Abstract: The present invention provides a method for tiling an integrated circuit having a critically matched device such as a transistor. The method obtains an advantage of automatically improving metallic density over critically matched devices thus yielding improved CMP. The method may include the steps of: identifying critically matched devices in the integrated circuit; placing metal tiles over the critically matched device; performing a density test around each critically matched device; and if a density test is not satisfied around a critically matched device, placing at least one metal strip over a critically matched device.

Abstract: A method for placing tiles in an integrated circuit has matched devices that includes the steps of (1) calculating a metal spacing for tiles to be placed adjacent to the matched device in the integrated circuit; (2) calculating a lateral spacing for tiles to be placed adjacent to the matched device in the integrated circuit; (3) placing tiles about the matched device based on the metal spacing and the lateral spacing; (4) performing a density test in an area around the matched device; and (5) if a density test is not satisfied in the area around the matched device, dividing the matched device into at least two subdevices and repeating, with respect to each subdevice, the steps of calculating a metal spacing, calculating a lateral spacing, and placing tiles about each subdevice. The method is further adaptable to various kinds of matched devices including poly resistors, diffused resistors, double-poly capacitors, metal-insulator-metal capacitors, and fringe capacitors.

Abstract: In accord with one aspect of the invention, an apparatus for illuminating and magnifying an object in a sterile field for observation is provided. A holder is mounted at one end of a base assembly. A magnifying lens is mounted to the holder and defines a field of vision.

Abstract: A multiplier (10) includes a transconductor (14) and a multiplier core (34). The transconductor (14) converts an RF voltage signal to an RF current signal. The RF current signal modulates the quiescent currents flowing in current conducting elements (23, 24), thereby generating a modulated current signal. The modulated current signal is transmitted to the multiplier core (34), where it is combined with an LO signal to generate an output signal. The transconductor (14) and the multiplier core (34) have their current conduction paths separated from each other by the current conducting elements (23, 24).

Abstract: A circuit for generating a plurality of timing signals includes a plurality of cascade-connected delay cells, each having an input coupled to an output of another, and a plurality of latches. Set inputs of various latches are coupled to outputs of various delay cells to determine times of occurrence of leading edges of various timing pulses. Reset inputs of the various latches are coupled to outputs of various delay cells to determine times of occurrence of trailing edges of various timing pulses. The circuit includes a phase detector having a first input coupled to receive a clock signal and a second input coupled to an output of one of the delay cells to receive a signal indicative of propagation of a logic state through a first group of the delay cells, to produce an adjustment signal indicative of whether the phase of the indicator signal is ahead of or behind the phase of the clock signal.

Abstract: A method and an improved eductor apparatus for producing ultrafine explosive particles is disclosed. The explosive particles, which when incorporated into a binder system, have the ability to propagate in thin sheets, and have very low impact sensitivity and very high propagation sensitivity. A stream of a solution of the explosive dissolved in a solvent is thoroughly mixed with a stream of an inert nonsolvent by obtaining nonlaminar flow of the streams by applying pressure against the flow of the nonsolvent stream, to thereby diverge the stream as it contacts the explosive solution, and violently agitating the combined stream to rapidly precipitate the explosive particles from the solution in the form of generally spheroidal, ultrafine particles. The two streams are injected coaxially through continuous, concentric orifices of a nozzle into a mixing chamber. Preferably, the nonsolvent stream is injected centrally of the explosive solution stream.

Abstract: High speed conversion of an analog input signal to a digital output signal is performed by applying the analog input to an input of a unity gain amplifier. During a first pass, an output signal produced by the amplifier is applied to inputs of each of a plurality of comparators. A first group of successively larger reference voltages are applied to reference inputs of the comparators, respectively. A plurality of the comparators switch in response thereto to produce output signals indicative of a range within which the output of the amplifier lies. The outputs of the comparators are encoded to effectuate conversion thereof to an analog representation of the amplifier output. The analog representation is compared to the analog input signal and the difference therebetween is applied to the input of the amplifier. During another pass another group of reference voltages, each substantially lower than corresponding values thereof during the previous pass, are applied to the reference inputs of the comparators.

Abstract: A smoking and baking apparatus which is characterized by a cabinet having an outer shell and an inner shell that define a smoke channel therebetween. A firebox is located in the bottom of the cabinet and a pair of spaced flanges are positioned over the firebox for receiving a removable water pan. One or more doors close the cooking chamber of the cabinet, which cooking chamber is located above the firebox and is defined by the inner shell. A separate door closes the firebox and the water pan separates the firebox from the cooking chamber. A vertical duct or chimney is provided in the cabinet channel, which chimney opens to the smoking chamber at the lower end of the inner shell above the water pan and to the atmosphere at the upper end of the outer shell. When the water pan is resting on the spaced flanges over the firebox beneath the cooking chamber, smoke generated in the firebox is diverted by the water pan upwardly into the channel formed by the outer shell and the inner shell.

Abstract: A voltage offset introduced in a differential amplifier stage by the addition of an offset current is rendered relatively constant by making the offset current a function of, and responsive to, the level of the differential input voltage applied to the differential amplifier stage.

Abstract: A carrier for supporting a primer explosive charge in operative relationship to initiating means therefor comprises a cup having a recessed portion in its closed bottom end for engaging an explosive-containing plastic connecting block, used to explosively couple a low-energy detonating cord (LEDC), threaded through a tunnel in the cup, to a percussion-actuated detonator seated in a cavity (cap well) in the cup. A number of such primers can be made to slide on a single LEDC downline for placement in decked explosive charges in a borehole. Two tubular members project into the cup from the recessed portion, forming one or two cord-threading tunnels and a cap well. Besides initiation of a detonator by an LEDC downline via the explosive coupler, the carrier allows the primer charge to be initiated by a high-energy detonating cord or an electric detonator in an axial tunnel in the cup, or by a length of LEDC threaded through a tunnel and connected to a non-electric detonator seated in the cap well.
