Silicon wafers are widely used for soft-lithography processes and PDMS molding. One side mirror polished, 525 µm thickness, 3 diameters available: 100 mm (4"), 76.2 mm (3"), 50.8 mm (2").
General
Our team has chosen the best wafer specifications for soft lithography. Choose between 2", 3" or 4" diameter wafers, depending on your usage.
Silicon wafers are mainly used as perfectly flat and smooth supports for photoresist patterning to create molds for PDMS microfluidic chips.
