  • Publication number: 20040065868
    Abstract: A composite body produced by a reactive infiltration process that possesses high mechanical strength, high hardness and high stiffness has applications in such diverse industries as precision equipment and ballistic armor. Specifically, the composite material features a boron carbide filler or reinforcement phase, and a silicon component with a porous mass having a carbonaceous component. Potential deleterious reaction of the boron carbide with silicon during infiltration is suppressed by alloying or dissolving boron into the silicon prior to contact of the silicon infiltrant with the boron carbide. In a preferred embodiment of the invention related specifically to armor, good ballistic performance can be advanced by loading the porous mass or preform to be infiltrated to a high degree with one or more hard fillers such as boron carbide, and by limiting the size of the largest particles making up the mass.

  • Publication number: 20040065873
    Abstract: A system and method of use for determining a desired physical parameter relating to a load deployed by a movable vessel, in a predetermined plane, using a sensor disposed proximate the load underwater where the sensor produces a transmittable signal indicative of the desired physical parameter and communicates the signal, via a communication link, to a receiver that receives and indicates the pressure signal. A deployment frame may be used to further support the load. Once deployed, the load encounters water having changes in the detected physical parameter and the sensor sends a signal indicative of the changes such as to a controller or computer located on a movable vessel. These signals can be used to determine movement and positioning of the load, e.g. when positioning the load proximate an underwater structure.

  • Publication number: 20040065876
    Abstract: A photosensitive device with a photodiode and an amplifier is disclosed. The diode is in series with a feedback transistor which forces the voltage derived from the photocurrent to be a logarithmic function of the light intensity. A current mirror is provided which controls the bias current to the amplifier to be proportional to the photocurrent. This arrangement ensures that the amplifier, just as the voltage derived from the photocurrent, becomes faster with increasing light intensity and therefore prevents an unnecessarily high power consumption at low light intensities.

  • Publication number: 20040065879
    Abstract: A process via mismatch detecting device is disclosed. Because the vias in the detecting circuit of process via mismatch detecting device are mismatched while the vias between the metal layers of the chips are mismatched, by appropriately placing vias in detecting circuit of process via mismatch detecting device properly, metal lines of different metal layers in the detecting circuit can become short-circuited by mismatched vias, so as to output a voltage signal that is higher after vias mismatch and is regarded as the result of detecting via mismatch. Therefore, the direction and quantity of via mismatch between the metal layers in the chip are detected and monitored effectively, so as to optimize the process. Thus, the yield of process is increased and the cost is decreased.

  • Publication number: 20040065880
    Abstract: Method and apparatus for optically testing (e.g., using a laser beam) an operating integrated circuit (device under test—DUT) that actively control the operating temperature of the DUT. This is chiefly useful with flip-chip packaged ICs. The temperature of the DUT varies with its operating power consumption, and this fluctuation in temperature adversely affects the results obtained during optical probing or other optical testing. Furthermore, the DUT may be damaged if its temperature exceeds design limits. The temperature of the DUT is controlled by thermally contacting the exposed backside surface of the DUT die to a diamond film heat conductor, an associated heat sink structure, and at least one thermoelectric device. The thermoelectric device is controlled by a temperature sensor proximal to the DUT. By controlling the amount and direction of the electrical current supplied to the thermoelectric device in response to the sensed temperature, the temperature of the DUT is maintained.

    Abstract: By providing appropriate TFT structures arranged in various circuits of the semiconductor device in response to the functions required by the circuits, it is made possible to improve the operating performances and the reliability of a semiconductor device, reduce power consumption as well as realizing reduced manufacturing cost and increase in yield by lessening the number of processing steps. An LDD region of a TFT is formed to have a concentration gradient of an impurity element for controlling conductivity which becomes higher as the distance from a drain region decreases. In order to form such an LDD region having a concentration gradient of an impurity element, the present invention uses a method in which a gate electrode having a taper portion is provided to thereby dope an ionized impurity element for controlling conductivity accelerated in the electric field so that it penetrates through the gate electrode and a gate insulating film into a semiconductor layer.

    Abstract: The present invention provides a PMSCR (bridging modified lateral modified silicon controlled rectifier having first conductivity type) with a guard ring controlled circuit. The present invention utilizes controlled circuit such as switch to control functionally of guard ring of PMSCR. In normal operation, the switch is of low impedance such that the guard ring is short to anode and collects electrons to enhance the power-zapping immunity. Furthermore, during the ESD (electrostatic discharge) event, the switch is of high impedance such that the guard ring is non-functional. Thus, the PMSCR with guard ring control circuit can enhance both the ESD performance and the power-zapping immunity in the application of the HV (high voltage) pad.

    Abstract: A semiconductor device has a via-contact, a main wire having an end connected to the via-contact, and an extension extended in line with the main wire from the end of the main wire beyond the via-contact, the width of the extension being equal to or narrower than the width of the main wire. The extension prevents the end of the main wire from being rounded by an optical proximity effect, eliminates a contact defect or an open defect between the via-contact and the end of the main wire, and involves no widening of the main wire around the via-ntact, so that other via-contacts may be arranged in the vicinity of the via-contact in question without violating design rules.

    Abstract: In a method for forming a channel zone in field-effect transistors, a polysilicon layer is patterned above the channel zone to be formed. The polysilicon layer serves as a mask substrate for the subsequent doping of the channel zone. The expedient patterning of the polysilicon layer with holes in a gate region and pillars in a source region enables the channel zone to be doped more lightly. In another embodiment, the novel method is used for a channel width shading of a PMOS transistor cell.

    Abstract: A memory device includes memory cells each having a capacitor including a lower electrode, a ferroelectric film and an upper electrode which are formed in this order over a substrate made of silicon. The ferroelectric film is selectively grown on the lower electrode. Such selective formation of the ferroelectric film on the lower electrode having a desired shape prevents a damaged portion from occurring in the ferroelectric film, thus making it possible to downsize the memory cells.

  • Publication number: 20040065914
    Abstract: Since at least a portion of a trench capacitor electrode is formed by a metal, the electrical sheet resistance of the electrode can be lowered, and the signal propagation time prolonged by CR delay can be shortened. This can reduce the read/write time. The formation of a buried gate electrode can realize a reduction of the cell area, which is required in a DRAM- and a DRAM/logic-embedded device. This can increase the gate length and reduce the short channel effect. Since an insulating protective film is deposited on the gate electrode, a bit line contact can be formed in self-alignment.
