摘要:
A thermal processing apparatus, performing processing accompanied with heating on a substrate, having an upper lamp group directed toward a prescribed direction and a lower lamp group perpendicularly intersecting with the upper lamp group is provided with a lower reflector between the upper and lower lamp groups. The lower reflector is so provided as to reflect light from lamps, included in the lower lamp group, present on both end regions in relation to the direction of arrangement. Thus, the thermal processing apparatus can efficiently irradiate an auxiliary ring with reflected light from the lower lamp group and improve temperature uniformity when heating the substrate.

A temperature measuring device for measuring the temperature of a wafer heated by light irradiation includes: a sheath thermocouple for detecting the temperature of a wafer to be measured by contacting the wafer to be measured; and a covering member for covering the surface of the sheath thermocouple. The surface of the covering member is flat in a predetermined region, and the part in the region can plane-contact the surface of the wafer. Thus, the temperature of the wafer can be measured accurately and in a stable manner, and the wafer surface is free from contamination with adhesives or the metal of the thermocouple.

A substrate processing apparatus and method includes, a plate that has a size equal to or larger than a principal face of the substrate, and has a horizontal and flat liquid holding face opposing the principal face of the substrate from below. A processing liquid supply unit supplies a processing liquid to the liquid holding face. A control unit controls the processing liquid supply unit and a movement unit to supply the processing liquid to the liquid holding face to form a processing liquid film, a contact step of bringing the principal face of the substrate and the liquid holding face close to each other to bring the principal face of the substrate into contact with the processing liquid film, and a liquid contact maintenance step of maintaining the processing liquid in contact with the principal face of the substrate.

In a thermal processing apparatus irradiating a substrate with light from a lamp for heating the substrate, an opening is formed in a reflector for mounting a camera unit. The camera unit images three portions of an auxiliary ring supporting the substrate, for obtaining the position of the center of the auxiliary ring before the thermal processing apparatus receives the substrate therein. The camera unit further images the substrate for obtaining the position of the center of the substrate before the thermal processing apparatus receives the substrate therein and places the same on the auxiliary ring. The thermal processing apparatus moves the substrate so that the center thereof coincides with the center of the auxiliary ring, and thereafter places the former on the latter. Thus, the auxiliary ring can be so designed as to reduce overlaps of the auxiliary ring and the outer edge of the substrate while the overlaps can be rendered uniform over the entire circumference of the substrate for improving temperature uniformity of the substrate.

In a thermal processing apparatus, using a lamp for heating a substrate, an opening is formed for a camera unit, which is used to image portions of an auxiliary ring supporting the substrate, to obtain the position of the center of the auxiliary ring. The camera further images the substrate to determine the center of the substrate before the thermal processing apparatus receives and places the substrate on the auxiliary ring. The thermal processing apparatus moves the substrate so that the center thereof coincides with the center of the auxiliary ring, and thereafter places the former on the latter. Thus, the auxiliary ring can be designed to reduce overlaps of the auxiliary ring and the outer edge of the substrate while overlaps can be uniform over the entire circumference of the substrate to improve temperature uniformity of the substrate.

A substrate heat treatment apparatus irradiating a substrate such as a semiconductor wafer with light and performing heat treatment is provided. 19 lamps 82 are arranged on a plane in the form of a honeycomb to form a lamp group 81. The lamp group 81 has 6-fold rotation symmetry about a symmetry axis XR. A substrate W is rotated about a rotation axis XW in a plane parallel to that formed by the lamp group 81. The symmetry axis XR of the lamp group 81 and the rotation axis XW of the substrate W are displaced for relaxing peaks and bottoms of illuminance distribution on the substrate W resulting from regularity of arrangement of the lamp group 81. Consequently, fluctuation of radial illuminance distribution on the substrate W is reduced and improving uniformity is improved. When the uniformity of radial illuminance distribution on the substrate W is improved, temperature uniformity of the substrate W in heat treatment can be ensured.
摘要:
A substrate temperature measuring apparatus includes a temperature signal generating device provided in contact with a substrate for generating a signal indicating its own temperature which follows the temperature of the substrate by thermal conduction, a device connected and responsive to the output of the temperature signal generating device for determining whether contact between the substrate and the temperature signal generating device is appropriate or not, and a device for carrying out a predetermined process according to a determination result of the determining device. It is possible to apply heat treatment to the substrate, to prevent the substrate from being subjected to heat treatment, or to give a necessary alarm according to the determination result. Since the next substrate is at room temperature when it first comes into contact with the temperature signal generating device after heat treatment, the temperature signal generating device lowers its temperature rapidly in such a manner that reflects a state of contact between the substrate and the temperature signal generating device. Based on change of the output of the temperature signal generating device at this time, it is possible to detect an undesired state of contact between the substrate and the temperature signal generating device, and to prevent inaccurate measurement of the temperature of the substrate.
