Tokyo Electron Limited , or TEL, is a Japanese electronics and semiconductor company headquartered in Akasaka, Minato-ku, Tokyo, Japan.TEL is best known as a supplier of equipment to fabricate integrated circuits , flat panel displays , and photovoltaic cells . Tokyo Electron Device , or TED, is a subsidiary of TEL specializing in semiconductor devices, electronic components, and networking devices.As of 2011, TEL is the largest manufacturer of IC and FPD production equipment in Japan and the third largest in the world. The company was founded as Tokyo Electron Laboratories, Inc. in 1963.On September 24, 2013 Tokyo Electron and Applied Materials announced a merger. If approved by government regulators, the combined company, to be called Eteris, would be the world's largest supplier of semiconductor processing equipment, with a total market value of approximately $29 billion.

A processing apparatus includes a plurality of first gas supply channels configured to supply a plurality of gases to the process chamber, a second gas supply channel configured to supply a gas to the process chamber, the gas being used in processing the target substrate, a plurality of first valves configured to open and close the plurality of first gas supply channels, a second valve configured to open and close the second gas supply channel, and a controller. One of the plurality of first valves is a follow-up target valve. The controller controls opening/closing operation of the plurality of first valves such that opening durations of the plurality of first valves do not overlap with each other, and controls opening/closing operation of the second valve such that opening duration of the second valve has a predetermined time relationship with opening duration of the follow-up target valve.

A raw material gas supply apparatus is configured to obtain a difference between a set value and a measured value of a vaporized raw material, add the difference as a correction value to the set value of the flow rate of the carrier gas to maintain an amount of the vaporized raw material at the set value, and subtract a difference from a set value of a flow rate of the dilution gas to maintain a total flow rate of the carrier gas and the dilution gas at a constant level. The amount of the vaporized raw material is calculated by subtracting an integration value of a measured value of the flow rate of the inert gas in the supply period of the raw material gas from an integration value of the flow rate of the raw material gas which is measured in the supply period.

A peripheral exposure method for performing an exposure treatment by illuminating light to a periphery of a resist film formed on a substrate to be processed is discussed. The method includes rotating the substrate to be processed on a horizontal plane, bringing a coolant gas into contact with the periphery of the resist film of the substrate to be processed which is being rotated, and cooling the substrate to be processed. Further, the method also includes measuring a temperature of the substrate to be processed, wherein when the temperature of the substrate to be processed is equal to or less than a predetermined temperature, the exposure treatment is performed.
