  • Patent number: 5399464
    Abstract: A stripping composition for removing positive organic photoresist from a substrate, such as a semiconductor wafer, contains a triamine, such as diethylene triamine, and a nonpolar or polar organic solvent, such as N-methyl pyrrolidone. This composition will remove positive photoresist from semiconductor wafers, even after ion implantation into the wafers through the positive photoresist. The wafers are immersed in the composition, for example, at a temperature of 110.degree. C. for five minutes, in an ultrasonic bath after heavy ion implantation doses through the photoresist, such as 1.times.10.sup.16 ions/cm.sup.2, for complete removal of the photoresist. Prebaking the photoresist at a temperature of between about 150.degree. and 220.degree. C. for a time of from about 15 minutes to about 30 minutes, prior to stripping the positive organic photoresist layer with the triamine, enhances the removal.

  • Patent number: 5393427
    Abstract: A process and installation for the removal of organic matter, phosphate ions and nitrogenous compounds from sewage wastewater. The installation comprises a raw sewage feed line 12 shown feeding into a primary separation basin 14. The primary separation basin 14 has an overflow flow line 16, discharging separated effluent to an attached growth fermentation vessel or fermenter 18. The fermenter 18 is filled with solid supports 20 with sufficient voids therebetween to allow the effluent to pass through the supports 20 and to allow for the growth of fermenting bacteria (not shown) on the supports 20. The supports 20 are shown diagrammatically in the drawings, and can be in the form of rotating discs, hanging or suspended ropes which move as the liquid is passed through the system, a fluidized bed in which the solids are kept in suspension by upward movement of the liquid, rings, slats or plates. The liquid effluent then passes out of the fermenter 18, through flow line 26, for further processing.

  • Patent number: 5393602
    Abstract: Polymeric materials having an inverse temperature transition, particularly bioelastic polymers comprising monomeric units selected from the group consisting of bioelastic pentapeptides, tetrapeptides, and nonapeptides, have been found to have controllable absorbent properties that can be varied with temperature or contact with liquids. The materials are selected to be in a contracted or swollen state initially, depending on the specific use. When the material is located under different conditions (such as a different temperature resulting from being either in contact with or at distance from human skin), the material undergoes swelling or contraction to switch to the other state.

  • Patent number: 5305221
    Abstract: This process models production integrated processing equipment, also known as cluster tools, modular equipment, track systems, etc. Further, the model produced by this invention is a real-world model, i.e., it is realistic and validatable. In addition, the invention provides a process for developing machine-specific implementations for PIPEs performing such complex processes as plasma etching, plasma deposition, chemical-vapor deposition, physical-vapor deposition, photolithography, photo-resist processing, rapid thermal processing, and oxidation, as well as other processes. The PIPE-specific model can be used for performance analysis. The effect of changes in process times, process recipes, and process mixtures on cycle time, throughput, resource utilization, and bottlenecks can be analyzed. These PIPE models may be used in the design or redesign of PIPEs. Further, the PIPE-specific model can be used to control material movement in the PIPE, including buffer dynamics to avoid machine lock-up.

  • Patent number: 5300779
    Abstract: Novel methods and devices are provided involving at least one chamber, at least one capillary, and at least one reagent involved in a system providing for a detectable signal. As appropriate, the devices provide for measuring a sample, mixing the sample with reagents, defining a flow path, and reading the result. Of particular interest is the use of combinations of specific binding pair members which result in agglutination information, where the resulting agglutination particles may provide for changes in flow rate, light patterns of a flowing medium, or light absorption or scattering. A fabrication technique particularly suited for forming internal chambers in plastic devices is also described along with various control devices for use with the basic device.
