摘要:
A cluster tool module for dry process cleaning of substrates. A substrate process reactor body assembly includes a gas inlet and gas outlet on opposing sides of a ceramic reactor body. A linear xenon flash lamp in a light bar provides a UV source for uniform distribution over a substrate by use of a light filter. Infrared heating is also provided by a plurality of infrared lamps in the light box. A moisturizer is provided for safe introduction of water vapor into the gas flow.
摘要:
Megasonic cleaning system for use in cleaning of electronic or other items such as semiconductor wafers or semiconductor substrates in a wafer carrier. Formed piezoelectric transducers are bonded to a tubular envelope at a low temperature and are excited at a first frequency or a second higher frequency for cleaning of items in a cleaning tank. A novel sealing assembly accommodates tubular envelopes of varying diameters.
摘要:
A chemical processing system for generating ultra-pure chemicals near the site of use. The system includes in series a supply of chemical or the site of use which may be a tank or drum and may be a point of use for semiconductor manufacturing, a concentrate sensor, a pump, a filter, a reactor vessel, and an optional heat exchanger, all connected by Kel-F tubing. Sources of pure filtered gas connect to the reactor vessel. An ozone generator can likewise connect to the reactor vessel. An optional isolation coil can likewise connect between the gas source and the reactor vessel.
摘要:
A process for etching oxide films on the semiconductor, or other substrates, in a sealed photochemical reactor. Anhydrous hydrogen fluoride (AHF) gas, or other halogen containing gases, and alcohol vapor carried by an inert gas, such as nitrogen, are passed over the oxides to be etched. The UV radiation shines through a window, which passes the UV radiation onto the oxides while the gases are flowing, and enhances and controls etching of the oxides. The UV window is impervious to the etch process gases. The etch rates are modified, providing for improved oxide etching characteristics.
摘要:
Method and apparatus for uniform direct radiant heating in a rapid thermal processing reactor where uniformity of temperature across the width and breadth of a semiconductor wafer is achieved by placement of a dome-shaped thermal insert in close proximity to a semiconductor wafer in process. Thermal energy is absorbed by the thermal insert from the semiconductor wafer at a high rate where the spacing between the thermal insert and semiconductor wafer is at a minimum and at a gradually reduced rate where the spacing between the thermal insert and semiconductor wafer is gradually increased. A guard ring is also incorporated to negate bottom side reflective thermal energy exposure.

A single substrate high frequency sonic processing module uses a substrate chamber dimensionally sized to the substrate for immersing the substrate in processing solution. Sonic wave permeable membranes form two ends of the substrate chamber along a sonic wave path therethrough. A sonic wave generated by a transducer external to the substrate chamber, travels through sonic wave conducting liquid in contact with the first membrane, external to the substrate chamber. The liquid is shaped by a sonic wave guide of continuously diminishing cross sectional area along the sonic wave path therethrough, thus intensifying and concentrating the sonic wave entering the substrate chamber. The sonic wave passes through the second membrane to a sonic absorbing and dissipating ante chamber. A method for sonic processing of substrates is disclosed. The individual sonic processing modules are combined into a single system for simultaneously processing plural substrates. The minimal sized substrate chamber provides effective processing with minimal processing solution, minimizing cost and disposal. The shaped wave guide concentrates and intensifies the sonic wave guide to provide enhanced processing.
摘要:
A cover for a fluid processing chamber is formed of a resilient, heat and chemical resistant laminate of at least three layers. The first layer is a Teflon sheath, the second layer is a blanket heater, and the third layer is a plurality of thin sheets of silicone rubber. The laminate is formed by vacuum formation of the Teflon sheath onto the blanket heater which is supported by the silicone rubber. The opening to the chamber is formed with a rigid lip. The laminate is contained in a stainless steel housing which has an opening therein sized to encompass the perimeter of the chamber lip. Pressure on the cover housing achieves a fluid tight seal with the chamber. No fluid seeps between the cover and the lip even when processing requiring vigorous fluid agitation is carried out in the sealed chamber.

This method enables the use of nanowire or nano-textured forms of Polyaniline and other conductive polymers in energy storage components. The delicate nature of these very high surface area materials are preserved during the continuous electrochemical synthesis, drying, solvent application and physical assembly. The invention also relates to a negative electrode that is comprised of etched, lithiated aluminum that is safer and lighter weight than conventional carbon based lithium-ion negative electrodes. The invention provides for improved methods for making negative and positive electrodes and for energy storage devices containing them. The invention provides sufficient stability in organic solvent and electrolyte solutions, where the prior art processes commonly fail. The invention further provides stability during repetitive charge and discharge. The invention also provides for novel microstructure protecting support membranes to be used in an energy storage device.
