Hello all, I am not sure what we call this kind of wafer cleaning apparatus. But let me try. I am looking for a circular structure with grooves in it and a opening at the center to go onto a axis. The grooves should be able to hold 1-1.5" square wafers. The opening at the center is to put it on an axle and spin at higher speeds. I am not sure what this kind of a product is called. I need to use this in a spin dryer from FSI corporation and I cannot find any products related to that tool. I know the email sounds very vague but the whole point is to clean multiple small wafers in a spin dry equipment. Any advice would be really appreciated. Thanks, -- Pavan Samudrala
