Patent

CA 2017720

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

Cette invention concerne une méthode de dépôt de verre par rotation sur un substrat en matériau non réfractaire à bas point de fusion tel que l'aluminium. La pellicule de verre déposée par rotation selon la présente méthode est soumise à un traitement de dissociation et de dégazage de l'eau et des sous-produits de réaction puis encapsulé sous une couche diélectrique de protection résistant à la diffusion de l'humidité.
