Hi Abhishek

Thank you very much for your prompt response.

For sure I'm planning to have alignment mark on the Si Master. But I
will need micrometric precision PDMS alignment, since the features I'm
considering are around 20 um and are present on both PDMS layers, so I
don't think manual alignment under a microscope will allow me such a
precise result.
