Zusammenfassung: | PURPOSE:To provide an infrared-ray transmitting window sealing method by which an infrared-ray transmitting window can be sealed against a container having the transmitting window with high airtightness and reliability. CONSTITUTION:After forming eutectic alloy layers 5 of aluminum and silicon at appropriate intervals on part of the surface of a silicon substrate 1 and metallized parts 7 are formed by successively depositing chromium, copper, and gold in this order, a filter layer 9 is formed on the non-metallized surface of the substrate 1 by alternately piling up layers having a high refractive index and layers having a low refractive index. After forming infrared-ray transmitting windows which are composed of the infrared-ray transmitting parts 9 surrounded by the metallized parts 7 in such a way, the windows are sealed to a container with the having the windows by using solder having a melting point lower than that of the substances forming the filter layer 9. |
