Disclosed is a substrate processing apparatus including a processing vessel in which a target substrate W is processed by using a high-pressure fluid in a supercritical state or a subcritical state, and pipes that are divided into a first pipe member and a second pipe member in a flowing direction of the fluid and circulate the fluid are connected to processing vessel. A connecting/disconnecting mechanism moves at least one of first and second pipe members between a connection position and a separation position of first pipe member and the second pipe member, and opening/closing valves are installed in each of first and second pipe members and are closed at the time of separating pipe members.

Disclosed is a fluid heating apparatus including a halogen lamp 23, and a tubular structure 26 surrounding the heating lamp and having a fluid inlet 24 and a fluid outlet 25. The tubular structure 26 comprises plural straight pipes 26a arrayed circumferentially around the halogen lamp 26, with adjacent straight pipes 26a being in contact with each other, or being slightly spaced from each other. At least the surfaces, facing the halogen lamp 26, of the straight pipes 26a are coated with a black paint 27, or a radiant-light-absorbing paint.

A vapor drying apparatus comprises a processing chamber 1a adapted to contain semiconductor wafers W; a supply nozzle 2 adapted to supply IPA vapor or N2 gas into the processing chamber 1a; a two-fluid nozzle 3 connected to both of an IPA supply source 8 and an N2 gas supply source 5 and adapted to produce a mixed fluid of IPA and N2 gas; a vapor generating apparatus 10 adapted to produce IPA vapor by heating the mixed fluid produced by the two-fluid nozzle 3; an N2 gas supply line 23 connected to the upstream side of the two-fluid nozzle 3; and a mixed fluid supply line 22 connected to the downstream side of the two-fluid nozzle 3. An open-and-close valve V2 is provided on a branch line 25 connecting the N2 gas supply line 23 and the mixed fluid supply line 22. First, N2 gas is supplied to the two-fluid nozzle 3 while IPA from the IPA supply source 8 is supplied to the two-fluid nozzle 3 so as to produce the mixed fluid, followed by supplying it to the processing chamber 1a so as to perform a first drying step. Subsequently, N2 gas from the N2 gas supply source 5 is supplied to the processing chamber 1a through the two-fluid nozzle 3 and the branch line 25 so as to perform a second drying step.

Disclosed are an evaporator, an evaporation method, and a substrate processing apparatus, which can increase the concentration of generated vapor of an organic solvent and efficiently heat the organic solvent. The evaporator includes a fluid tube, a liquid organic solvent supply device for supplying the organic solvent liquid to one end of the fluid tube, and heating units for heating the fluid tube. The fluid tube has a cross section that increases from the one end to the other end. When the organic solvent liquid supplied to one end of the fluid tube is heated, the organic solvent vapor is discharged from the other end of the fluid tube. The substrate processing apparatus includes the above-described evaporator.

Provided is a method of producing a composite metal oxide including, to calcine a composition containing an alkali metal and obtain a composite metal oxide, calcining the composition while being arranged on a mount a part of which in contact with the composition is formed of a metal oxide component. The metal oxide component has a content of K atoms ranging from 5 to 13 parts by weight in terms of K2O with respect to 100 parts by weight of the metal oxide component, and a total content of Al atoms, Zr atoms, Mg atoms, and Ce atoms ranging from 15 to 70 parts by weight in terms of oxides with respect to 100 parts by weight of the metal oxide component. The present invention thus provides a method of producing a composite metal oxide containing an alkali metal with reduced production costs.
摘要:
A substrate processing method which can reduce the number of particles to be left on each substrate is provided. In the substrate processing method, substrates W to be processed are dried, by using a fluid heated by a heating apparatus having one or more heating mechanisms. The substrate processing method comprises a first step of supplying a mixed fluid containing a gas and a processing liquid and heated by the heating apparatus, into a processing chamber in which the substrates to be processed are placed, and a second step of supplying the heated gas into the processing chamber. The output of at least one of the heating mechanisms is kept at a preset constant value for a period of time during which a predetermined time passes after the start of the first step. In the second step, the output of the heating mechanism is determined under a feed back control.
