Thin Glass as a Platform for Next Generation Electronics.
David Levy, Mosaic Microsystems

Abstract
Glass substrates have excellent properties for advanced electronics and photonics applications. Glass has a large bulk resistance and low loss at radio frequencies. At the same time, it is thermally stable, moisture insensitive, and dimensionally stable, properties that allow it to be inserted in many of the processing technologies previously reserved for silicon. Additionally, the transparency of glass allows photonics application over a wide spectral range.
Mosaic specializes in the fabrication of thin glass interposers—glass devices, often 200 microns or thinner, that contain through glass vias (TGV) and electrical circuitry. Details of the laser assisted chemical etching process to produce the TGVs will be discussed, as well as subsequent processes including metallization and fabrication of more complex structures.
Integration of waveguides in these interposers is especially relevant to produce platforms for co-packaged optics, which combine electrical routing (normally with copper) and optical routing. Methods to produce waveguides on and in the glass will be reviewed.
Bio
David Levy received his Ph.D. in chemical engineering from MIT and has over 30 years of experience in chemical and semiconductor processes. As a scientist with Eastman Kodak, he contributed in fields ranging from web coating to printed electronics. He developed the Spatial Atomic Layer Deposition process, allowing patterned atmospheric deposition of semiconductors for high performance printed electronics. Prior to joining Mosaic Microsystems in 2018, he was Director of Research and Technology at Natcore, developing a novel metallization strategy for solar cells. He is currently the CTO of Mosaic, and is in charge of a research team aimed at developing and perfecting bonding, etching, and metallization processes for thin glass electronics.
