Definition of High Borosilicate Glass Wafers
High borosilicate glass is a high-performance subclass of borosilicate glass, characterized by its core formulation featuring high boron oxide (B₂O₃) content and low alkali metal oxides. Its primary components are silica (SiO₂, ~75-80%) and boron oxide (B₂O₃, ~14-18%), with strict control over alkali metal oxides such as sodium oxide (Na₂O) and potassium oxide (K₂O) (total content <3%). This formulation optimization endows it with significantly superior thermal, chemical, and optical properties compared to ordinary borosilicate glass (with B₂O₃ content of 10-15%), making it a critical base material in high-end manufacturing fields such as optics, new energy, and medical devices.
Its name derives from the composite features of "high boron" (high B₂O₃ content) and "silicate" (with SiO₂ as the matrix). In the industry, it is often abbreviated as "high borosilicate glass" or "3.3 high borosilicate glass" (named for its thermal expansion coefficient of approximately 3.3×10⁻⁶/°C).
Manufacturing Process of High Borosilicate Glass Wafers
The core of manufacturing high borosilicate glass wafers lies in precise composition control, high-temperature uniform melting, low-damage forming, and stress relief annealing. By leveraging their inherent characteristics of "low expansion and high temperature resistance," this process ultimately produces precision substrates with high flatness and low defects, serving high-end fields such as optics, MEMS, and semiconductors.
Precise control at every process step—from minor adjustments to raw material ratios to the exact regulation of annealing rates—directly determines the thermal stability and surface precision of the wafers. Only through strict adherence to these critical stages can the stringent demands of high-end applications, including optical instruments and micro-nano devices, for "ultra-precision and high-reliability" substrates be met.
