Abstract (en)

[origin: WO03058704A1] The invention relates to a method for producing a protection for the chip edges of electronic components that are not provided with a housing, according to which semiconductor chips provided with a laterally open bonding channel are mounted on a substrate with a tape interposed between. The invention further relates to a system for protecting chip edges. The aim of the invention is to provide a method which is easy to carry out and to provide a system for the secure protection of chip edges/corners. This aim is achieved by using for the assembly of the semiconductor chip on the substrate a tape whose cross- section is smaller than the cross-section of the semiconductor so that between the semiconductor and the substrate, along its outer edge, a peripheral recessed section is formed as a capillary. After establishment of the electrical connections between the semiconductor and the substrate, in a first step, a flowable encapsulation material is introduced into the bonding channel by wire-bonding until the encapsulation material evenly encloses the borders of the semiconductor chip. In a second step, the bonding channel is completely filled with the encapsulation material.
