the first temperature, and (b) a second coil disposed within the second region and configured to heat the second region to the second temperature. The bond chuck can be positioned proximate a substrate of a semiconductor device such that heating the first region and/or second region affect the viscosity of an adhesive used to bond substrates of the semiconductor device to one another. Accordingly, heating the first region and/or the second region can cause the adhesive on the substrate to flow in a lateral, predetermined direction.
