As a package substrate, the benefits of glass are substantial. It’s extremely flat with lower thermal expansion than organic substrates, which simplifies lithography. And that’s just for starters.

Glass substrates are starting to gain traction in advanced packages, fueled by the potential for denser routing and higher signal performance than the organic substrates used today. There are still ...

Photolithography involves the selective exposure of a photosensitive material to light, using a UV light source and a collimating optical system to create an image of a patterned mask onto a substrate ...
