Methods of forming electrically conductive and/or semiconductive features for use in integrated circuits are disclosed. Various pattern transfer and etching steps can be used, in combination with pitch-reduction techniques, to create densely-packed features. The features can have a reduced pitch in one direction and a wider pitch in another direction. Conventional photo-lithography steps can be used in combination with pitch-reduction techniques to form elongate, pitch-reduced features such as bit-line contacts, for example.

The information allows the users seeking to make contact to quickly take an action that is expected given the context of the first user as presenting the most relevant data allows the contacting users to take actions quickly and effectively.

Methods for removing silicon nitride and elemental silicon during contact preclean process involve converting these materials to materials that are more readily etched by fluoride-based etching methods, and subsequently removing the converted materials by a fluoride-based etch. Specifically, silicon nitride and elemental silicon may be treated with an oxidizing agent, e.g., with an oxygen-containing gas in a plasma, or with O₂ or O₃ in the absence of plasma to produce a material that is more rich in Si—O bonds and is more easily etched with a fluoride-based etch. Alternatively, silicon nitride or elemental silicon may be doped with a number of doping elements, e.g., hydrogen, to form materials which are more easily etched by fluoride based etches. The methods are particularly useful for pre-cleaning contact vias residing in a layer of silicon oxide based material because they minimize the unwanted increase of critical dimension of contact vias.

A computer based lottery which allows entries to be sold over the telephone, by ATM or POS machines, by email, or via kiosks, in which participants are invited to choose at least one unique number from a defined range of numbers, e.g. between one and one million which hopefully no-one else has or will select before the end of the competition. The participant can register their selection with an entry-logging engine (which can be an automated call answering system allowing the user to key in the number chosen by using the telephone keypad). This records the identity or contact details of the participant (for example telephone number or email address), the number selected by the participant, and the date and time of the entry, the entry-logging engine giving the participant an optional receipt number.

A fluid dispensing system provides a non-contact method of monitoring the change in the fluid volume over time. This approach avoids the use of probes or sensors that come into direct contact with the fluid to be dispensed. The system comprises an apparatus comprising three chambers. The first chamber has a fixed volume and contains a pressurized gas. A solenoid valve is used to control the flow of gas from the first chamber into the second. The second chamber is sealed so that the combined mass of air in the first and second chambers remains fixed. The third chamber is adjacent to the second and contains medication in the form of incompressible fluid that is to be administered to a human or animal subject via a suitable delivery port. A piston is disposed between the second and third chambers and is movable responsive to the flow of gas into the second chamber to dispense fluid from the third chamber as desired. By sensing the pressure in the first and second chambers at any point in time, a processor is programmed to calculate the flow rate or dispensed volume of the fluid being delivered using principles derived from the Ideal Gas Law.

The method includes forming a lower interlayer insulating layer on a semiconductor substrate, and forming a lower conductor pattern within the lower inter-insulating layer. A first insulating layer pattern which crosses a top surface of the lower conductor pattern is formed on the semiconductor substrate having the lower conductor pattern. A conductive spacer pattern electrically connected to the lower conductor pattern is formed on a sidewall of the first insulating layer pattern. A first interlayer insulating layer is formed on the semiconductor substrate having the conductive spacer pattern. The first interlayer insulating layer and the conductive spacer pattern are planarized to form a bottom electrode. A second insulating layer pattern which crosses a top surface of the bottom electrode and exposes a portion of the bottom electrode is formed on the semiconductor substrate having the bottom electrode. A phase change material spacer electrically connected to the bottom electrode is formed on a sidewall of the second insulating layer pattern. A second interlayer insulating layer is formed on the semiconductor substrate having the phase change material spacer. The second interlayer insulating layer and the phase change material spacer are planarized to form a phase change material pattern.

A method and apparatus is provided for high speed, non-contact method of measuring the 3-D coordinates of a dense grid of points on a surface, including high accuracy interpolation between grid points. A plurality of pulsed laser sub-projectors sequentially illuminates a plurality of discrete Gray code bar pattern transparencies carried on a spinning circular code disk to project high frame rate structured light. The structured light is reflected by the surface and recorded at high signal-to-noise ratio by a plurality of high frame rate digital cameras, then decoded and interpolated by electronic signal processing. A numerical formula is derived for numbers of equally spaced discrete code patterns on the code disk that allow each camera to receive pulses from all sub-projectors and all patterns at a constant frame rate. Methods to derive an extended complementary Gray code pattern sequence and to normalize measured signal amplitudes are presented.

Internet has brought in different means of communication that go beyond the boundaries of conventional interaction/communication methods. Therefore, it should now be possible to communicate with total strangers securely without having to worry about privacies. This invention thus relates to a method/system/framework enabling an online directory creation for the purpose of anonymous communication/interaction among total strangers seamlessly and securely using one or plurality of communication modes/media/mechanism without compromising the privacies of the communication parties involved and without them having to know the exact contact details of each other. Also, modern communication technologies enable any social entity to have a numerous forms of contacts. A conventional business card cannot hold this growing number of contact details. The online directory allows any user to maintain a very dynamic virtual business card that can allow an owner to include/exclude different contact details dynamically at his/her discretion depending on the type of recipient(s).

The invention relates to a method of high-temperature flue gas drying, which is particularly suitable for drying long flame coal, brown coal or other low rank coal. The coal-fired high-temperature flue gas is used to dry flammable and explosive coal types, such as brown coal in the direct contact method; therefore, the method has less gas exhaust, high thermal efficiency and high drying speed. The internal water content of the dried coal is obviously reduced, and the heating power of the dried coal is greatly increased. The invention also relates to the device using the method.

A non-contact method and apparatus for continuously monitoring a physiological event in a human or animal, such as blood pressure, which involves utilizing a laser-based interferometer system to produce a waveform that is representative of continuous blood pressure in a subject. The invention may preferably utilize a laser Doppler vibrometer which is oriented to produce a laser beam directed toward the subject substantially perpendicular to a skin surface of the subject wherein the skin surface is moveable in response to blood pressure. The vibrometer is sensitive to motion of the skin surface in a direction parallel to the laser beam and produces a signal representative of this motion. By plotting the velocity of the skin surface movement in the direction parallel to the laser beam with respect to time, a waveform is produced that has been found to be representative of the blood pressure waveform and highly defined to thereby permit accurate timing analysis thereof relating to cardiac cycles.
