Mosaic growth and characteristics of 2-inch single-crystal diamond
Abstract
In this study, 2-inch single-crystal diamond (SCD) was fabricated via mosaic growth and laser stealth dicing. First, the growth behavior of 2 inch-scale diamond in an enclosed substrate holder was simulated, obtaining the spatial conditions conducive to continuous growth of large-area SCD. Subsequently, SCD wafers with dimensions of 50 × 25 mm2 and 48 × 48 mm2 were assembled through mosaic growth. Finally, the 48 × 48 mm2 SCD wafer was successfully and rapidly (approximately 40 min) detached by laser stealth dicing technology with a subsurface damage layer thickness of less than 100 micrometers.
