    摘要: A method and apparatus for electrolytic plating of selected areas of printed circuit board traces is disclosed. The method is characterized by its elimination of the need for plating bus bars and plating contacts on the printed circuit board to facilitate a spot-plating process. In one embodiment, a printed circuit board substrate is provided which is at least partially conductive, such that a plating voltage may be applied to any one or more points on the substrate during a spot plating operation. In another embodiment, the substrate material is initially partially conductive, but following the spot-plating operation, is subjected to a curing treatment or the like to cause degeneration of the substrate's conductivity. Carbon-impregnated polyimide, partially-cured polyimide, FR4 or FR5, with appropriate contaminants introduced therein are contemplated as materials suitable for a printed circuit board substrate in accordance with the invention. In another embodiment, the traces are first applied to the partially conductive substrate by an electroplating operation wherein an electroplating voltage is applied to the substrate such that the substrate itself serves as one terminal of the electroplating system.

    摘要: Logic circuitry formed in street areas between adjacent fabricated electronic devices may be used as auxiliary or redundant components to salvage one or more otherwise defective devices. Logic circuitry is selectively coupled to the defective device(s) to directly replace or facilitate the replacement of defective components on one or more fabricated devices, thereby resulting in a single operable electronic device. The invention may be used to increase the production yield of electronic devices, particularly, semiconductor integrated circuits. The invention permits the fabrication of discretionary wiring during the normal metalization of semiconductor layers to interconnect electronic devices at the same time as the formation of the normal wiring/circuitry of the devices.

    摘要: An IC module, such as a Multi-Chip Module (MCM), includes multiple IC dice, each having a test mode enable bond pad, such as an output enable pad. A fuse incorporated into the MCM's substrate connects each die's test mode enable bond pad to one of the MCM's no-connection (N/C) pins, and a resistor incorporated into the substrate connects the test mode enable bond pads to one of the MCM's ground pins. By applying a supply voltage to the test mode enable bond pads through the N/C pin, a test mode is initiated in the dice. Once testing is complete, the fuse may be blown, and a ground voltage applied to the test mode enable bond pads through the ground pins so the resistor disables the test mode in the dice and initiates an operational mode. As a result, dice packaged in IC modules may be tested after packaging. A method for performing such testing once the test mode has been initiated and for repairing any failing elements found during testing includes providing test signals to the dice, receiving response signals from the dice, evaluating the response signals to identify any failing elements in the dice, programming the failing elements' addresses into anti-fuses in the dice with a programming voltage, confirming that the addresses are programmed by determining the resistance of the anti-fuses, re-testing the dice, receiving response signals from the re-tested dice, and evaluating the response signals to confirm all repairs.

    摘要: A circuit transfers data in an array of memory cells arranged in rows and columns. The circuit includes a plurality of row lines, a plurality of pairs of complementary digit lines, and an array of memory cells, each memory cell having a control terminal coupled to one of the row lines and a data terminal coupled to one of the complementary digit lines of one of the pairs of complementary digit lines responsive to a row enable signal on the row line of the row corresponding to the memory cell. A plurality of sense amplifiers are included in the circuit, each sense amplifier coupled to an associated pair of first and second complementary digit lines which senses a voltage differential between the first and second complementary digit lines and, in response to the sensed voltage differential, drives the first and second complementary digit lines to voltage levels corresponding to complementary logic states. A plurality of equilibration circuits are also included in the circuit, each equilibration circuit coupled between one of the pairs of complementary digit lines and operable to equalize the voltage level on each pair of complementary digit lines to a predetermined level responsive to an equilibration signal. A control circuit is coupled to the plurality of row lines and the equilibration circuits. The control circuit is operable to: write a pattern of data to an initial row of the memory array; generate the equilibrate signal; apply a row enable signal to the row line of the memory cells in the initial row; terminate the row enable signal for the initial row; apply a row enable signal to the row line to which the memory cells in another row are connected; terminate the row enable signal for the another row; and generate the equilibrate signal.

    摘要: A new inverting output driver circuit is disclosed that reduces electron injection into the substrate by the drain of the circuit's pull-up field effect transistor. This is accomplished by adding additional circuitry that allows the gate voltage of the pull-up transistor to track the source voltage. The output circuit makes use of an inverter having an output node (hereinafter the intermediate node) coupled to V.sub.CC through a first P-channel FET, and to ground through first and second series coupled N-channel FETs, respectively. The gates of the P-channel FET and the first N-channel FET are coupled to and controlled by an input node. The inverter output node controls the gate of third N-channel FET, through which a final output node is coupled to V.sub.CC. The intermediate node is coupled to the final output node through a fourth N-channel FET, the gate of which is held at ground potential. The gate of the second N-channel FET is coupled to V.sub.CC through a second P-channel FET and to the final output node through a fifth N-channel FET which has much greater drive than the second P-channel FET; the gates of both the second P-channel FET and the fifth N-channel FET also being held at ground potential. Certain obvious variations of the circuit are possible. For example, the function of the first and second N-channel FETs may be reversed. In addition, the second P-channel FET functions as a resistor, and may be replaced with any device which functions as a resistor.
