<p>Provided is a glass for semiconductor coating that causes little environmental stress and has a high surface charge density after semiconductor surface coating. The glass for semiconductor coating is either the following (1) or (2). The glass for semiconductor coating (2) causes little environmental stress, has a high surface charge density after semiconductor surface coating, and has excellent chemical resistance. The glass for semiconductor coating (1) is essentially lead-free and contains a composition comprising, by mass%, 50% to 65% ZnO, 19% to 28% B2O3, 7% to 15% SiO2, 3% to 12% Al2O3, and 0.1% to 5% Bi2O3, while the glass for semiconductor coating (2) is essentially lead-free and contains a composition comprising, by mass%, 40% to 60% ZnO, 5% to 25% B2O3, 15% to 35% SiO2, and 3% to 12% Al2O3.</p> |
