Abstract:
In accordance with an embodiment, a structure comprises a substrate having a first area and a second area; a through substrate via (TSV) in the substrate penetrating the first area of the substrate; an isolation layer over the second area of the substrate, the isolation layer having a recess; and a conductive material in the recess of the isolation layer, the isolation layer being disposed between the conductive material and the substrate in the recess.
Abstract:
A composite carrier structure for manufacturing semiconductor devices is provided. The composite carrier structure utilizes multiple carrier substrates, e.g., glass or silicon substrates, coupled together by interposed adhesive layers. The composite carrier structure may be attached to a wafer or a die for, e.g., backside processing, such as thinning processes. In an embodiment, the composite carrier structure comprises a first carrier substrate having through-substrate vias formed therethrough. The first substrate is attached to a second substrate using an adhesive such that the adhesive may extend into the through-substrate vias.
Abstract:
A system and method for determining underfill expansion is provided. An embodiment comprises forming cover marks along a top surface of a substrate, attaching a semiconductor substrate to the top surface of the substrate, placing an underfill material between the semiconductor substrate and the substrate, and then using the cover marks to determine the expansion of the underfill over the top surface of the substrate. Additionally, cover marks may also be formed along a top surface of the semiconductor substrate, and the cover marks on both the substrate and the semiconductor substrate may be used together as alignment marks during the alignment of the substrate and the semiconductor substrate.
Abstract:
A method includes providing an interposer wafer including a substrate, and a plurality of through-substrate vias (TSVs) extending from a front surface of the substrate into the substrate. A plurality of dies is bonded onto a front surface of the interposer wafer. After the step of bonding the plurality of dies, a grinding is performed on a backside of the substrate to expose the plurality of TSVs. A plurality of metal bumps is formed on a backside of the interposer wafer and electrically coupled to the plurality of TSVs.
Abstract:
A device includes an interposer, which includes a substrate; and at least one dielectric layer over the substrate. A plurality of through-substrate vias (TSVs) penetrate through the substrate. A first metal bump is in the at least one dielectric layer and electrically coupled to the plurality of TSVs. A second metal bump is over the at least one dielectric layer. A die is embedded in the at least one dielectric layer and bonded to the first metal bump.
Abstract:
An apparatus includes a robot arm, and a plurality of guide pins mounted on the robot arm. Each of the plurality of guide pins includes a plurality of wafer supports at different levels, with each of the plurality of wafer supports configured to support and center a wafer having a size different from wafers configured to be supported and centered by remaining ones of the plurality of wafer supports.
Abstract:
A system and method for a semiconductor molding chamber is disclosed. An embodiment comprises a top molding portion and a bottom molding portion that form a cavity between them into which a semiconductor wafer is placed. The semiconductor molding chamber has a first set of vacuum tubes which hold and fix the position of the semiconductor wafer and a second set of vacuum tubes which evacuate the cavity of extraneous ambient gasses. The encapsulant may then be placed over the semiconductor wafer in order to encapsulate the semiconductor wafer.
