Chip-scale package and carrier for use therewith
Abstract
A carrier for use in a chip-scale package includes a film with at least one aperture defined therethrough. The aperture, which is alignable with a corresponding bond pad of a semiconductor device over which the carrier is to be positioned, is at least partially filled with conductive material. A contact on a surface of the carrier may communicate with the conductive material within the aperture. A conductive bump may be disposed adjacent the contact. The carrier may be positioned on a semiconductor device to form a chip-scale package. Such a chip-scale package may include a semiconductor device invertedly disposed over the carrier with bond pads of the semiconductor device being substantially aligned with apertures of the carrier.
