LED Output Increases with 100-mm Dicing

The Chromadice uses a UV diode-pumped solid-state (DPSS) laser system to process four 100-mm wafers per hour. Typical LED manufacture yields 10 2&#34 wafers per hour, said Jeffrey P. Sercel, president of JPSA, adding that switching to the larger 100-mm wafers will give manufacturers the equivalent of 16 2&#34 wafers per hour. JPSA developed high-accuracy Z-theta-capable air-bearing stages to enable processing with larger sapphire wafers. The Z-axis rotary stage offers continuous or limited travel, a cog-free motor, zero gear backlash, and low wobble and bearing run-out.
