摘要:
A fluid replacement apparatus for use with a portable body heating and cooling system is provided. The apparatus includes a frame with a support portion configured for supporting a reservoir of the portable body heating and cooling system. A heat exchange mechanism is retained in the frame. The heat exchange mechanism includes a thermostatically controlled receptacle for maintaining fluid circulating through the receptacle at a desired temperature. A cover member covers the reservoir to releasably couple the fluid replacement apparatus to the portable body heating and cooling system. The cover member includes a pump for circulating fluid between the heat exchange mechanism and the reservoir of the portable body heating and cooling system. Return and supply tubes extend between the cover member and the heat exchange mechanism. The supply tube is coupled to the pump land to a receptacle of the heat exchange mechanism for circulating fluid from the reservoir to the receptacle. The return tube is coupled to the receptacle and extends through the cover member for circulating fluid from the receptacle to the reservoir at the desired temperature, for maintaining the temperature of the fluid in the reservoir at the desired temperature.
摘要:
A vapor deposition system is provided which uses electromagnetic radiation for heating of a semiconductor wafer. The source of the electromagnetic radiation is typically a lamp having a color temperature corresponding to a wavelength in the range of 0.3 to 0.9 micrometers, and generally for a particular semiconductor to an energy greater than the energy required to cause transitions from the valence band to the conduction band of the semiconductor material used to construct the wafer and more preferably to a color temperature corresponding to an energy substantially at or above the energy required for direct (vertical) transitions from the valence band to the conduction band, thereby providing very high absorption of the incident radiation and very efficient direct heating of the wafer. No substrate is required for conducting heat to the wafer. The radiation is directed by a reflector through a window forming one side of the deposition chamber and impinges directly on the surface of the wafer. Although the window is typically chosen to be substantially transparent at the frequencies desired for heating the wafer, some absorption does occur, thereby heating the window as well. To maintain optimum control over the deposition process, the window is typically constructed with two spaced-apart plates and water is pumped therethrough to actively control window temperature.
