Abstract: A method for processing semiconductor dice comprises removing material from a surface of a semiconductor wafer to create a pocket surrounded by a sidewall at a lateral periphery of the semiconductor wafer, forming a film on a bottom of the pocket and securing semiconductor dice to the film in mutually spaced locations. A dielectric molding material is placed in the pocket over and between the semiconductor dice, material is removed from another surface of the semiconductor wafer to expose the film, bond pads of the semiconductor dice are exposed, redistribution layers in electrical communication with the bond pads of associated semiconductor dice are formed, and the redistribution layers and associated semiconductor dice are singulated along spaces between the semiconductor dice.

Abstract: Apparatuses and methods for providing thermal pathways from a substrate to a thermal bonding pad. The thermal pathways may be metal extensions of the thermal bonding pad that are disposed in channels formed in a backside passivation layer underneath the thermal bonding pad, and may be in direct contact with an underlying substrate. The thermal pathways may provide improved thermal dissipation from the substrate.

Abstract: Method for packaging a semiconductor die assemblies. In one embodiment, a method is directed to packaging a semiconductor die assembly having a first die and a plurality of second dies arranged in a stack over the first die, wherein the first die has a peripheral region extending laterally outward from the stack of second dies.

The underfill material is flowed after coupling the thermal transfer structure to the peripheral region of the first die such that the thermal transfer structure limits lateral flow of the underfill material.

Abstract: An apparatus, system, and a method of using the apparatus or system that includes a bladder positioned between tape and an adhesive layer configured to selectively connect the tape to a semiconductor device. The bladder includes one or more chambers that may be selectively expanded to move a portion of the bladder and adhesive layer away from the tape, which may enable the removal of the semiconductor device. The flow of fluid into each of the chambers may selectively expand the chambers. The chambers may have a substantially rounded upper profile or a substantially pointed upper profile. A material within the chambers may be heated to expand the chambers. A plurality of conduits may permit the flow of fluid into the chambers. The conduits may be inserted into the bladder. The chambers may be collapsed after expansion to enable the removal of a semiconductor device from the tape.
