Abstract:
A rare-earth-containing glass material having a composition, expressed in mole percentages on and oxide basis, comprising: SiO2: 66-75 Al2O3: 11-17 B2O3: 0-4 MgO: 1-6.5 CaO: 2-7 SrO: 0-4 BaO: 0-4 Y2O3: 0-4 La2O3: 0-4 Y2O3+La2O3: 0.1-4. The inclusion of Y2O3 and/or La2O3 in the composition reduces the T2.3 of the glass thereby allowing higher annealing-point glasses to be produced. The glass is particularly useful for low-temperature polycrystalline silicon-based semiconductor devices.
