Abstract:
A method of applying spin-on glass (SOG) on a substrate over low-melting point, non-refractory materials such as aluminium (1a, 1b) is disclosed. In the method a layer of applied spin-on glass (4) is subjected to disconnection and outgassing of water and reaction by-products, and then capped with a protective dielectric layer resistant to moisture diffusion (5).
