APEX® Glass Technology and Properties
APEX® Glass is an Alumino-silicate glass with a medium coefficient of thermal expansion ideally positioned between silicon (3ppm/K) and copper (17ppm/K). APEX® Glass also has a high glass transition temperature enabling an elevated post-processing thermal window for downstream microfabrication needs.
|Coefficient of Thermal Expansion||10ppm/K|
|Glass Transition Temperature (Tg)||452 C|
|Young’s Modulus||80 GPa|
|Thermal Conductivity||1.5 W/mK|
APEX® Glass is used extensively for a number of microwave and RF applications. Leveraging APEX® Glass’ electrical characteristics with advanced manufacturing and designs is only possible with photo-definable glasses enables electronic structures with very high Q, low loss, with greater data transfer rates at lower power consumption.

APEX® Glass Technology
APEX® Glass is not like traditional glasses. It contains special sensitizers that allow unique anisotropic 3D features to be formed through a simple exposure step. This “photo-structurable glass” combines batch manufacturing processes with standard IC processing toolsets to provide a low-cost, high-volume, production solution.
APEX® Glass’ microfabrication ability is ideally suited for the wafer level packaging of electronic packages. Applications span many industries including 2.5D and 3D packaging, RF packages (inductors, antenna, etc.), optoelectronics, and microcavities among others.
