Hi colleagues, Is there a company that can provide an array of thermal oxide windows, ~0.5 to 1 um thick, dimensions something like 20 um x 100 um, spaced as needed to make the Si wafer (could be 250 um thick, for example) mechanically stable? One imagines this might be done by a. growing thermal oxide top side to 0.5 to 1 micron thickness b. patterning back side c. Bosch deep etching from back side to the oxide etch stop Thanks in advance. Junghoon
