How to make a conductive paint over PDMS?

Conductive paint by conventional technique using gum and graphite powder does not stick to the PDMS surface and comes off once the paint dries. How else can I make a conductive connection over the PDMS surface so that it can stick to it nicely?

What is the difference between NIL and hot embossing?

NIL (Nanoimprint lithography) and hot embossing seem to mean the same thing in many instances. Is hot embossing a subset technique of NIL? Or are they completely different methods?

What system-electronic components or physic mechanism is used to modulate signals between different devices used in lithography?

I know that pattern generator device (no pattern generator software) is needed to generate a model signal system that help you use electron diffraction for wafer surface printing by the use of the TEM. These signals are templates called patterns and…

Optics. Best way to concentrate light into delimited surface

I'm doing some experiments with 400nm UV lithography using color LCD and mono LCD and works very well (5", 2k or 4k resolution), but I'm guessing how to optimize the light source. Right now I'm using UV lamp as a source, but I think some light is…

How are components printed onto chips in lithography?

When making chips using lithographic techniques, How are the transistors and capacitors and other components "printed" onto the board? When we print one we use things like UV or E-beam to print out the shape we want (using some kind of mask), but…
