摘要：PURPOSE:To prevent alant from entering a ca by providing a alant-stopping groove at the center of an alumina zone of a aling face with a ceramic cap.CONSTITUTION:A ceramic 1 is metallized with tungsten 2, soldered with leads 4 by an AgCu solder 3, and plated with NiAu 5. Next, aluminas 6, 6' are deposited to form a

Further, the aling part has a thickness of alant, so that airtightness improves. The alumina 6 may be made into a single layer only in a ring form inside to simplify patterning.
