Abstract: 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.

Abstract: 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.

Abstract: 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.
