Overview

Wafer Dicing System. TLS-Dicing System for Separation of Silicon and Silicon Carbide Wafers. The microDICE laser micromachining system leverages TLS-Dicing – a unique technology that uses thermally induced mechanical forces to separate brittle semiconductor materials, such as silicon (Si), silicon carbide (SiC), germanium (Ge) and gallium arsenide (GaAs), into dies with outstanding edge quality while increasing manufacturing yield and throughput. Compared to traditional separation technologies, such as saw dicing and laser ablation, TLS-Dicing enables a clean process, micro-crack-free edges, and higher resulting bending strength. Capable of dicing speeds up to 300mm per second, the microDICE system provides up to a 10X increase in process throughput compared to traditional dicing systems. Its high throughput, outstanding edge quality and 300-mm wafer capable platform enables a true high-volume production process, especially for SiC-based devices. In addition, microDICE reduces the dicing cost per wafer by up to an order of magnitude or more compared to other wafer dicing approaches. Due to the contactless laser machining method, there is no tool wear and no expensive consumables are required. This results in up to 15X lower cost of ownership over the entire life-time of the dicing system.
