Light is applied for preheating from a halogen lamp to a lower surface of a semiconductor wafer supported on a susceptor within a chamber. Thereafter, flash light is applied for flash heating from a flash lamp to an upper surface of the semiconductor wafer. Treatment gas supplied from a gas supply source is heated by a heater, and supplied into the chamber. A flow amount control valve is provided to increase a flow amount of the treatment gas supplied into the chamber. Contaminants discharged from a film of the semiconductor wafer during heat treatment are discharged to the outside of the chamber with a gas flow formed by a large amount of high-temperature treatment gas supplied into the chamber to reduce contamination inside the chamber.

A stage cleaning substrate for use in the operation of cleaning a substrate stage within an exposure unit compatible with immersion exposure and a dummy substrate for use during the adjustment of an exposure position of a pattern image are held in a cleaning substrate housing part and a dummy substrate housing part, respectively, provided in a substrate processing apparatus. For the operation of cleaning the substrate stage or an alignment operation within the exposure unit, the stage cleaning substrate or the dummy substrate is transported from the substrate processing apparatus to the exposure unit. The process of cleaning the stage cleaning substrate or the dummy substrate is performed in a cleaning processing unit of the substrate processing apparatus immediately before or immediately after the operation of cleaning the substrate stage or the alignment operation.

An inflatable resuscitation face mask comprising a top sheet joined to a bottom sheet to form an inflatable pocket which when inflated forms a raised body having an apex and a lower perimeter, wherein inflation means is provided on the mask and an opening at the apex allows air to be administered through the opening to an area underneath the inflated mask.

In an exposure unit compatible with immersion exposure, a dummy substrate to be used for an alignment process for adjustment of an exposure position for a pattern image is transferred to a substrate processing apparatus for performing a resist coating process before exposure and a development process after exposure. In the substrate processing apparatus, the received dummy substrate is reversed and transferred to a back surface cleaning unit, to be subjected to a back surface cleaning process. After that, the dummy substrate is reversed again and transferred to a front surface cleaning unit, to be subjected to a front surface cleaning process. The dummy substrate after being cleaned is transferred back from the substrate processing apparatus to the exposure unit. Since the alignment process can be performed by using a clean dummy substrate in the exposure unit, it is possible to reduce contamination of mechanisms in the exposure unit, such as a substrate stage and the like.
