Hi to all, We are currently looking for a small wafer holder. Our wafer sample is 1cm*1cm. The wafer holder has to meet all these criteria: 1. withstand at least 450C in nitrogen 2. thermally conductive 3. exerts uniform pressure 4. small enough to fit in a 5"*6"*4" muffle furnace 5. non-reactive material Thanks, Kai Tsao
