Abstract
Provided is a glass composition for protecting a semiconductor junction which contains at least SiO, AlO, ZnO, CaO and 3 mol % to 10 mol % of BO, and substantially contains none of Pb, P, As, Sb, Li, Na and K. It is preferable that a content of SiOfalls within a range of 32 mol % to 48 mol %, a content of AlOfalls within a range of 9 mol % to 13 mol %, a content of ZnO falls within a range of 18 mol % to 28 mol %, a content of CaO falls within a range of 15 mol % to 23 mol %, and a content of BOfalls within a range of 3 mol % to 10 mol %.
