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.

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.

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.

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.

In accordance with an embodiment, a molding apparatus comprises a screen having a planar top surface; a recess in the screen and extending below the planar top surface; a blade capable of traversing the planar top surface; and a molding compound applicator. Another embodiment is a method for molding. The method comprises providing a substrate in a confined volume with an open top surface, applying molding compound in the confined volume, and traversing the open top surface with a blade thereby forming the molding compound to have a planar surface that is co-planar with the open top surface. The substrate has at least one semiconductor die adhered to the substrate.
