Samsung Electronics is ramping up its entry into the semiconductor glass substrate market by advancing its equipment procurement and installation to September, with trial production slated to begin in the fourth quarter, one quarter earlier than originally planned. According to a report from South Korean media outlet ETNews, Samsung Electronics aims to commence mass production of glass substrates for high-end System-in-Package (SiP) applications starting in 2026.

In order to manufacture highly complex multi-chiplet SiPs, Samsung has decided to expedite the trial production schedule at its Sejong plant in South Korea to gain more expertise in glass substrate manufacturing. Samsung’s competitor, Intel, also plans to offer packaging technology on glass substrates in the future.

Reportedly, Samsung Electronics plans to have all necessary equipment installed on the trial production line by September and commence operations in the fourth quarter. Partners for the trial production line include companies such as Philoptics, Chemtronics, Joongwoo M-Tech, and Germany’s LPKF, which will provide equipment components.

According to a report from Tom’s Hardware, Compared to traditional organic substrates, glass substrates offer significant advantages, including excellent flatness, which enhances exposure and focusing capabilities, as well as outstanding dimensional stability suitable for next-generation chip interconnects with multiple small chips. Additionally, glass substrates exhibit better thermal and mechanical stability, making them suitable for high-temperature durable applications in data centers.

Intel has been developing glass substrates for nearly a decade and plans to introduce commercial products by 2030. Intel believes that the characteristics of glass substrates will significantly increase interconnect density, which is crucial for efficient power transmission and signal routing in advanced SiP technology.

Previously, Intel also elaborated on its progress on the glass-based substrate packaging technology. According to Intel’s previous press release, glass substrates can tolerate higher temperatures, offer 50% less pattern distortion, and have ultra-low flatness for improved depth of focus for lithography as well as the dimensional stability needed for extremely tight layer-to-layer interconnect overlay.

As a result of these distinctive properties, a 10x increase in interconnect density is possible on glass substrates. Furthermore, improved mechanical properties of glass enable ultra-large form-factor packages with very high assembly yields.

Meanwhile, Absolics, a subsidiary of SKC America, aims to start production of glass substrates for customers as early as the second half of 2024.
