WebOct 28, 2024 · Lasers are promising tools for the dicing of brittle sapphire wafers as laser processing reduces cracking and chipping of the products [2,3]. Stealth dicing of transparent materials such as glass and sapphire has been extensively reported as the dicing method can minimize the kerf width and production of top surface debris by … WebApr 1, 2004 · Laser scribing offers many advantages in a manufacturing setting. The combination of a narrow kerf width, high throughput, and wide process tolerance results in a more robust process flow at lower cost. The most time consuming and costly step in dicing, and the one that causes most yield problems, is precise control of the sapphire …
