Title:
SEMICONDUCTOR ENCAPSULATING NON-LEAD GLASS AND SEMICONDUCTOR ENCAPSULATING COATING TUBE
Document Type and Number:
WIPO Patent Application WO/2012/060337
Kind Code:
A1
Abstract:
Provided are a semiconductor encapsulating non-lead glass and a semiconductor encapsulating coating tube that are able to encapsulate a semiconductor element at a low temperature, have superior acid resistance, and that resist precipitation of crystals during glass tube formation. The present invention is characterized by the glass composition containing, by mol%, 45-58% of SiO2, 0-6% of Al2O3, 14.5-30% of B2O3, 0-3% of MgO, 0-3% of CaO, 4.2-14.2% of ZnO, 5-12% of Li2O, 0-15% of Na2O, 0-7% of K2O, 15-30% of Li2O+Na2O+K2O, and 0.1-8% of TiO2, where ZnO/Li2O is in the range of 0.84-2.
