摘要： Windshear detector using Rayleigh-backscattered light and a molecular filter for optical discrimination, and frequency locking of a laser, to detect windshear. The windshear detector has a pulsed ring laser that transmits a signal out of the detector and receives reflected backscatter of the transmitted signal. The ring laser is driven with an injection laser. Both lasers are ultimately keyed to the molecular transmission or absorption filter with locking electronics. The received reflected backscatter is detected and processed into a signal that indicates whether there is windshear or turbulence.

摘要： A method of removing materials, and preferably photoresist, from a substrate comprises dispensing a liquid sulfuric acid composition comprising sulfuric acid and/or its desiccating species and precursors and having a water/sulfuric acid molar ratio of no greater than 5:1 onto an material coated substrate in an amount effective to substantially uniformly coat the material coated substrate. The substrate is preferably heated to a temperature of at least about 90° C., either before, during or after dispensing of the liquid sulfuric acid composition. After the substrate is at a temperature of at least about 90° C., the liquid sulfuric acid composition is exposed to water vapor in an amount effective to increase the temperature of the liquid sulfuric acid composition above the temperature of the liquid sulfuric acid composition prior to exposure to the water vapor. The substrate is then preferably rinsed to remove the material.

摘要： An apparatus having a processing chamber for processing a semiconductor wafer under evacuated conditions that is capable of transfer of the wafer from the processing chamber under conditions that are substantially equal to the pressure of an adjacent environment. In a preferred embodiment, the processing chamber is pressurized and vented with a source of high purity dry gas that is diffused into the chamber through a diffuser to pressurize the processing chamber after processing of the wafer is completed. A chamber equalization port between the processing chamber and the adjacent environment is opened to maintain the pressure within the chamber at or slightly above the pressure of the adjacent environment, and the chamber valve is then opened. The wafer can then be removed from the processing chamber, and a new wafer can be inserted. The chamber is then sealed by closing the chamber valve and the equalization port, and the atmosphere within the processing chamber is evacuated to a desired level. The new wafer is then processed, and the above steps are repeated to remove the wafer once processing has finished.

摘要： An aerosol cleaning apparatus and a method of treating a substrate within such an apparatus prevent contaminant recirculation by controlling the post-impingement exhaust flow through control of the aerodynamic behavior of the contaminant laden exhaust stream. By the present invention, the post-impingement exhaust flow is divided into two streams. A first stream is the main stream flowing initially over the contaminated side of the wafer and carrying most of the suspended contaminants into the exhaust. The second stream flows initially over the cleaned side of the wafer and eventually into the exhaust stream. A flow separator is provided for dividing the post-impingement aerosol spray into plural flow streams. Additionally, the aerosol chamber can advantageously include a shroud positioned within the aerosol chamber just to the side of the nozzle but further away from the exhaust than the nozzle for restricting flow from the second post-impingement stream around the nozzle and into the first post-impingement stream. In accordance with a preferred embodiment, the apparatus is designed for cleaning the surface of a semiconductor wafer by impinging the surface with a cryogenic aerosol spray.

摘要： A process for etching high dielectric constant (high-k) films (e.g., ZrzSiyOx, HfzSiyOx, ZrzHfyOx, HfzAlyOx, and ZrzAlyOx) more rapidly than coexisting SiO2, polysilicon, silicon and/or other films is disclosed. The process comprises contacting the films with an aqueous solution comprising a fluoride containing species at a concentration sufficiently dilute to achieve a desired selective etch of the high-k film. The etching solution is preferably used above ambient temperature to further increase the etch selectivity of the high-k films relative to coexisting SiO2 and/or other films. The etch rate of the solution can also be adjusted by controlling the pH of the etching solution, e.g., by the addition of other acids or bases to the solution (for example, HCl or NH4OH).

摘要： A position sensor is provided which incorporates the first and second magnetic members which are attached to an object whose position is to be determined. First and second magnetic sensors are disposed at positions in association with the two magnetic members. As the object moves along a predetermined path, the first and second magnetic members dispose a predetermined amount of magnetic material in the zones of the two sensors. By measuring the changing impedance of the winding of one of the sensors and comparing that value to the impedance of the winding of the other sensor, corrections can be made to determine the position of the object notwithstanding the fact that external effects may have changed the conditions under which the measurements are being taken. For example, gaps between the magnetic members and the sensors can possibly change from one time to another or the ambient temperature surrounding the sensors and the magnetic members could have changed. By comparing the values of the two sensor readings, these variabilities can be factored out of the determination and the accurate position of the object can be measured.
