Sensor Surface Cleaner

BusinessWire: Eco-Snow, a division of BOC (NYSE: BOX), has launched a novel dry cleaning process to remove the particles that accumulate during manufacturing and which reduce image sensor yield. The process utilizes the patented Eco-Snow(R) VersaClean(TM) 1200 system.
"Particles are the main cause of yield loss for makers of imaging devices. Traditional wet and dry cleaning methods have tradeoffs in terms of efficiency, effectiveness and environmental impact and cost. The Eco-Snow process injects carbon dioxide snow under high velocity and pressure onto the imaging device's surface, removing the particles more effectively and efficiently than alternate methods," said Joe Clark, general manager, Eco-Snow Systems.
If it works well, it might bring a major yield improvement in image sensor manufacturing process.
