An isolation structure for stacked dies is provided. A through-silicon via is formed in a semiconductor substrate. A backside of the semiconductor substrate is thinned to expose the through-silicon via. An isolation film is formed over the backside of the semiconductor substrate and the exposed portion of the through-silicon via. The isolation film is thinned to re-expose the through-silicon via, and conductive elements are formed on the through-silicon via. The conductive element may be, for example, a solder ball or a conductive pad. The conductive pad may be formed by depositing a seed layer and an overlying mask layer. The conductive pad is formed on the exposed seed layer. Thereafter, the mask layer and the unused seed layer may be removed.

A method of forming a device includes printing conductive patterns on a dielectric sheet to form a pre-ink-printed sheet, and bonding the pre-ink-printed sheet onto a side of a substrate. The conductive feature includes a through-substrate via extending from a first major side of the substrate to a second major side of the substrate opposite the first major side. A conductive paste is then applied to electrically couple conductive patterns to a conductive feature in the substrate.

A device for use with integrated circuits is provided. The device includes a substrate having a through-substrate via formed therethrough. Dielectric layers are formed over at least one side of the substrate and metallization layers are formed within the dielectric layers. A first metallization layer closest to the through-substrate via is larger than one or more overlying metallization layers. In an embodiment, a top metallization layer is larger than one or more underlying metallization layers. Integrated circuit dies may be attached to the substrate on either or both sides of the substrate, and either side of the substrate may be attached to another substrate, such as a printed circuit board, a high-density interconnect, a packaging substrate, an organic substrate, a laminate substrate, or the like.

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.
