摘要:
A thermal processing unit of the present invention includes: a holder that holds a plurality of substrates; a reaction container into which the holder is conveyed; a process-gas supplying mechanism that supplies a process gas into the reaction container; and a heating mechanism that heats the reaction container to conduct a film-forming process to the substrates when the process gas is supplied. Flow-rate-parameter table-data associating number-data of the substrates to be processed by one batch-process with target-data of flow-rate parameter of the process gas is stored in a flow-rate-parameter table-data storing part. A controlling unit obtains target-data of flow-rate parameter of the process gas, depending on an actual number of the substrates to be processed by one batch-process, based on the flow-rate-parameter table-data stored in the flow-rate-parameter table-data storing part, and controls the process-gas supplying mechanism according to the obtained target-data. The target-data of flow-rate parameter are determined in such a manner that a speed of the film-forming process is uniform among a plurality of batch-processes in which the numbers of substrates to be processed are different from each other.

This invention is a method of determining set temperature trajectories for a heat treatment system that conducts a first heat treatment process and a second heat treatment process to an object to be processed. The method comprises the steps of: conducting the first heat treatment process to a first test object to be processed, by using a temporary first set temperature trajectory; measuring a result of the first heat treatment process produced on the first test object to be processed; and determining a first set temperature trajectory for the first heat treatment process by correcting the temporary first set temperature trajectory on the basis of the measured result of the first heat treatment process. The method also comprises the steps of: conducting the second heat treatment process to a second test object to be processed to which the first heat treatment process has been conducted by using the determined first set temperature trajectory, by using a temporary second set temperature trajectory; measuring a result of the first heat treatment process and the second heat treatment process produced on the second test object to be processed; and determining a second set temperature trajectory for the second heat treatment process by correcting the temporary second set temperature trajectory on the basis of the measured result of the first heat treatment process and the second heat treatment process.

The present invention provides a small-sized oscillator facilitating the adjustment of a resonance frequency, permitting mass productivity to be improved, sufficiently suppressing a fundamental wave, and permitting cost reduction, and provides radio equipment using the oscillator. In this oscillator, an oscillation circuit is formed by providing a line and a Gunn diode on a dielectric substrate. An NRD guide serving as an output transmission line is formed by disposing a dielectric strip between upper and lower conductor plates, and the above-mentioned line and the NRD guide are coupled. The cut-off frequency of this NRD guide is determined so that the fundamental wave component of an oscillation signal from the oscillation circuit is cut off, so that higher harmonic components are propagated.
