Abstract: A method for optimizing the illumination conditions of a lithographic apparatus by computer simulation using full resist calculation, the lithographic apparatus comprising an illuminator, a projection system, and a mask having a pattern to be printed in a layer of photoresist material formed on a substrate. This method includes defining a lithographic problem, which may include a lithographic pattern to be printed on a wafer; choosing a resist model of a resist process to be used to print a pattern in the layer of photoresist material; selecting a grid of source points in a pupil plane of the illuminator; calculating separate responses for individual source points, each of the responses representing a result of a single or series of simulations using the resist model; and adjusting an illumination arrangement based on analysis of accumulated results of the separate calculations.

This method includes defining a lithographic pattern to be printed on the substrate, selecting a simulation model, selecting a grid of source points in a pupil plane of the illuminator, calculating separate responses for individual source points, each of the responses representing a result of a single or series of simulations using the simulation model, calculating a metric representing variation of the separate responses for individual source points with defocus and adjusting an illumination arrangement based on analysis of the metric.

Abstract: The monitoring device incorporates transducing devices for converting the desired measured parameters into electrical signals capable of being processed by a local computer or microprocessor system. The device receives a set of customized questions for presentation to an ambulatory patient. The device interacts with the ambulatory patient and then, via a modem or other electronic communication device, transmits the measured parameters and answers to the customized questions to a computer located at a remote site. At the remote location, the various indicia of the ambulatory patient's condition are monitored and analyzed by the medical professional caregiver. To provide the ambulatory patient with an added level of convenience and ease of use, such monitoring device is contained in a single integrated package.

Abstract: A dynamic reimageable document or electric paper can be formed from ordinary substrates such as paper, transparencies or fabric by printing of microencapsulated Gyricon beads onto one or more discrete surface areas of the substrate. The substrate can include both fixed print regions formed by conventional fixed ink processes and dynamic reimageable regions formed by the Gyricon beads. The Gyricon beads are preferably bichromal and of contrasting colors, such as black/white so as to be changeable to display two states by selective application of electromagnetic force to the beads. By providing bichromal beads in differing color combinations, such as red/white and black/white, a multi-colored document can be achieved in which various fields of the document, representing text, images or graphics, may be in differing colors. Moreover, operations to perform both imaging or erasure can act on the discrete reimageable regions so that the versatility of the electric paper can be enhanced.

Abstract: The present invention provides a method for drilling, analyzing, and stabilizing subsurface formations. The system is generally formed around a reusable bottomhole assembly (BHA) that provides an anchoring and thrust mechanism, furnishing the necessary downward force needed to provide comminution of geological material in a borehole. The BHA is conveyed into the borehole via a communications link wireline equiped with internal power and data telemetry lines. The BHA permits the use of multiple comminution sampling and analysis tools via a coupling device. The BHA and communications link wireline are mounted so as to couple with different tools. The main drilling mechanism is a torque drive assembly powered coring tool. A borehole televiewer and/or logging analysis tool may follow each coring period. The final step in each coring period is a wellbore consolidation technique. This series of steps is then repeated, each time coring the wellbore to a deeper depth.

Abstract: A creep testing fixture and method for applying a precise amount of constant tensile stress to a creep test specimen to allow for precise measurement of creep in the test specimen. The fixture includes first and second mounting grips for holding opposite ends of a test specimen. A frame supports the mounting grips for relative reciprocal movement toward and away from each other. A tensile spring is connected between the first and second mounting grips. The frame subjects a test specimen held between the mounting grips to tensile stress in response to axially inward force that the tensile spring applies to the frame.

Abstract: Apparatus (10) is shown for providing a flow of humidified air at a selected humidity level, and a method is disclosed of monitoring olfactory parameters of a sample gas or vapor to provide a “finger print” or profile of an odor. The flow of humidified air is used to set a level of humidity in a sensor chamber (36) which is the same as the level of humidity in a sample chamber (44) containing the sample of gas or vapor. The sample gas or vapor is then introduced into the sensor chamber (36), where an array of olfactory sensors record the odor profile, without a sudden change of humidity level when the sample gas or vapor is admitted. The flow of humidified air at a selected humidity level is obtained from a generator (10) having a controllable valve 14 for directing a clean dry air stream along either of two paths (17, 18), one of which includes a humidifier 22.

Abstract: A method is described for fabricating a cloisonné structure, in which a top surface of a metal oxide layer is made coplanar with a top surface of a metallic structure formed on a substrate. A nitride layer is deposited on at least the top surface of the metallic structure, and the metal oxide layer is deposited over the metallic structure and the nitride layer. The metal oxide layer is then polished by a chemical-mechanical polishing (CMP) process using a slurry, to expose the nitride layer on the top surface of the metallic structure. Polishing of the nitride layer causes ammonia to be generated in the slurry. The ammonia is extracted as a gas from the slurry, and a signal is generated in accordance with the ammonia concentration. The CMP process is terminated in accordance with a change in the signal. In a preferred embodiment, the metal oxide is aluminum oxide, the nitride is aluminum nitride, and the nitride layer is deposited as a conformal layer on the substrate and the metallic structure.
