Title
(EN) DIMENSIONALLY STABLE GLASSES
(FR) VERRES À STABILITÉ DIMENSIONNELLE
Abstract
(EN)
Glasses that are substantially free of alkalis that possess high annealing points and, thus, good dimensional stability (i.e., low compaction) for use as TFT backplane substrates in amorphous silicon, oxide and low-temperature polysilicon TFT processes.
(FR)
L'invention concerne des verres qui sont sensiblement exempts d'alcalis qui possèdent des points de recuit élevés et, par conséquent, une bonne stabilité dimensionnelle (c'est-à-dire, un faible compactage) pour une utilisation en tant que substrats de fond de panier TFT dans des processus TFT en silicium amorphe, en oxyde et en polysilicium basse température.
