| Abstract Scope |
Mixed alkali and alkaline earth modifiers are strategically incorporated into borosilicate glass-quartz composites for 5G/6G packaging technology. Their synergistic effects, utilizing differing ionic radii and charges, disrupt ion migration pathways, creating energetic barriers that suppress ionic mobility. This achieves ultra-low dielectric loss (< 0.001) across GHz-THz frequencies. The modification simultaneously optimizes the SiO2-B2O3 network, enhancing stability and reducing non-bridging oxygen density. The composites offer tailored thermal expansion for seamless CTE matching with semiconductors (Si, GaN, SiC), enhanced mechanical robustness via ion exchange compressive stress, and essential hermeticity for mmWave signal integrity. Mixed cation doping also refines processing by lowering sintering temperatures via controlled viscous flow, mitigating phase separation, and enabling pore-free microstructures with uniform quartz dispersion. These advances deliver optimally balanced permittivity and ultra-low loss, positioning the composites as key enablers for high-aspect-ratio TGVs, miniaturized RF modules, and terahertz systems requiring suppressed interfacial polarization and thermal resilience. |
