METHODS FOR CONTROLLED LASER-INDUCED GROWTH OF GLASS BUMPS ON GLASS ARTICLES

A method for controlling formation of glass bumps in a glass article with laser-irradiation without the use of a growth-limiting structure. Standard deviation of height between the glass bumps on the article is less than 1 micron by controlling the laser radiation dose provided on the glass article....

Beschreibung
Zusammenfassung:	A method for controlling formation of glass bumps in a glass article with laser-irradiation without the use of a growth-limiting structure. Standard deviation of height between the glass bumps on the article is less than 1 micron by controlling the laser radiation dose provided on the glass article. L'invention concerne un procédé de commande de la formation de bosses de verre dans un article en verre avec une irradiation laser, sans utiliser de structure de limitation de croissance. L'écart type de hauteur entre les bosses de verre sur l'article est inférieur à 1 micromètre grâce à la commande de la dose de rayonnement laser fournie sur l'article en verre.
