A microelectronic substrate and method for manufacture. In one embodiment, the microelectronic substrate includes a body having a first surface, a second surface facing a direction opposite from the first surface, and a plurality of voids in the body between the first and second surfaces. The voids can extend from the first surface to a separation region beneath the first surface. At least one operable microelectronic device is formed at and/or proximate to the first surface of the substrate material, and then a first stratum of the microelectronic substrate above the separation region is separated from a second stratum of the microelectronic substrate below the separation region. The first stratum of the microelectronic substrate can be further separated into discrete microelectronic dies before the first stratum is separated from the second stratum. In one aspect of this embodiment, the substrate can support a film and microelectronic devices can be formed in the film and/or in the substrate.
摘要:
The exposed portions of the leads of a semiconductor chip package are first bent in a forming process so that the ends of the leads are in proper positions to be attached to and electrically connected to contacts on a printed circuit board. Intermediate portions of the leads between the distal ends and the package body for connection to the printed circuit board and the package body are enclosed and fixed in position by a carrier body to hold the leads in position and to reduce the effects of any bending in destroying the coplanarity of the distal lead ends of the package. The package with the carrier body may be mounted onto the printed circuit board without first removing the carrier body. After the distal ends of the leads have been soldered to the printed circuit board, the carrier body is then removed.

A method of fabricating an electronic assembly includes fabricating first and second interconnects. The first interconnect is adapted to interconnect a first die to a substrate. The second interconnect is adapted to interconnect the first die to a second die. The method further includes assembling the first die, the second die, and the substrate together such that the first die is disposed above the substrate, and the second die is disposed below the first die.
摘要:
An elongated bonding pad comprises two areas, a bonding area and an elongated probing area. The bonding area is located on the edge of an integrated circuit device for wire bonding. The elongated probing area is located on the inner area of the device. The long dimension of the elongated probing area is large enough for carrying a probing mark and the short dimension of the probing area is electrically and mechanically connected to the bonding area. Such elongated bonding pad can reduce the possibility of bonding wire open failures caused by wafer sort probing and increase the device's capacity of hosting more electrical components.
摘要:
A method for testing a lead connection to an integrated circuit chip is disclosed. The method comprises the steps of: (a) applying heat to an exposed surface of the integrated circuit chip; and (b) determining the heat transferred from the integrated circuit chip to a lead. Rapid transfer of heat to the lead indicates a valid connection between the integrated circuit chip and the electrical lead. Slow, non-uniform, or inadequate transfer of heat to the lead indicates an insufficiency or failure in the electrical connection between the integrated circuit and the lead. Determination of the heat transferred from the integrated circuit chip to the lead can be by any appropriate method. For example, the temperature of the lead can be determined using temperature probe, a liquid crystal display, or an electronically or visually scanned infrared display.
摘要:
A system for securing and electrically connecting a semiconductor chip to a body of passive substrate. The semiconductor chip and the substrate are both provided with bonding pads or bonding areas. The bonding pads or areas are located so that when a chip is placed next to the substrate, at least some of the bonding pads on the chip are aligned with corresponding bonding areas on the substrate. Micro-pins in the shape of straight wires, stubs or loops are used to electrically connect some of the bonding pads on the chip to corresponding areas on the substrate thereby electrically connecting them and also securely bonding the chip to the substrate. In the preferred embodiment, epoxy is used to further strengthen the physical bonding between the chip and the substrate. The wicking action of the micro-pins reduces bridging of solder across adjacent micro-pins.

A novel semiconductor chip cooling apparatus includes at least one semiconductor die packaged according to a TAB design. A support structure supports the die, and a dike is connected to the support structure and the TAB tape to form a cavity impervious to liquid and air. Input and output means are connected to the cavity. Fluid means circulate throughout the cavity and utilize the input and output means to directly cool the die during operation of the semiconductor die. Heat spreading means may be positioned below the die to increase the amount of surface area which contacts the fluid means, thereby cooling the die more efficiently.

Systems that provide integrated circuit device circuitry having an integrated optical-electronic interface for high-speed off-device communications are provided. An optical-electronic interface may be incorporated into an integrated circuit device, freeing up some or all of the electrical I/O pins of the integrated circuit device. Transceiver I/O channels may be provided on an integrated circuit device that can be switched between electrical and optical transceiver I/O channels.
