摘要:
Bonding a metal part having a copper surface to glass, in particular a semiconductor device. A small quantity of Cr.sub.2 O.sub.3 or CuO is added to the glass. The copper is oxidized at a relatively low temperature and relatively low oxygen pressure and thereafter sealing-in is performed in a nonoxidizing atmosphere.
