II-VI Advanced Materials and Lasertec Corporation
Announce the Purchase of a SICA88
The Advanced Materials Division of II-VI Incorporated (Nasdaq: IIVI), a world leading supplier of SiC
substrates, and Lasertec Corporation (Tokyo Stock Exchange: 6920) announced today that II-VI haspurchased a SICA88 SiC inspection & analysis tool manufactured by the Lasertec Corporation. Thisnew tool will be installed at II-VI’s SiC substrate manufacturing facility in Starkville, MS.
“This purchase enables II-VI to gather data to further it’s already state-of-art SiC substrate technology.
The SICA88 provides advanced sensitivity and analysis capabilities that II-VI can utilize to improve thequality of our SiC substrates. The addition of the SICA88 in our production line will allow II-VI to findand analyze substrate and surface defects more efficiently and effectively, in order to enhance our
defect reduction efforts, provide cutomer support to enable higher device yields, and to continue
advancing our ongoing efforts to make SiC based devices more cost effective.“ commented Dr. GaryRuland, General Manager of II-VI Advanced Materials. “In additon, the SICA88’s new
photoluminescence capability will enable us to detect other defects important to our epi and device
customers such as substrate stacking faults.“ added Dr. Ruland.
”SICA is designed to help fab engineers accelerate yield improvements by providing high sensitivity,high throughput defect inspection and highly accurate on-the-fly defect classification along with afully automated defect review feature. SICA enables SiC substrate and device manufacturers to takecorrective action sooner and improve their yields more quickly. The tool's user interface provides anintuitive graphical method for creating inspection recipes, further increasing its ease of use forautomated reporting. Lasertec will continue to pursue the development and advancement of defectinspection technologies in order to facilitate the further enhancement of power device quality andproductivity.“ said Hirokazu Seki, General Manager of Lasertec’s Technology Department 1.
