A glass-ceramic includes SiOin a range of 40 mol. % to 80 mol. %; AlOin a range of 5 mol. % to 20 mol. %; MgO in a range of 5 mol. % to 20 mol. %; and at least one of BO, ZnO, and TiO, each in a range of 0 mol. % to 10 mol. %, such that the glass-ceramic further comprises a magnesium aluminosilicate crystalline phase at a concentration in a range of 5 wt. % to 80 wt. % of the glass-ceramic.

Magnesium aluminosilicate glass ceramics

Disclosed herein are glass compositions that present several advantages over glasses and other materials currently used for redistribution layers for RF, interposers, and similar applications. The glasses disclosed herein are low cost, flat glasses that have high throughput for the laser damage and etching process used to create through glass vias (TGV). TGV generated using the silicate glasses and processes described herein have large waist diameters (D), which is a desirable feature with respect to producing glass articles such as interposers.

Silicate glass compositions useful for the efficient production of through glass vias

An article including a glass having that includes SiO, AlO, and BOand least one of LiO, NaO, KO, MgO, CaO, SrO, BaO, SnO, ZnO, LaO, F, and FeO, wherein the glass includes a dielectric constant of about 10 or less and/or a loss tangent of about 0.01 or less, both as measured with signals at 10 GHz.

Low dielectric loss glasses for electronic devices

Embodiments of a filter for electromagnetic radiation are disclosed herein. The filter includes a first glass-ceramic substrate having a first refractive index, a second glass-ceramic substrate having the first refractive index, and a first region disposed between the first glass-ceramic substrate and the second glass-ceramic substrate. The first region has a second refractive index that is less than the first refractive index. Further, the second glass-ceramic substrate is arranged substantially parallel to and spatially disposed from the first glass-ceramic substrate. The filter transmits at least 70% of electromagnetic radiation within a band of frequencies and reflects at least 80% of electromagnetic radiation outside the band of frequencies. The band of frequencies is located within the frequency range of 20 GHz to 100 GHz.

Glass-ceramic microwave filters

A glass-ceramic that includes: SiOfrom about 35 mol % to about 80 mol %; BOfrom about 10 mol % to about 50 mol %; POfrom about 10 mol % to about 50 mol %; and an optional addition of one or more of CaO, MgO and BiOfrom 0 mol % to about 5 mol %, wherein the glass-ceramic further comprises a boron-phosphate crystalline phase.
