  • Patent number: 7169283
    Abstract: In an anodization apparatus and an anodization method for electrochemically treating a target substrate by irradiating the target substrate with light, treatment of a large target substrate can be made possible with smaller constituent elements. The electrical contact with the target substrate by a contact member is realized by a plurality of contact members or by the movement of a contact member to change the electrical contact position. The target substrate is manufactured in advance so as to have such a structure that portions thereof to be in contact with the plural contact members are connected to portions of a conductive layer on a treatment part thereof respectively.

  • Patent number: 7118663
    Abstract: An anodic oxidation apparatus and an anodic oxidation method are provided that enable uniform photoirradiation of a treatment part of a target substrate, thereby realizing enhancement in uniformity of anodic oxidation in the surface of the target substrate. The anodic oxidation apparatus includes: a lamp that emits light; a target substrate holder provided at a position reached by the emitted light and capable of holding the target substrate; a cathode electrode that is provided on the way of the emitted light to reach the target substrate and that has an opening portion to allow light to pass therethrough and has a conductor section not transmitting light; and a vibrating mechanism to periodically vibrate a spatial position of one of the cathode electrode, the lamp, and the target substrate holder.

  • Patent number: 6121579
    Abstract: A heat treating apparatus comprises a process chamber within which a wafer is subjected to a heat treatment. A supporting plate for supporting the wafer is arranged within the process chamber. A process gas is supplied from above into the process chamber. A main heating means for heating the wafer is arranged below the process chamber, with a transmitting window interposed therebetween. The main heating means includes a plurality of heating sources for irradiating the supporting plate with heat rays so as to heat the wafer indirectly and a rotatable table having the heating sources arranged on the front surface thereof. The heat treating apparatus also comprises an auxiliary heating means for compensating for an uneven temperature caused on the surface of the wafer by the main heating means.

  • Patent number: 6111225
    Abstract: A thermal processing apparatus for a semi-conductor wafer. A holder is provided within a processing vessel on which the wafer to be processed is placed. Upper and lower heaters are provided above and below the holder in order to heat the wafer. Each of the heaters are attached within heating vessels. A gas supply head supplies a processing gas in a shower form between the upper heater and the holder. The uniformity of the surface temperature of the wafer is improved by heating the wafer from both above and below.

  • Patent number: 5938850
    Abstract: A single wafer heat treatment apparatus in which an object to be treated placed on a susceptor supported on a heat insulating member is heat-treated by indirectly heating the object to be treated by means of heating lamps disposed under the susceptor, characterized in that a gas entry preventive member for preventing process gas from being turned about the back surface of the susceptor is provided on a peripheral edge portion of the back surface of the susceptor. With this, process gas having entered the back surface of the susceptor is consumed by the adherence of a formed film to the surface of the gas entry preventive member.

  • Patent number: 5352902
    Abstract: In conducting a plurality of kinds of surface-treatments on objects to be treated, concentration of produced gases in exhaust gas discharged from a reaction vessel are detected, and data of the detected concentrations are compared with reference data stored in a control unit to continuously control and process the respective surface-treatments. As a result, processing control can be performed suitably for the respective kinds of surface-treatments, and different kinds of surface-treatments can be continuously conducted by one and the same surface-treatment device.

  • Patent number: 4954684
    Abstract: A vertical type heat-treating apparatus has a process tube, disposed upright along the lengthwise direction, for receiving a target object to heat-treat it under a predetermined condition, and a heater, provided around the process tube, for heating the target object in the process tube. After heat treatment is executed with the heater disposed around the process tube, the heater is moved upward by an elevator away from the process tube for cooling down the inside of the process tube.
