摘要:
The number of substrates held by a substrate holder is increased compared with conventional techniques while uniformity of a heat treatment is ensured. The substrate holder holds a plurality of substrates at predetermined vertical intervals. The substrate holder is carried into a heat treating furnace. A predetermined heat treatment is performed on the substrates. The substrate holder has two holder constituting bodies. Each of the holder constituting bodies has a plurality of columns and substrate holding sections. The columns are arranged on the circumference of the same imaginary circle. The substrate holding sections hold circumferential portions of the respective substrates. One of the holder constituting bodies holds the substrates under the condition that front surfaces of the substrates face upward, while the other of the holder constituting bodies holds the substrates under the condition that back surfaces of the substrates face upward. The substrate with the front surface facing upward and the substrate with the back surface facing upward are alternately arranged in a vertical direction. At least one of the holder constituting bodies moves in the vertical direction to change the positions of the holder constituting bodies relative to each other. A distance between one of a first pair of substrates that are vertically adjacent to each other and have the respective front surfaces facing each other and the other of the first pair of substrates is set to ensure uniformity of the treatment and larger than a distance between one of a second pair of substrates that are vertically adjacent to each other and have the respective back surfaces facing each other and the other of the second pair of substrates.
摘要:
A heat treatment method includes a substrate holder that holds a plurality of substrates at predetermined vertical intervals and is carried into a heat treating furnace for performing a predetermined heat treatment on the substrates. The substrate holder has two holder constituting bodies each having a plurality of columns and substrate holding sections. One of the holder constituting bodies holds the substrates at a first, vertically adjacent distance so that their front surfaces face each other, while the other of the holder constituting bodies holds the substrates at a second, vertically adjacent distance so that their back surfaces face each other wherein the second distance is smaller than the first distance to ensure uniformity of the heat treatment. At least one of the holder constituting bodies moves in the vertical direction to change the positions of the holder constituting bodies relative to each other.

A substrate holder has two holder constituting bodies, each having a plurality of columns arranged on an imaginary circle, and substrate holding sections that hold circumferential portions of respective substrates. The holder constituting bodies hold the substrates so that either their front surfaces or their back surfaces face upward with a substrate having an upward facing front and a substrate having an upward facing rear being alternately arranged in a vertical direction. At least one of the holder constituting bodies moves in the vertical direction to change the positions of the holder constituting bodies relative to each other.

摘要:
A film deposition apparatus is provided with a gas nozzle in which ejection holes that eject a reaction gas are formed along a longitudinal direction of the gas nozzle, and a flow regulation member that protrudes from the gas nozzle in either one of upstream and downstream directions of a rotation direction of a turntable. In such a configuration, a separation gas flowing from an upstream side of the rotation direction to the gas nozzle is restricted from flowing between the gas nozzle and the turntable on which a substrate is placed, and the reaction gas flowing upward from the turntable is restricted by the separation gas, thereby impeding a reaction gas concentration in a process area from being lowered.

A film deposition apparatus includes a first turntable including at least ten substrate receiving areas that receive corresponding 300 mm substrates; a first reaction gas supplying portion arranged in a first area inside the chamber to supply a first reaction gas; a second reaction gas supplying portion arranged in a second area away from the first reaction gas supplying portion along the rotation direction of the first turntable to supply a second reaction gas; and a separation area arranged between the first and the second areas. The separation area includes a separation gas supplying portion that supplies a separation gas that separates the first reaction and the second reaction gases, and a ceiling surface having a height so that a pressure in a space between the ceiling surface and the first turntable is higher with the separation gas than pressures in the first and the second areas.
摘要:
A memory other than a non-volatile memory in a numerical controller is divided into a plurality of memory areas in response to a command from a computer connected to the numerical controller. Whether a machining program has been stored in each of the divided memory areas is decided before a machining program stored on a hard disk in the computer is transferred to the memory other than the non-volatile memory. The machining program stored on the hard disk is then written to an area for which it is determined that no machining program is stored.

A film deposition device includes a chamber, a turntable, a first reactive gas supplying portion, a second reactive gas supplying portion, and a separation gas supplying portion. A convex part includes a ceiling surface to cover both sides of the separation gas supplying portion, form a first space between the ceiling surface and the turntable where a separation gas flows, and form a separation area between a first area and a second area, to maintain a pressure in the first space to be higher than pressures in the first area and the second area so that a first reactive gas and a second reactive gas are separated by the separation gas in the separation area. A block member is arranged to form a second space between the turntable and an internal surface of the chamber at an upstream part of the separation area along a rotation direction of the turntable.
摘要:
By coating the surface of a powder comprising a silicone resin and/or an organic powder with a specific hydrophilizing agent, such powder is hydrophilized. Such coated (treated) powder has extremely great dispersibility (ease of dispersion) and very good dispersion stability (long-term dispersion stability with lapse of time) in aqueous dispersion media, particularly under acidic and alkaline conditions, specifically at pH 3 through 13. Using the surface-treated powder, additionally, a dispersion with good dispersibility (ease of dispersion) and great dispersion stability, preferably for cosmetics can be provided. The use of the surface-treated powder, or the use of the dispersion can provide further a cosmetic excellent in dispersibility and dispersion stability and further in re-dispersibility and dispersion stability with lapse of time and smooth feeling as compared to the related art when selecting aqueous cosmetic as an agent form.
