摘要:
Provided is an annealing apparatus, which is free from a problem of reduced light energy efficiency resulted by the reduction of light emission amount due to a heat generation and capable of maintaining stable performance. The apparatus includes: a processing chamber 1 for accommodating a wafer W; heating sources 17a and 17b including LEDs 33 and facing the surface of the wafer W to irradiate light on the wafer W; light-transmitting members 18a and 18b arranged in alignment with the heating sources 17a and 17b to transmit the light emitted from the LEDs 33; cooling members 4a and 4b supporting the light-transmitting members 18a and 18b at opposite side to the processing chamber 1 to make direct contact with the heating sources 17a and 17b and made of a material of high thermal conductivity; and a cooling mechanism for cooling the cooling members 4a and 4b with a coolant.

An automatic control system controls a controlled variable serving as an object 2 to be controlled so that the object 2 approaches a predetermined target value, by means of an optimum regulator 4. The automatic control system include: a gain setting section 48 for setting a gain; a comparing section 48 for comparing the target value with the controlled variable serving as the object; and a weight control section 50 for weighting the gain set by the gain setting section so as to increase the weight from 0 to 1 within a predetermined period of time and for deriving a corrected manipulated variable in response to the time when a difference between the target value and the controlled variable comes within a range of a predetermined percentage of the target value, so that the corrected manipulated variable is added to the manipulated variable derived by the optimum regulator. Thus, the gain is controlled so as to gradually increase only within a restricted range, so that it is possible to quickly and accurately control an object.

This invention relates to a thermal processing method including: a placing step of placing an object to be processed onto a stage arranged in a processing container that can be vacuumed; and a heating step of heating the object to be processed to a predetermined temperature. The object to be processed is heated under a state in which a temperature distribution is maintained in such a manner that a temperature at a central portion of the object to be processed is high while a temperature at a peripheral portion of the object to be processed is low, during at least a part of the heating step.

The invention relates to a phase shift photomask in which the peripheral region portion of a phase shift layer is removed by a relatively simple procedure and which has no or little defect and is inexpensive, a blank therefor, and a process for fabricating them. The process includes the steps of forming phase shift layer 23 all over the surface of one side of transparent substrate 21, and immersing only the peripheral region of substrate 21 in etching solution 25 to etch away the peripheral region of phase shift layer 23, whereby phase shift layer 27 is confined within an area smaller than that of substrate 21.
