Silicon Wafers

We have all specs that you need for your research and or production. Our silicon surface have standard Total Thickness Variations (TTV) down to 1 micron. Roughness specs are among the tightest avaialble. We carry hard to find substrates in stock or with a short leadtime.

We can also dice, reclaim, backgrind any wafer to the exact dimension and specs that you require.
