November 10, 2011 — Shanghai Simgui Technology Co. Ltd., a leading Chinese wafer manufacturer, placed a follow-on order for an EV Group (EVG) EVG850 automated production bonding system for silicon-on-insulator (SOI) and direct wafer bonding. Simgui is moving from EVG’s semi-automated wafer bonder to advance high-volume SOI production.
Simgui is a spin-off from Shanghai Institute of Microsystem and Information Technology (SIMIT). It will transfer a well-established production process to the fully automated system. Currently, the company uses an EVG301 single wafer cleaning system with pre-bonding and IR inspection station.
SOI wafers are used to make micro electro mechanical systems (MEMS) and microprocessors, as well as other microelectronics.
This order comes on the heels of another EVG install in China: new customer Shenyang Silicon Technology Co. Ltd. (SST) purchased an EVG850LT automated production bonding system for silicon-on-insulator (SOI) wafers in its state-of-the-art SOI production facility this March.
EV Group recently introduced its 450mm SOI wafer bonder.
EV Group (EVG) makes wafer bonding, lithography/nanoimprint lithography (NIL) and metrology equipment, as well as photoresist coaters, cleaners and inspection systems. More information is available at www.EVGroup.com.
