ALBUQUERQUE, N.M., April 25, 2023 — Glass technology company 3D Glass Solutions (3DGS) has closed a $30 million series C financing round. 3DGS said it will use the funding to increase its U.S.-based manufacturing capacity for high-volume production of 3D integrated passives and substrate products. The company develops and produces glass-based 3D integrated passive solutions using a patented low-loss photosensitive glass ceramic technology. 3DGS’ system-in-package devices and components are designed for radio frequency, photonics, and data center applications, including those in the 5G, aerospace, health care, and autonomous driving sectors.

The round was led by Walden Catalyst Ventures, with participation from existing investors including Intel Capital and Lockheed Martin Ventures. Lip-Bu Tan, chair of Walden International and founding managing partner of Walden Catalyst Ventures, will join the 3DGS board of directors.

After securing a licensing agreement with Corning for process and know-how related to forming through glass vias (TGV) in Corning high-purity fused silica, as well as a corresponding long-term supply agreement for glass wafers, 3DGS last year raised $4 million in an extended series B1 funding round. The company also inked a long-term supply agreement with Menlo Microsystems.

A semiconductor is a type of material that has electrical conductivity between that of a conductor and an insulator. In other words, semiconductors have properties that are intermediate between metals (good conductors of electricity) and insulators (poor conductors of electricity). The conductivity of a semiconductor can be controlled and modified by factors such as temperature, impurities, or an applied electric field. The most common semiconductors are crystalline solids, and they are...
A substrate refers to a material or surface upon which another material or process is applied or deposited. In various fields, such as electronics, biology, chemistry, and manufacturing, the term "substrate" is used with specific contexts, but the fundamental definition remains consistent: it is the underlying material or surface that provides a foundation for subsequent processes or applications. Here are some examples of how a substrate is used in different fields: Electronics: In...
A noncrystalline, inorganic mixture of various metallic oxides fused by heating with glassifiers such as silica, or boric or phosphoric oxides. Common window or bottle glass is a mixture of soda, lime and sand, melted and cast, rolled or blown to shape. Most glasses are transparent in the visible spectrum and up to about 2.5 µm in the infrared, but some are opaque such as natural obsidian; these are, nevertheless, useful as mirror blanks. Traces of some elements such as cobalt, copper and...
