ABSTRACT:
In a first glass bonding process, a silicon-dioxide layer is formed on either a first or second magnetic material by vacuum evaporation. The first or second magnetic material with the silicon-dioxide layer is dipped in a warm solution containing alkali sodium or potassium for a predetermined period of time. Alkali metal is diffused on a surface of the silicon-dioxide layer to form a glass layer thereon, thereby bonding the first and second magnetic materials.
