Low loss glass-ceramic materials, method of making same and electronic packages including same |
摘要 |
A glass-ceramic is provided having a thermal expansion coefficient in a range of 3-6 ppm/° C., a dielectric constant that is less than 5 and a Quality factor Q of at least 400. The glass-ceramic consists essentially of SiO<SUB>2 </SUB>in a range of 45-58 wt %, Al<SUB>2</SUB>O<SUB>3 </SUB>in a range of 10-18 wt % and MgO in a range of 10-25 wt %. A method of making the glass-ceramic is also provided. Further, an electronic package is also provided, including a base member and a glass-ceramic substrate bonded to the base member.
