Abstract

PURPOSE: To enhance the working efficiency of the evaporation device of securing a high temperature level for the resistance heating substance at the evaporation time, supplying the material of the optical reflecting metal film automatically onto the resistance heating substance and then lowering the temperature of the heating substance.
CONSTITUTION: The residual fused Al is secured at all times at concavity 7a of boron nitride heating substance 7, and Al wire 10 led out from automatic inserting device 9 is soaked into the fused Al of substance 7. In this case, the contact area of wire 10 is increased to accelerate the temperature rise of wire 10. Then Al is evaporated to face plate 1 to form Al thin film 4, and the temperature of substance 7 is lowered suddently when the necessary Al evaporation quantity is obtained. During this time, wire 10 is insetted via device 9 until right before no fusion is secured to stop the insertion. When film 4 is formed to the next plate 1, the temperature is increased again for substance 7 to repeat the above process. As a result, the working efficiency is enhanced for the evaporation device, also obtaining the steady thickness for the evaporation film.
