A multi-chip packaging substrate having a non-sticking test structure consists of a plurality of non-sticking test spots formed in the periphery zone outside the chip-packaging zone of a multi-chip packaging substrate. Each of these non-sticking test spots is electrically connected to an adjacent one of a plurality of chip pads respectively in the chip packaging zone through a plurality of conductive traces while there are no electrical connections connected one another among the chip pads.

A semiconductor package is disclosed including a plurality semiconductor die mounted on stacked and bonded layers of substrate, for example polyimide tape used in tape automated bonding processes. The tape may have a plurality of repeating patterns of traces and contact pads formed thereon. The traces each include aligned interconnect pads on the respective top and bottom surfaces of the substrate for bonding the traces of one pattern to the traces of another pattern after the patterns have been singulated from the substrate, aligned and stacked. Semiconductor die such as flash memory and a controller die are mounted on the traces of the respective patterns on the substrate. In order for the controller die to uniquely address a specific flash memory die in the stack, a group of traces on each substrate supporting the memory die are used as address pins and punched in a unique layout relative to the layout of the traces other substrates. By providing each flash memory semiconductor die on a substrate with a unique layout of address traces, each memory die may be selectively addressed by the controller die.

A semiconductor die and semiconductor package formed therefrom, and methods of fabricating the semiconductor die and package, are disclosed. The semiconductor die includes an edge formed with a plurality of corrugations defined by protrusions between recesses. Bond pads may be formed on the protrusions. The semiconductor die formed in this manner may be stacked in the semiconductor package in staggered pairs so that the die bond pads on the protrusions of a lower die are positioned in the recesses of the upper die.

A semiconductor chip package is formed to be capable of reducing moisture erosion by configuring the bonding finger, the plating-conduction-line, and the trace on the chip carrier therein in such a way that the length of path for moisture to penetrate and to reach the bonding finger through a plating-conduction-line is significantly longer than those implemented in a conventional chip package.

A BGA (Ball Grid Array) package is proposed, which is characterized by the provision of an interdigitated power/ground ring layout scheme. By this layout scheme, the power ring and the ground ring are each formed with a line portion and a plurality of toothed portions; with the toothed portions of the power ring being are interdigitated with the toothed portions of the ground ring. Moreover, the power/ground vias are all connected to the toothed portions of the power ring and the ground ring, thereby leaving the line portions of the power ring and the ground ring unoccupied by the power/ground vias, allowing the routability of power/ground wires to be higher than the prior art. Moreover, solder bask is formed in such a manner as to cover all the toothed portions of the ground ring, so that power wires can be prevented from being short-circuited to the ground ring due to sagging. Further, the toothed portions of the power ring and the ground ring are large in area, whereby two or more power vias or ground vias can be gathered together to increase the overall electrical performance, and whereby the packaged chip can be increased in heat-dissipation efficiency.

A semiconductor device is disclosed including an electromagnetic radiation shield. The device may include a substrate having a shield ring defined in a conductance pattern on a surface of the substrate. One or more semiconductor die may be affixed and electrically coupled to the substrate. The one or more semiconductor die may then be encapsulated in molding compound. Thereafter, a metal may be plated around the molding compound and onto the shield ring to form an EMI/RFI shield for the device.

A semiconductor die package is disclosed. An example of the semiconductor package includes a first group of semiconductor die interspersed with a second group of semiconductor die. The die from the first and second groups are offset from each other along a first axis and staggered with respect to each other along a second axis orthogonal to the first axis. A second example of the semiconductor package includes an irregular shaped edge and a wire bond to the substrate from a semiconductor die above the lowermost semiconductor die in the package.

The present invention is a method for identifying defective elements in array molding of semiconductor packaging for mini BGA packaging substrate which comprises a circuit zone and a periphery zone. The method of the present invention is first to form a plurality of package sites disposed in array in the circuit zone, and to form a plurality of marks in a periphery zone. When a defective element is found in the package sites, a symbol is put at the mark or an electronic file is employed to record the location of the defective element, thereby, the defective element in the package sites of the molding array in the circuit zone can be identified.
