Method for forming a diffusion barrier layer on a glass surface and such treated glass substrate

摘要

The method (20) involves applying (22) an acid such as citric acid, sulfuric acid or adipic acid on a substrate surface within a time period of 10-100s. The substrate surface is subjected (24) to a heat treatment by plasma effect, microwave irradiation or laser radiation up to a penetration depth of 1mu m. An independent claim is included for glass substrate.
