Abstract: A non-volatile memory provides a signal hold circuit (30) which uses a FAMOS (32) instead of an input transistor of a ratiod inverting amplifier and outputs a change in a threshold value of the FAMOS, for the purpose of reducing the number of elements of the signal hold circuit. FAMOSs for programming and latching are provided respectively, and the FAMOSs are interconnected to each other at their floating gate electrodes to isolate the signal hold circuit and a program circuit (40) and hence prevent a DC current path from being formed between those two circuits, for the purpose of miniaturization of a memory cell.

Abstract: A test cell (12) provides boundary scan testing in an integrated circuit (10). The test cell (12) comprises two memories, a flip-flop (24) and a latch (26), for storing test data. A first multiplexer (22) selectively connects one of a plurality of inputs to the flip-flop (24). The input of the latch (26) is connected to output of the flip-flop (24). The output of the latch (26) is connected to one input of a multiplexer (28), the second input to the multiplexer (28) being a data input (DIN) signal. A control bus (17) is provided for controlling the multiplexers (22, 28), flip-flop (24) and latch (26). The test cell allows input data to be observed and output data to be controlled simultaneously. This architecture allows propagation delays between devices to be determined. A driving device (264) toggles its output on a first clock edge. On a subsequent clock edge, the receiving circuit (266) samples its input. The sampled input may be scanned out and compared to the toggled value to determine whether the signal propagated between the first and second clock edges.

Abstract: A line protection circuit for an ISDN device includes a pair of identical, field effect transistors (40, 42) connected between the device and opposite terminals of one winding (44) of an isolation transformer. Each device has one N region (46) connected to an output line (36) from the ISDN device, a second N region (48) connected to one winding terminal, a grounded channel or P region and a gate (52) connected to a source of positive logic voltage. During normal operation, the FETs pass current provided by a constant current source within the ISDN device without attenuation. If a power surge occurs elsewhere in the ISDN network, the voltage at one of the FETs (40) is being clamped to ground while the voltage at the other FET (42) rises only until FET cut-off occurs. If power is removed from the FETs, at least one PN junction will always be reverse biased to isolate the protected ISDN device from the remainder of the network.

Abstract: The present invention is a high efficiency bi-directional spatial power combiner for extremely high frequency signals. In one embodiment, orthogonally polarized electro-magnetic waves are used to isolate signals going into and out of a planar array of amplifiers. A dual mode horn transmits vertically polarized fields to a MMIC planar array of amplifiers. Vertically polarized array elements receive the signals, amplify them, and retransmit back to the horn using horizontally polarized array elements. An ortho-mode transducer on the horn provides isolation for the two polarized signals. The backside of the array can be used for a heat sink, and to provide access for DC biasing of the array elements. In a second embodiment, monolithic grid oscillators are used in lieu of power amplifiers with orthogonal polarization array elements. The input signal and the output signal are of the same polarization. A circulator is used in lieu of an ortho-mode transducer to isolate the input signal from the output signal.

Abstract: By using a vapor containing alkoxyfluorosilane as a main component, a silicon oxide film containing fluorine is formed on a substrate (104) at a temperature of 200°C or less in a reaction chamber (101) having a predetermined temperature and a predetermined pressure. For example, triethoxyfluorosilane may be supplied to the chamber (101) from a bubbler (107) and steam may be supplied from a bubbler (108). In addition, an organic film such as a photoresist film (304) can be used as a mask to selectively form the silicon oxide film. Although the silicon oxide film can be formed at a very low temperature of 30°C, the film has a water content smaller than that of a silicon oxide film formed at a temperture of 250°C by a conventional method. In addition, the film properties of the silicon oxide film are better than those of the silicon oxide film formed by the conventional method. Furthermore, a two-layered aluminum wiring structure can be easily formed by a selective growing method.
