In the above-mentioned vacuum vapor deposition apparatus, the output range of the electron gun is changed, the electron beam irradiation position, the irradiation position of the electron beam are changed depending on the vapor deposition range of the vapor deposition film and the mixing ratio of the vaporization material in the alloy portion of the vapor deposition film. It was adjusted by changing the spread of steam by changing patterns such as time. However, in the film forming method of the vacuum vapor deposition apparatus which controls the electron beam as described above, the temperature of the evaporation material is changed by the change of the electron beam, the evaporation amount of the evaporation material is changed, and the spread of the vapor is changed. Without taking the step of changing the vapor deposition film, the vapor deposition range of the vapor deposition film and the mixing ratio of the evaporation material in the alloy portion of the vapor deposition film could not be adjusted.
Therefore, the response time from the change of the electron beam to the change of the vapor deposition film is long, and further, the spread of the vapor changes depending on the vapor density distribution of the evaporation material at that time, so it is left to the course of time at that time and the desired vapor deposition The film cannot be formed, and the controllable range of the deposited film is very narrow.

Next, the film forming method of the vacuum vapor deposition apparatus of the present invention will be described with reference to FIGS. FIG.
The positions of the crucibles 10 and 11 shown in FIG. FIG. 2 is a diagram when only the actuators 19 and 20 are operated to raise the vapor flow regulating plate 15 on the upstream side of the crucible 10 and the vapor flow regulating plate 16 on the downstream side of the crucible 11 to almost the same height. . As illustrated, when the vapor flow restricting plates 15 and 16 are raised, the spread of vapor on the upstream side of the evaporation material 12 under the substrate 1 and the spread of vapor on the downstream side of the evaporation material 13 can be narrowed instantaneously, It is possible to reduce the mixing ratio of the evaporation materials 12 and 13 (the portion indicated by the double-headed arrow in the figure). Therefore, the evaporation material 12,
The portion where 13 is deposited on the substrate 1 is thick, and the alloy portion where the mixed evaporation materials 12 and 13 are deposited on the substrate 1 can form a thin vapor deposition film. Further, since the spread of the vapor can be changed without intervening physical phenomena such as changes in the temperature and evaporation amount of the evaporation materials 12 and 13, the response time until the film thickness changes can be shortened. . In the state shown in the figure, even if the vapor flow regulating plate 14 on the downstream side of the crucible 10 and the vapor flow regulating plate 17 on the upstream side of the crucible 11 are moved up and down to adjust the spread of the vapor of the evaporation materials 12 and 13. Good.

Further, FIG. 3 shows actuators 19 and 20.
FIG. 6 is a diagram when only the steam flow restricting plate 15 on the upstream side of the crucible 10 and the steam flow restricting plate 16 on the downstream side of the crucible 11 are moved down to substantially the same height by operating only the steam generator. As illustrated, when the vapor flow restricting plates 15 and 16 are lowered, the spread of vapor on the upstream side of the evaporation material 12 under the substrate 1 and the spread of vapor on the downstream side of the evaporation material 13 can be instantaneously expanded. It is possible to increase the mixing ratio of the evaporation materials 12 and 13 (the portion indicated by the double-headed arrow in the figure). Therefore, the portion where the evaporation materials 12 and 13 are vapor-deposited on the substrate 1 is thin, and the alloy portion where the mixed evaporation materials 12 and 13 are vapor-deposited on the substrate 1 can be formed into a thick vapor deposition film. Also, the evaporation material 12, 13
Since the spread of the vapor can be changed without intervening physical phenomena such as the change in temperature and the amount of evaporation, the response time until the film thickness changes can be shortened. In the state shown in the figure, the vapor flow restricting plate 14 on the downstream side of the crucible 10 and the vapor flow restricting plate 17 on the upstream side of the crucible 11 are moved up or down to evaporate materials 12, 1
The spread of the steam of 3 may be adjusted.

It is a figure when only 1 is operated and the steam flow restricting plate 14 on the downstream side of the crucible 10 and the steam flow restricting plate 17 on the upstream side of the crucible 11 are raised to substantially the same height. As shown, when the vapor flow restricting plates 14 and 17 are raised, the substrate 1
The spread of the vapor on the downstream side of the lower vaporization material 12 and the spread of the vapor on the upstream side of the vaporization material 13 can be narrowed instantaneously, and the mixing ratio of the vaporization materials 12 and 13 remains unchanged. (The part indicated by the double-headed arrow) can be narrowed. Therefore, the evaporation materials 12 and 13 are
A thin vapor deposition film can be formed on the portion vapor-deposited on.
Further, since the spread of the vapor can be changed without intervening physical phenomena such as changes in the temperature and evaporation amount of the evaporation materials 12 and 13, the response time until the film thickness changes can be shortened. .

Further, in FIG. 5, only the actuator 21 is operated so that the vapor flow restricting plate 17 on the upstream side of the crucible 11 is operated.
It is a figure when only one is lowered. As illustrated, when the vapor flow restricting plate 17 is lowered, the spread of the vapor on the upstream side of the evaporation material 13 can be instantly widened, and the evaporation material 1
It is possible to widen only the spread of the vapor of the evaporation material 13 (the portion indicated by the double-headed arrow in the figure) while keeping the mixing ratio of 2 and 13 unchanged. Therefore, a thick evaporated film can be formed on the portion where the evaporation material 12 is evaporated on the substrate 1. Further, since the spread of the vapor can be changed without intervening physical phenomena such as changes in the temperature and evaporation amount of the evaporation materials 12 and 13, the response time until the film thickness changes can be shortened. . It should be noted that in the state shown in the drawing, the vapor flow restricting plates 14 and 15 on both sides of the crucible 10 and the crucible 1 are provided.
The vapor flow restricting plate 16 on the downstream side of 1 may be raised or lowered to adjust the spread of the vapor of the evaporation material 12 or change the mixing ratio of the vapors of the evaporation materials 12 and 13.

As described above, according to the film forming method of the vacuum vapor deposition apparatus and the vacuum vapor deposition apparatus of the present invention, the evaporation material 12,
Since the spread of 13 vapor can be changed variously, the control range of the vapor deposition film can be greatly expanded, the output of the electron gun is changed, and the pattern such as the electron beam irradiation position and irradiation time is changed. A desired vapor-deposited film can be easily formed without causing any trouble.

According to the film forming method of the vacuum vapor deposition apparatus and the vacuum vapor deposition apparatus of the present invention described above, the vapor flow regulating plates provided on both sides of each crucible are raised and lowered,
Because the vapor spread of the evaporation material is forcibly regulated,
There is no need to intervene physical phenomena such as changes in the temperature and evaporation amount of the evaporation material, and it is not necessary to change the output of the electron gun. Therefore, the response time until the thickness of the vapor deposition film changes can be significantly shortened. In addition, since the spread of the vapor of the evaporation material can be freely changed, the control range of the vapor deposition film is greatly expanded, and a desired vapor deposition film can be easily formed, which is an excellent effect.
