China moves into manufacturing disruptive new semiconductor glass substrates as processor packaging competition intensifies

Glass wafer materials are gaining traction as a viable alternative to traditional organic substrates in semiconductor packaging. Major players like Samsung, AMD, and Intel are exploring glass-substrate technology to address challenges posed by increasing package sizes and wiring density. Chinese companies, including Visionix and BOE Technology, are making significant investments in glass substrate manufacturing to compete in the semiconductor market. While there are risks associated with glass substrates due to new defect modes and reliability challenges, Chinese suppliers are willing to absorb these challenges for a long-term competitive advantage. Other countries like South Korea, Taiwan, Japan, and the U.S. are also exploring glass substrates, with companies racing towards first qualification for commercialization.
