Abstract:
A method of producing a chip scale package is disclosed. The method includes dicing a wafer into a plurality of chip arrays, each array including two or more integrated circuit chips. The method further includes mounting each array on a substrate and dicing each array, attached to the substrate, into individual chip scale packages, each individual chip scale package including only one integrated circuit chip.
Abstract:
A method for manufacturing integrated circuit packages (100, 200, 300) and a muli-chip integrated circuit package (100, 200, 300) are disclosed. A first die (110) is attached onto a first side of a set of leads of a leadframe (130), an adhesive (350) is applied onto the set of leads at a second side opposite to the first side. A second die (120) is attached onto the adhesive (350). The adhesive fills into the gaps between the leads. The adhesive is then cured. The adhesive attaching the second die fills the a s between the leads so that to avoid formation of internal cavities in the package
Abstract:
A semiconductor package including a first substrate having a die receiving area, a first adhesive layer, a window opening, and a plurality of conductive traces, a first semiconductor die having two sides and with an electrically active side mounted to the substrate through the first adheisve layer, a second adhesive layer having a first side attached to an electrically inactive side of the first semiconductor die, a second substrate having a die receiving area and a plurality of conductive traces and terminals, a last adhesive layer having a first side attached to a side of the second substrate with the terminals, a last semiconductor die having two sides and with an electrically inactive side being mounted to the second side of the third adhesive layer, and an electrically active side being electrically coupled to the conductive traces of the first or second substrate directly or through a redistribution device, and an encapsulant to encapsulate the semiconductor dies and electrical coupling, and signal transferring interconnects to transfer an electrical signal from the conductive traces to the exterior of the package.

Abstract:
A method of packaging a microchip device, an interposer for packaging, and a packaged microchip device. An interposer (7) is placed on microchip devices (1). The interposer (7) comprises an aperture (11) which extends from the interposer surface where external electrical contacts (9) are located to the surface of the microchip devices (1). Electrical contacts (3) on the microchip device surface are accessible thorough the aperture (11) in order to electrically connect the electrical contacts (3) with the external electrical contacts (9) of the interposer (7). The aperture (11) is divided into at least two openings or aperture regions, separated by a bridge (18). This facilitates the handling of the interposer (7).

The interposer (7) comprises separate openings or aperture regions, in particular separated by a bridge (19), which extend from the interposer surface where the external contacts (9) are located into the interposer (7). This facilitates the handling of the finalised package and allows for satisfactory filling of the aperture (11) with filling material.
