Notice Regarding the Development of Mosaic Crystals for 2-Inch Wafer Production

Developed a 53×53×1.2 mm mosaic crystal by connecting 4 single crystals horizontally, completing the foundation for fabricating 2-inch wafers with a diameter of 50 mm. Going forward, the company aims to produce 2-inch wafers through the fabrication and cutting of component crystals and establish a mass-production system.

The reasons the company gives

The company's own explanation, not something inferred from the numbers.

Because enlarging single crystals is difficult, the company sought to achieve larger wafers using mosaic crystals, which are made by connecting multiple single crystals horizontally. The company overcame challenges involving cracking and fractures caused by stress during crystal bonding, as well as the polishing of large-area mosaic crystals.
